How to work through it
MiniMax's official H3 release presents a task-generalized system that interprets text, images, video, and audio together and generates stereo audio with video. The Hailuo 2.3 text-to-video API documentation names a different production model and request contract. Do not assume that H3 is merely a version-number replacement inside every Hailuo surface or that account access, parameters, pricing, and migration are interchangeable.
H3's official repository distinguishes text or first-and-last-frame FL2VA from multimodal Ref2VA, and documents audio-video output plus a separate complete-system 2K path. The Hailuo 2.3 text-to-video reference documents a conventional prompt request with duration and resolution parameters. For a real selection, verify image-to-video and other current Hailuo documentation in the exact interface rather than transferring one endpoint's facts to the whole family.
Use one rights-cleared shot brief and define the viewer beat, subject, composition, action, camera, duration, aspect ratio, sound expectations, and acceptance criteria. Adapt only the syntax required by each system. Save every input, output, setting, failure, and revision. Compare instruction following, reference fidelity where supported, temporal stability, audio behavior, text, editorial repair, throughput under your conditions, and the operational work required to integrate the result.
H3 deserves evaluation when a brief depends on several related modalities, native audio-video generation, open H3-Base deployment, or the provider's complete context and regeneration path. Hailuo 2.3 may remain relevant where an established text or image workflow, existing integration, or known approval process matters more. Those are decision hypotheses, not universal conclusions; verify current docs, access, terms, and output behavior before migration.
