Hy4 preview vs Qwen3-Omni: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Hy4 preview and Qwen3-Omni — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Hy4 preview
Tencent
Tencent's open-weight Hy4 preview, a 770B-parameter Mixture-of-Experts model with 49B active parameters and a 1M-token context window.
Key features
- 770B Mixture-of-Experts Architecture: Holds 770 billion total parameters while activating only 49 billion per token, so capacity scales without proportional inference cost.
- 1M-Token Context Window: Accepts inputs exceeding one million tokens, allowing whole codebases, long document sets or extended agent traces in a single prompt.
- Apache 2.0 Open Weights: Released under a permissive licence that allows commercial use, modification and redistribution with no separate agreement.
- Productivity Task Focus: Tuned for real-world coding, office work and scientific research rather than narrow benchmark optimisation.
- Multi-Product Availability: Accessible globally through Tencent's WorkBuddy, CodeBuddy, Yuanbao and ima applications in addition to the raw weights.
- API Access via TokenHub and OpenRouter: Can be called through Tencent Cloud TokenHub or OpenRouter for teams that prefer hosted inference over self-hosting.
Best for
- Whole-Repository Code Work: Load an entire codebase into the million-token context to reason about refactors and cross-file dependencies at once.
- Long-Horizon Agent Tasks: Drive multi-step agent workflows where the full history of tool calls and intermediate results must stay in context.
- Self-Hosted Deployment: Run a frontier-scale open-weight model on private infrastructure where data cannot leave the organisation.
- Scientific Literature Analysis: Ingest large collections of papers or experimental logs and synthesise findings without chunking the input.
- Office Document Processing: Summarise, draft and restructure long reports, contracts and spreadsheets in enterprise workflows.
- Commercial Fine-Tuning: Adapt the weights for a proprietary product under the Apache 2.0 licence without negotiating a model licence.
Qwen3-Omni
Alibaba
End-to-end omni-modal large language model that understands text, audio, images, and video and can generate real-time speech.
Key features
- Omni-Modal Understanding: Processes and reasons over text, audio, images, and video within a single end-to-end model, enabling unified multimodal comprehension and cross-modal tasks.
- Real-Time Speech Generation: Produces speech outputs in real time suitable for low-latency conversational interfaces and streaming voice responses.
- Low-Latency Audio/Video Interaction: Supports streaming input and output with natural turn-taking and immediate text or speech replies for interactive audio/video sessions.
- Flexible Behavior Control: Allows fine-grained customization of model behavior and response style through system prompts and prompt-based controls for adaptation to different applications.
- Detailed Audio Captioning: Provides an open-source Qwen3-Omni-30B-A3B-Captioner variant designed for high-detail, low-hallucination audio captioning and transcription tasks.
- Multiple Specialized Variants: Offers different model builds (e.g., Instruct, Captioner, Thinking) targeted at instruction-following, detailed captioning, and reasoning workflows to fit diverse downstream needs.
- Multi-modal understanding: supports text, audio, images, and video inputs
- Real-time speech generation (low-latency TTS/streaming speech responses)
- Low-latency audio/video streaming with natural turn-taking
- Detailed audio captioner model (Qwen3-Omni-30B-A3B-Captioner) with low hallucination
- Multiple model variants (e.g., Instruct, Captioner, Thinking) for different tasks
- Flexible behavior control via system prompts for fine-grained customization
- Open-source code and model assets published on GitHub (QwenLM/Qwen3-Omni)
- Containerized deployment artifacts (Docker/containers) referenced in repo
- Community interoperability with ecosystems like Hugging Face Transformers, ModelScope, and Ollama
Best for
- Voice-First Conversational Agents: Powering low-latency voice assistants and multimodal chatbots that accept spoken queries, video context, and image inputs while responding in natural speech.
- Multimedia Understanding and Summarization: Analyzing video or audio recordings to extract summaries, scene descriptions, and cross-modal insights combining visual and auditory signals.
- Accessibility and Captioning: Generating detailed, low-hallucination audio captions and transcriptions for media accessibility, archival, and content indexing using the Captioner variant.
- Interactive Media Production: Enabling real-time voice-over generation, on-the-fly narration, and multimodal content augmentation for live streaming or virtual production workflows.
- Multimodal Instruction Following: Building assistants that take combined text, image, and audio instructions to perform tasks such as multimodal QA, document understanding, or guided workflows.
- Monitoring and Analysis of AV Streams: Real-time analysis and alerting on audio/video streams for moderation, intelligence, or quality-control applications where immediate multimodal interpretation is required.
- Real-time multimodal assistants that respond via text or speech during audio/video sessions
- Automated detailed audio captioning and transcription pipelines
- Multimodal content understanding for images and video (summarization, QA, analysis)
- Voice-enabled conversational agents with natural turn-taking
- Research and fine-tuning experiments using open-source model variants
