Hy4 preview vs wan 2.6: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Hy4 preview and wan 2.6 — 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.
wan 2.6
Unknown Developer
Generative video model for multi-shot storytelling, reference-driven outputs, and cinematic clips up to 15 seconds.
Key features
- Multi-Shot Narrative Support: Generates sequences composed of multiple shots to form a coherent short narrative rather than isolated single-shot clips.
- Reference Video Generation: Accepts or uses reference videos to guide style, motion, or framing in generated outputs to better match user intent.
- Up-to-15s Clip Output: Produces cinematic video clips with a maximum duration of 15 seconds, optimized for short-form storytelling and prototyping.
- Cinematic Styling: Prioritizes cinematic qualities (composition, pacing, and visual tone) in outputs to create film-like short clips suited for creative projects.
- Story Continuity Focus: Maintains narrative and visual continuity across successive shots to support multi-shot storytelling workflows.
- Multi-shot narrative support for composing sequences of shots into a coherent story
- Reference-video-guided generation to match style, motion, or composition from example footage
- Generates cinematic-quality video clips up to 15 seconds in length
- Optimized for short-form storytelling and multi-shot continuity
- Supports creation of prototype scenes and short cinematic sequences
Best for
- Short Film Prototyping: Rapidly generate multi-shot cinematic clips to prototype scenes and pacing before full production.
- Reference Video Creation: Produce reference sequences that demonstrate desired framing, motion, or style for collaborators or VFX teams.
- Social and Short-Form Content: Create polished 10–15 second cinematic clips for use on social platforms and promotional materials.
- Creative Storyboarding: Generate visual storyboard assets as multi-shot sequences to iterate on narrative structure and shot transitions.
- Advertising and Teasers: Produce short cinematic teasers or product-focused clips that require cohesive multi-shot storytelling.
- Creating short cinematic sequences for social media or portfolios (up to 15s)
- Prototyping multi-shot scenes for previsualization and storyboarding
- Generating reference-driven clips that mimic style and motion of source footage
- Producing short-form marketing or promotional video content
- Rapidly iterating visual concepts for filmmakers and content creators
