MiniMax Hailuo 2.3 API

What is MiniMax Hailuo 2.3?

MiniMax Hailuo 2.3 is the auto-routing model in the Hailuo family. Pass a prompt, a start image, or both, and it picks between text-to-video and image-to-video automatically, so one call site handles every input mix. Output is 768p (default) or 1080p in 6 or 10 second videos; 1080p locks to 6 seconds. Prompts run up to 2000 characters, with an optional prompt_optimization rewriting pass.

Best for

Mixed-input upstream forms

One endpoint handles text alone, image alone, or both — no branching call sites.

Text-first storytelling

The 2000-character prompt budget carries narrative beats and detailed scene direction.

Image-to-video without routing logic

Add start_image_url and the model switches mode by itself.

When to use Hailuo 2.3

Pick Hailuo 2.3 when the upstream form lets users mix prompts and images and you want one model that routes itself. When the workflow is image-led and latency matters more, use Hailuo 2.3 Fast. For 2K output with native audio and reference control, step up to Hailuo 3.0.
