## Why Included

MiniMax H3 brings short 2K video generation to Vercel AI Gateway, with text, keyframe, and multimodal reference inputs. Reference and keyframe modes cannot be combined.

## Source Summary

MiniMax H3 is available as **minimax/minimax-h3** on AI Gateway. It returns **2K MP4 videos lasting 5–15 seconds** from text, a starting image, first and last frames, or image, video, and audio references.

## Practical Implication

Use first-frame input when preserving an image’s aspect ratio matters; use references for subject or style guidance. Choose the input mode before building the request because keyframe and reference workflows use different constraints.

## Agent-Ready Context

MiniMax H3 is available as **minimax/minimax-h3** on AI Gateway. It returns **2K MP4 videos lasting 5–15 seconds** from text, a starting image, first and last frames, or image, video, and audio references.

Use first-frame input when preserving an image’s aspect ratio matters; use references for subject or style guidance. Choose the input mode before building the request because keyframe and reference workflows use different constraints.

**Reference and keyframe modes are mutually exclusive**. The material provides no generation time, price, quality evaluation, or consistency measurements across the supported aspect ratios.

## Connected Context

Feed7 judgment across 297 accumulated Signals:

This expands AI Gateway from model routing into short 2K video generation with several distinct conditioning workflows. The mutually exclusive keyframe and reference modes make input-mode selection an application-level branch, not merely a model-name swap. With no price, latency, quality, or consistency evidence, it establishes availability and interface constraints rather than a preferred video route.

- [Seedream 5.0 Pro is now available on AI Gateway](https://feed7.dev/p/seedream-5-0-pro-is-now-available-on-ai-gateway-16xbn41) — Seedream supplies image generation and editing on the same gateway, while H3 adds short video output and therefore extends a gateway-based media pipeline beyond still assets.
- [Start building with Nano Banana 2 Lite and Gemini Omni Flash](https://feed7.dev/p/gemini-omni-flash-nano-banana-2-lite-0uezrjl) — Omni Flash provides a video alternative with disclosed per-second pricing, highlighting the cost evidence missing for comparing H3 as a production route.
- [Routing rules now available on AI Gateway](https://feed7.dev/p/ai-gateway-routing-rules-024ifzc) — Gateway routing rules can centralize which model receives a request, but H3’s incompatible keyframe and reference schemas mean applications must still choose and construct the correct workflow.
