Exploring Alibaba's Revolutionary AI Model: HappyHorse 1.0 Feature Analysis, Application Guide and Industry Practices

2026/05/01

I. What is Happy Horse: Official Definition and Technical Background

Happy Horse, with the Chinese official name "欢乐马" (Huānlè Mǎ, meaning "Happy Horse"), is a native multimodal AI video generation large model developed by the ATH (Alibaba Token Hub) Innovation Division under Alibaba Group. Its official positioning is an important part of the ATH Business Group's "Exploration Plan for New Interaction Methods in the AI Era".

Identity Confirmation and Debut

The model first attracted widespread attention after topping the Video Arena leaderboard on the global authoritative AI evaluation platform Artificial Analysis in anonymous form in early April 2026, and was subsequently officially confirmed and claimed by Alibaba. The current public version is HappyHorse-1.0.

Core Architecture: Unified Single-Stream Transformer

Happy Horse 1.0 has achieved breakthrough design in technical architecture, with its core being a ~15 billion (15B) parameter pure self-attention single-stream Transformer model.

  • Unified modality encoding: The model abandons the common cross-attention or cascade schemes in traditional multimodal models, uniformly encodes data from four modalities (text, image, video, audio) into feature vectors (Tokens) of the same dimension at the bottom layer, and performs joint modeling and calculation in the same 40-layer Transformer network. This design aims to achieve deep fusion of information from different modalities and reduce information loss.
  • "Sandwich" layout: Its 40-layer Transformer adopts a unique layout:
    • 4 modality-specific projection layers at the head and tail respectively.
    • The 32 layers in the middle share parameters for all modalities. This structure enables natural completion of cross-modal alignment and fusion during the model calculation process.

Core Technical Background

The technical background of the model stems from Alibaba's internal exploration of next-generation multimodal interaction methods, and its core innovations are reflected in the following aspects:

  • Native audio-video joint generation: This is the most critical differentiated capability of Happy Horse. Different from the traditional process of generating video first and then dubbing later, the model can synchronously generate complete videos with lip-sync, background music and ambient sound through a single forward propagation, achieving native alignment of audio and video on the physical time axis.
  • Efficient inference and speed optimization:
    • The model adopts advanced DMD-2 (Distribution Matching Distillation v2) distillation technology, compressing the denoising inference steps to only 8 steps without using classifier-free guidance (CFG), greatly reducing computing overhead.
    • Cooperated with the optimized runtime, it takes only about 38 seconds to generate a 5-second 1080p video with synchronized audio on a single NVIDIA H100 GPU, showing excellent generation efficiency.
  • Multilingual lip sync: Thanks to the unified architecture, when generating character dialogue videos, the model can strongly bind audio waveform features with facial muscle movement trajectories, thus natively supporting accurate lip sync for 7 languages: English, Mandarin, Cantonese, Japanese, Korean, German and French.

Performance and R&D Background

  • Authoritative evaluation results: In the blind test leaderboard of Artificial Analysis Video Arena, Happy Horse-1.0 once ranked first in Elo scores for both core tracks: text-to-video (no audio) and image-to-video (no audio), surpassing mainstream models including ByteDance's Seedance 2.0.
  • Authoritative evaluation results: In the blind test leaderboard of Artificial Analysis Video Arena, Happy Horse-1.0 once ranked first in Elo scores for both core tracks: text-to-video (no audio) and image-to-video (no audio), surpassing mainstream models including ByteDance's Seedance 2.0.
  • R&D team: The project is led by Zhang Di, former Vice President of Kuaishou and technical head of Kling AI. The team responsible for model R&D is led by Zheng Bo, Vice President of Alibaba. The team was originally affiliated to the Future Life Laboratory of Taotian Group, and was later transferred to the newly established ATH Business Group.
  • Release and access: According to official information, the model will provide API services through the Alibaba Cloud Bailian Platform. As of April 2026, the official has released information through its Weibo account @HappyHorse_AI, and clearly denied the existence of any so-called "official website", stating that it is a product under development.

II. In-depth Disassembly of Core Architecture and Functional Features

Following its disruptive debut performance, the powerful capabilities of Happy Horse 1.0 stem from a radical and efficient underlying technical architecture. It not only represents the current frontier level of video generation models, but more importantly, this design clearly points to the core paradigm of next-generation multimodal interaction.

📈 Authoritative Certification: The Performance King Behind the Leaderboard

Internal manual evaluationIn 2000 comparisons, scores for visual quality and text alignment are the highest, with a win rate of over 60%.Indicates that the model not only has high "benchmark scores", but also excels in actual generation quality, reliability of following user instructions and controllability.

These results are no accident, but the direct embodiment of its underlying architecture innovation.

🏗️ Architecture Cornerstone: Unified Single-Stream Transformer

Happy Horse 1.0 abandons the multi-tower architecture or cross-attention mechanism common in traditional multimodal models, and chooses a more concise and powerful path: a 15-billion-parameter, pure self-attention single-stream Transformer network (specifically a 40-layer Diffusion Transformer).

The core innovations of this architecture lie in "unified modality encoding" and "parameter-shared fusion":

  • Unified modality tokens: The model uniformly maps data from four modalities (text, image (single frame), video (continuous frames) and audio waveforms) into feature vector sequences of the same dimension at the input end. This means that a description, a sketch, a few seconds of video clips and a piece of background music are converted into the same type of "language" in the model's view.
  • Unique "sandwich" layout: Its 40-layer network is not homogeneous. It uses 4 layers at the head and tail as modality-specific projection layers, responsible for encoding raw data into the unified space and decoding fused features back to various modalities; while the 32 key Transformer layers in the middle have parameters fully shared by all modalities. This design forces the model to learn to understand and fuse cross-modal information associations in the deep denoising and generation process, so as to realize end-to-end joint modeling.

The fundamental advantages brought are: the shortest information transmission path, avoiding error accumulation in cascade models; the alignment of visual and audio on the physical time axis is naturally achieved during the generation process, rather than post-splicing, which fundamentally solves industry pain points such as lip-sync mismatch and audio-video separation.

🎬 Ace Feature: Native Audio-Video Joint Generation

This is the most dazzling fruit of the above unified architecture, and also the confidence for Happy Horse to be called a "pocket movie studio".

  • One-click video generation: Users only need to input text prompts (or combine reference images), and the model can synchronously output complete video files with matching background music, ambient sound effects, and (if involving characters) precise lip-sync actions through a single forward propagation. This completely bids farewell to the traditional, fragmented three-stage workflow of "AI generates silent video → find or generate dubbing → use lip-sync tools for post-synthesis".

  • Seven-language lip sync: Thanks to the joint training of audio and video features in the unified space, the model natively supports lip sync for 7 languages: English, Mandarin, Cantonese, Japanese, Korean, German, French. Its Word Error Rate (WER) is at the leading level among open-source models, making scenarios such as generating virtual character broadcasts and multilingual teaching videos extremely simple.

⚡️ Efficiency Revolution: Ultra-Fast Inference and Full-Stack Optimization

In order to transform powerful capabilities into affordable productivity, Happy Horse has done in-depth optimization in inference efficiency:

  • Distillation for speedup: Adopting advanced DMD-2 (Distribution Matching Distillation v2) technology, the standard steps required for diffusion model denoising (usually 25-50 steps) are compressed to only 8 steps, and no classifier-free guidance (CFG) is required, which greatly reduces computation without losing quality.
  • Compilation acceleration: Cooperated with Alibaba's self-developed MagiCompiler full-graph compilation runtime to deeply optimize the calculation graph and maximize GPU utilization.
  • Measured performance: Finally realized the ultra-fast experience of generating a 5-second, 1080p resolution, complete video with synchronized audio on a single NVIDIA H100 GPU in only about 38 seconds. In contrast, many similar models take minutes to generate videos without audio. This lays the foundation for application scenarios such as batch generation and real-time interaction.

🌍 Ecosystem Strategy: Open Source and Commercial Friendly

Different from many top models that choose closed-source commercialization, Happy Horse 1.0 adopts a more ambitious strategy: fully open source and support commercial use. The official released full sets of weights and inference codes including the base model, distillation version, and super-resolution module, using commercial-friendly licenses such as Apache 2.0.

The significance of this strategy is:

  1. Lower threshold: Any developer or enterprise can deploy it on their own servers, fully controlling data privacy and business processes.
  2. Promote innovation: Open source attracts global developer communities to conduct research, improvement and secondary development, and quickly spawn upper-layer application ecosystems.
  3. Change the pattern: It proves that in the cutting-edge field of AI video generation, the open-source route can also achieve or even surpass the top quality of closed-source products, providing new basic options and competition dimensions for the entire industry.

In short, the core architecture of Happy Horse 1.0 is a well-designed unified multimodal system, and its functional features all revolve around the goal of "efficiently generating native audio-video integrated content". It is not only the leader in technical indicators, but also a paradigm reconstruction of the video content production workflow. Next, we will specifically look at how to apply this powerful capability to practical work.

        "resolution": "720P",
        "ratio": "16:9",
        "duration": 5
    }
}'

Prompt engineering suggestions: For best results, structured descriptions containing elements such as subject, scene, action, atmosphere/style are recommended. Chinese descriptions usually have better effects.

🖥️ Path 2: Local Deployment and Secondary Development (Advanced Customization)

For teams with data privacy, high concurrency requirements or hope for deep customization, the full open source (Apache 2.0 license) of Happy Horse provides the possibility of local private deployment. This is a path with high threshold but maximum freedom.

Step 1: Evaluate and meet rigid prerequisites

Hardware is the first and highest threshold for successful local deployment.

  • GPU (rigid requirement):
    • Recommended configuration: NVIDIA H100 or A100 with ≥ 80GB VRAM. This is the official benchmark test environment, where generating a 5-second 1080p video takes about 38 seconds.
    • Minimum requirement: NVIDIA RTX 4090 (24GB VRAM). Quantization technology must be used with reduced output resolution (e.g. 720p), and generation time may be extended to several minutes.
    • Minimum requirement: NVIDIA RTX 4090 (24GB VRAM). Quantization technology must be used with reduced output resolution (e.g. 720p), and generation time may be extended to several minutes.
    • Not supported: Consumer-grade graphics cards with less than 24GB VRAM, or Apple Silicon (Mac), AMD graphics cards (currently heavily dependent on the NVIDIA CUDA ecosystem).
  • Software and environment:
    • Operating System: Linux (Ubuntu 20.04/22.04) is preferred, Windows can be tried via WSL2.
    • CUDA: CUDA 12.x or higher and corresponding drivers must be installed.
    • Python: Python 3.10+ is recommended, and a virtual environment should be created via conda or venv.

Step 2: Get code, weights and configure environment

  • Clone official repository: Get inference code from the official designated GitHub repository or ModelScope, Hugging Face pages.
git clone https://github.com/happyhorse-ai/HappyHorse.git  # Example, subject to official release
cd HappyHorse
  • Install dependencies: Install all Python packages required by the project in the virtual environment.
pip install -r requirements.txt
# Ensure PyTorch matching the CUDA version is installed
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
  • Download model weights: Download the huge model weight files (tens of GB) from the official platform.
# Method 1: Use Hugging Face CLI
huggingface-cli download happyhorse/HappyHorse-1.0 --local-dir ./models
# Method 2: Use ModelScope (better for domestic networks)
from modelscope import snapshot_download
model_dir = snapshot_download('ali/HappyHorse-1.0')

Step 3: Run tests and secondary development integration

After successful deployment, you can call via command line or Python API.

Basic command line call example:

python demo.py --prompt "一只金色的凤凰在夜空中飞翔" --duration 5 --resolution 1080p --output ./output.mp4

Python API integration example (basis for secondary development):

This is the core of embedding model capabilities into your own applications.

import torch
from happyhorse import HappyHorsePipeline  # Class name subject to official release

# 1. Load the model to GPU
pipeline = HappyHorsePipeline.from_pretrained("./models/happyhorse-1.0", torch_dtype=torch.float16)
pipeline.to("cuda")

# 2. Configure generation parameters
generation_params = {
    "prompt": "一位女孩在海边奔跑,黄昏光线",
    "num_frames": 48,        # ~5 seconds @ 24fps
    "resolution": "1080p",
    "audio_sync": True,      # Enable native audio-video generation
    "language": "mandarin"   # Set Mandarin lip sync
}

# 3. Execute generation and save
video_output, audio_output = pipeline(**generation_params)
video_output.save("./output/girl_running.mp4")

Common problems and optimization

  • Out of Memory (OOM): Reduce resolution; enable attention slicing; wait for the quantized version (INT8/FP8) released by the community.
  • Slow generation: Confirm that the model is loaded on the GPU; check if it is a hardware bottleneck. Happy Horse itself only requires 8 denoising steps, and its efficiency is already high.
  • Hardware not up to standard: You can temporarily use the Bailian Platform API as an alternative; or pay attention to the workflow nodes developed by the community for tools such as ComfyUI.

Important reminder: Local deployment involves a lot of resources and technical requirements. Before starting, be sure to verify the latest code repository, weight download links and deployment documents through the official Weibo @HappyHorse_AI to avoid risks caused by non-official channels.

Through the above two paths, you can flexibly choose to integrate Happy Horse into your business flow according to your team's technical capabilities, resource budget and security needs, whether it is cloud call for rapid launch or local deployment with deep control.

The key to transforming technical advantages into commercial value lies in accurately embedding it into specific workflows. This section will deeply analyze its implementation cases in the four core fields of e-commerce, advertising, short drama and training, as well as the best practices extracted from them, combining official public information.

🎬 Four Industry Application Matrix: Pain Points and Solutions

Before diving into cases, let's take a look at how Happy Horse breaks through the classic problems of different industries through the table below:

IndustryPain PointsSolutionUse Cases
E-commerce & RetailMassive product images need to be dynamized, traditional video production has high cost and long cycle.Batch reference-to-video, quickly transform product detail page images into vivid use scenario videos, lowering the threshold for small and medium-sized merchants.Product display short videos, virtual anchor broadcasts, scenario-based marketing videos.
Advertising & MarketingHigh cost of creative A/B testing, low efficiency of multi-market material adaptation.Batch text-to-video and video editing, quickly produce multi-version advertisements for effect testing, support multilingual lip sync.Multi-version creative advertising testing, social media materials, localized broadcast videos.
Pan-entertainment & Short DramaFast content consumption, high shooting cost, complex actor schedules and scene coordination.Efficient multi-lens narrative, combined with detailed prompts, a single person can quickly produce plot fragments with coherent camera work.Short drama/micro drama fragments, plot short videos, stylized content creation.
Corporate Training & Knowledge PaymentKnowledge content production is boring, converting text and PPT into videos is time-consuming and laborious.Text-to-video and reference-to-video, one-click convert course outlines and product descriptions into dynamic demonstrations to improve information absorption rate.Course supporting videos, product function explanations, internal training materials, SaaS product demonstrations.

📦 E-commerce Industry: From "Static Images" to "Scenarios", Driving Conversion Rate Surge

Real case:

A solar fountain pump merchant used Happy Horse's Reference-to-Video capability to transform static product function description images into vivid scene videos of fountains working in bird baths, fish ponds and children's bathtubs. This upgraded the dry "parameter description" to an immersive "user experience", achieving a significant surge in product sales.

Application analysis:

The core of e-commerce is "display" and "trust". The value chain of Happy Horse in this scenario is clear:

  1. Material source: Directly call product white background images and scene images as reference images in input.media.
  2. Prompt engineering: Structured description around "subject + scene + action + effect". For example, for a coffee machine: Prompt: "Stainless steel coffee machine character1 placed on a log-style dining table, morning sun through the window. Close-up shot of the steam spraying out after pressing the switch, completing a latte with a heart-shaped pattern, with soft morning music in the background."
  3. Technical implementation: Call the happyhorse-1.0-r2v model to batch generate short videos within 15 seconds, seamlessly connecting to product detail pages or short video platforms.

Best practice focus:

  • Prioritize high-value scenarios: Prioritize products with high potential or categories requiring complex scenario demonstrations (such as home furnishings, toys, appliances) to maximize ROI.
  • Detailed prompts: Details determine realism. Describing "sun angle", "steam texture" and "background sound effects" can generate much higher quality videos than "make coffee".

📢 Advertising & Marketing: Unlock "Creative Experiment Freedom", Accelerate Material Production

Real case:

Global advertising and marketing service provider Nativex has announced access to the Happy Horse large model, aiming to help advertisers improve efficiency in advertising material production, creative testing and multi-market content adaptation. This means that an advertising idea can generate dozens of variants for A/B testing in a very short time based on different copy, tones, and actor images (controlled by reference images).

Application analysis:

The core of modern digital marketing is "data-driven rapid iteration". Happy Horse becomes a "super-high-speed prototype machine" for creativity.

  1. Multi-version generation: Fix the scene description, only modify the "style keywords" in the prompt (such as "cyberpunk neon", "warm family filter") or "call-to-action copy", and batch generate via API.
  2. Localized adaptation: Use its seven-language lip sync capability to generate different dubbing versions (English, Japanese, German, etc.) for the same video content, realizing one-click localization of global marketing content.
  3. Video editing application: For existing high-quality advertisements, use the happyhorse-1.0-video-edit model to change model costumes or product appearances combined with reference images, extending the life cycle of successful materials.

Best practice focus:

  • Establish creative template library: Solidify verified effective camera languages and camera movements into prompt templates to improve team reuse efficiency.
  • Human-machine collaborative review: AI is responsible for quickly generating "creative options", and human marketing experts are responsible for final screening and optimization based on brand tone and data feedback to ensure strategic correctness.

🎭 Short Drama & Pan-Entertainment: Content "Amplifier" for Individual Creators

Real case:

During the internal test of the Qianwen App, creators used Happy Horse to generate a large number of stylized short films with TVB Hong Kong style, CCTV Romance of the Three Kingdoms style, and old movie texture. Through fine prompt control, multi-lens coherent narratives were realized, and videos of the same style could be generated with one click.

Application analysis:

The short drama market has a dual thirst for "output" and "style". Happy Horse's 15-second multi-lens narrative and film-grade image quality control capabilities exactly match.

  1. Storyboard script is prompt: Directly convert short drama scripts into structured prompts. For example: Prompt: "Medieval castle study, candlelight flickering. Wizard character1 in black robe (close-up of his melancholy eyes) slowly puts down the ancient book in his hand, walks to the window (medium shot pushing in). Lightning and thunder outside the window, illuminating the magic light ball suddenly appearing in his hand (close-up of the hand)."
  2. Style consistency: Set a fixed seed (random seed) in parameters, combined with stylized keywords, to ensure stable picture style for the same series of short dramas.
  3. Efficient productivity: For monthly subscribers, the feature of unlimited concurrent tasks enables individuals or small teams to have parallel production capabilities comparable to small studios.

Best practice focus:

  • Camera language coding: Actively use professional terms such as "close-up", "panorama", "pan shot", "slow motion" in prompts to more accurately control the narrative rhythm and cinematic sense of the video.
  • Iterative optimization: When the first generation result is not perfect, adopt the "minimum change" principle, adjust only one variable in the prompt (such as "change 'walk' to 'stagger walk'"), to accumulate empirical knowledge of model understanding.

🎓 Corporate Training & Knowledge Dissemination: Animate "Static Knowledge"

Application analysis:

In the field of knowledge transfer, the acceptance of video is much higher than that of text. Happy Horse can transform boring documents and PPT pages into dynamic demonstrations that are easy to understand.

  1. Product demo videos: For each function point of SaaS software, use text-to-video to make 3-5 second motion effects demos. For example, describe "on the data dashboard page, after the user clicks the filter, the chart updates dynamically in real time".
  2. Internal training materials: Present text clauses such as safety regulations and operation procedures through visualized scenario videos to improve memory points.
  3. Knowledge payment courses: Generate visual supplementary videos for audio courses or graphic columns to improve course added value.

Best practice focus:

  • Clear technical boundaries: Clearly understand that the model is good at expressing conceptual and step-by-step visual content, but for scenarios requiring precise data charts and complex logical animations, it needs to be combined with traditional animation tools.
  • Structured content production: Modularize the training system, and each module corresponds to a video generation task, which is convenient for management and updating.

💡 Cross-Industry Best Practice Overview

Combining the above cases, to successfully control Happy Horse and realize commercial value, enterprises should follow the following core practice guidelines:

  • Strategy first, precise selection: Prioritize deploying the model in business links with high repetition, large batches, and high requirements for creative iteration speed, such as e-commerce product videos and advertising material testing. Avoid using it in scenarios with strict requirements for absolute physical accuracy and long logical chains.
  • Master "prompt engineering": This is the core skill to control model output. You must develop the habit of writing structured prompts: [Subject] in [Scene], performing [Action], with [Style/Atmosphere], and background [Sound Effects]. This is the key leap from "usable video" to "high-quality video".
  • Choose the optimal technical path:
    • Lightweight trial/personal creation: Experience through the free quota of the Qianwen App.
    • Enterprise-level system integration and batch production: Must apply for API through the Alibaba Cloud Bailian Platform for automated calls. The privilege of no queuing and unlimited concurrency for monthly subscribers is the key to ensuring team productivity.
    • Extreme requirements for data security and customization: Consider local private deployment based on the Apache 2.0 open source license, but this requires H100/A100 level hardware and corresponding technical teams.
  • Build a new human-machine collaborative process: Redefine team roles. AI acts as a "super producer" and "creative inspiration library", responsible for massive generation and rapid iteration; the human team focuses on top-level creative design, prompt strategy optimization, brand compliance review, and final decision-making based on business data. This is not substitution, but liberation and upgrading of productivity.

V. References and Subsequent Access Channels

To ensure that you obtain the most authoritative and timely information about Happy Horse (HappyHorse-1.0) and use the model service safely and effectively, this chapter summarizes verified official channels, core references and key reminders.

🎯 Core Summary and Anti-Fraud Reminders

First of all, please keep the following two points in mind, which are the keys to distinguishing true and false information and avoiding risks:

  1. Official confirmation of "temporary non-open source": According to the statement of Alibaba official through authoritative media channels, the Happy Horse-1.0 model weights and inference code will not be open-sourced for the time being. Any links claiming to provide "official GitHub source code" or "complete weight download" on the Internet are not official releases, and may be community resource navigation, summaries or third-party projects.
  2. Only official voice channel: The model is officially owned by Alibaba ATH (Alibaba Token Hub) Innovation Division, and its only designated public information release channel is the Sina Weibo account @HappyHorse_AI. Any claimed "official website" or independent technology blog is currently not officially recognized.

📢 Only Official Information Release and Update Channel

  • Official Weibo: @HappyHorse_AI
    • Nature: The "hub" of official information release. All important model updates, service launch announcements, major technical explanations, and clarifications on information circulating on the network will be released through this account as soon as possible.
    • Verification method: Weibo has obtained "enterprise certification", which is the most direct basis for confirming its official identity. You can view its past releases through this account, and all statements related to Alibaba Cloud Bailian Platform and Alibaba ATH team are from here.
    • Role: Subscribing to this account is the best way to get "first-hand information" and avoid being misled.

📊 Authoritative Third-Party Evaluation and Performance Verification

To objectively understand the benchmark status of Happy Horse's performance, the following independent evaluation reports are core references:

  • Artificial Analysis Video Arena

    Blind Test Leaderboard

    • Source: Third-party independent evaluation platform Artificial Analysis.
    • Authority: Adopting the blind test mechanism of "blind two-choice" by global users and the Elo scoring system, it is widely regarded as one of the most credible AI video generation model leaderboards.
    • Key data (as of April 27, 2026):
      • In the text-to-video (no audio) and image-to-video (no audio) tracks, HappyHorse-1.0 ranked first, with Elo scores significantly leading the second place (such as Seedance 2.0).
      • In the comprehensive track with audio, the model temporarily ranks second in the industry, but is still at the top level.
    • Significance: This leaderboard data is the most powerful public evidence that HappyHorse-1.0's core visual generation capability has reached the world's leading level.
  • Official internal quality evaluation data

    • According to public reports, in the internal evaluation of 2000 manual comparisons, HappyHorse-1.0 is superior to mainstream open-source models such as OVI 1.1 and LTX 2.3 in dimensions such as visual quality and text alignment.
    • Its Word Error Rate (WER) is as low as 14.60%, proving its native advantage in multilingual lip sync.

🔬 Current Credible Sources of Technical Details

Since the official technical paper (such as arXiv preprint) has not been released, understanding its technical architecture currently requires integrating high-confidence reports from multiple parties:

  1. Comprehensive technical reports: You can refer to authoritative encyclopedia entries or in-depth technical analysis articles that integrate multi-party information, which usually cover the following widely cited technical highlights:
    • Unified architecture: ~15 billion parameter single-stream Transformer (40 layers), unified processing of text, image, audio and video modalities.
    • Core technology: Adopt DMD-2 (Distribution Matching Distillation v2) distillation technology to compress denoising steps to 8 steps, realizing fast inference.
    • Native synchronization: The model can synchronously generate video, audio and precise lip sync in a single inference.
    • Multilingual support: Natively supports lip sync for 7 languages: English, Chinese, Cantonese, Japanese, Korean, German, French.
  2. Core reporting sources: Information about model release, technical attribution (Alibaba ATH team) and commercial plan (Bailian Platform API) was initially reported and confirmed by international authoritative financial and technology media including Bloomberg and CNBC, which can be regarded as important evidence for technical information.

🚀 Current Path for Model Access and Use

According to the official plan, the ways to obtain and use the model are as follows:

  • API Service (Only Official Commercial Access Point):
    • Platform: Alibaba Cloud Bailian Platform (https://bailian.console.aliyun.com).
    • Status: Has gradually opened testing to enterprise customers since April 27, 2026, and plans to officially launch the API interface on April 30.
    • Operation: Register an Alibaba Cloud enterprise account, apply to access the Bailian Platform and wait for review/quota approval. For specific API endpoints, parameters, billing standards and sample code, please refer to the official platform documentation.
  • Local Deployment:
    • Current status: Not feasible. Since the official has clearly stated that it will not be open-sourced for the time being, there are no official weight files and inference code libraries available for download for local deployment.
    • Possible future: Whether and when to open source needs to pay close attention to the final announcement of the official Weibo @HappyHorse_AI.

Summary: For developers and researchers, the most realistic path at present is to follow the official Weibo to get updates, and apply to use its API service through Alibaba Cloud Bailian Platform. All information about "source code download" and "local deployment tutorials" should be treated with caution and verified for sources before the official formal open source.
