When Was MiniMax H3 Released?

Overview

MiniMax H3 was announced on July 31, 2026, as the latest model in MiniMax’s Hailuo video line (Hailuo 3.0). At announcement it launched API-only; the open weights were described as coming “in the coming days” but had not shipped as of early August. So there are effectively two dates to track: the July 31 API launch, and a later, still-pending open-weight release. Source note: Verified 2026-08-06 against the MiniMax official H3 blog, MiniMax Video Generation API docs, and Hugging Face MiniMax-H3 model page.

This staged pattern is common for new video models — an API or preview first, then wider access or open weights afterward — so “the release date” depends on which access path you mean. If you are planning around it, note the July 31 API availability and treat the open-weight release as announced-but-not-yet-dated.

For your own content or documentation, record the specific version and access route alongside the date, and re-verify on MiniMax’s official channels, since a point release or the weight drop can change capabilities or terms without a loud announcement that reaches every third-party article.

The reliable habit: cite the official source for the date, note the version you actually used, and revisit when you start a new project.
