MINIMAX-H3 WEIGHTS ARE PUBLIC -- BUT THE OPEN-WEIGHT GRANT IS LIMITED TO THE US, EU, UK AND SOUTH KOREA, WHICH THE 7/31 ENTRY BELOW COULD NOT HAVE KNOWN (weights on Hugging Face; repo created 2026-07-28, last modified 2026-08-13; verified 2026-09-17): the MiniMaxAI/MiniMax-H3 repository carries **104 safetensors shards** and about 4.6M downloads, so the 'weights not released as of 8/03' caveat on this page is retired. **Licence: 'MiniMax H3 Community License Agreement' (HF front matter `license: other`), with an application form 'only for USA/EU/UK/South Korea'.** MiniMax's own Q&A explains why: video models face 'a more complex and rapidly evolving regulatory environment', the EU AI Act is in enforcement, and 'in the US... MiniMax is also involved in ongoing copyright-related legal proceedings specifically concerning generative video AI'; the company chose to 'release the model now with a transparent license scope' and calls the limitation 'not yet, not not ever'. **The hosted API is global** because MiniMax can enforce safeguards on its own infrastructure. Model card specifics: general-purpose omni-modal system, unified text/image/video/audio context, video with native stereo audio up to 2K and 15 seconds, task tags covering T2V, I2V, V2V, audio-to-audio-video and reference-to-audio-video, diffusers integration, plus official prompt-writing skills on GitHub. **Practical read:** H3 is now the only roster video model with published weights at this capability level, but 'open-weight' here carries a geography clause -- a licence class of its own, distinct from GLM-5.3's custom licence or Qwen's Apache 2.0, and one to state explicitly rather than summarise as 'open'.

MINIMAX MUSIC 3 -- OPEN WEIGHTS FOR FIVE-MINUTE FULL-SONG GENERATION UNDER A COMMUNITY LICENCE WITH AN ATTRIBUTION CLAUSE (2026-08-07 on Hugging Face; unrecorded until 2026-09-17): the MiniMaxAI/MiniMax-Music3 repo (created 2026-08-07, updated 2026-08-14, 56 safetensors shards) publishes **MiniMax Music 3**, 'a high-performance music generation model for creating complete songs up to five minutes long' from lyrics plus a music description. **Architecture per the model card:** an **8B Global LLM initialised from Qwen3-8B** for long-range structure, a **0.6B Local LLM** for frame-level acoustic detail, and continuous hidden-state synthesis via Flow Matching and a Flow-VAE; output is **32 kHz, 16-bit stereo WAV** at 25 frames per second. Lyrics accept explicit section tags ([Intro], [Verse], [Pre-Chorus], [Chorus], [Bridge], [Instrumental], [Solo], [Outro]); the description controls style, emotional progression, vocals, instrumentation and production. **Licence: 'MiniMax-Music3 COMMUNITY LICENSE' -- an MIT-style grant with an Acceptable Use Policy exhibit and Commercial Terms that require you to 'prominently display MiniMax-Music3 on the user interface' of any commercial product using it, plus a further clause requiring a separate prior written agreement whose scope was cut off in our fetch -- read the full LICENSE before commercial use.** No vendor benchmark table is in the card; no listening-test comparison against Suno v6 or Lyria 3.5 is published. **Why it matters:** with Suno v6 closed and label-partnered, Music 3 is the most capable open-weight song model on the roster's radar, and it is shipped by the same lab whose H3 video weights are geography-gated -- Music 3's licence carries no such territory clause in the portion read.

NEW MODEL -- MINIMAX H3 / HAILUO 3.0 (2026-07-31, vendor blog): MiniMax launched **H3**, a general-purpose **omni-modal** model that understands and generates across text, images, video and audio. Vendor-stated capability, verbatim: '**H3 understands unified context across text, images, video, and audio, generating video with native stereo sound, up to 15 seconds at 2K resolution**' -- plus instruction following, text rendering, V2V motion transfer, and multimodal editing. The headline is that audio is **jointly generated with the video** rather than added afterwards. On cost, MiniMax claims H3 runs at less than one-third the cost of mainstream models at 2K, though the post publishes no rate card. **IMPORTANT -- DO NOT LABEL THIS OPEN-WEIGHT YET.** MiniMax only *promises* weights: '**we plan to open up the model weights in the coming days**, subject to applicable laws and regulations.' As of 2026-08-03 the weights are not released, so H3 is currently a closed model from an otherwise open-weight-leaning vendor -- re-check before describing it as open. [SUPERSEDED 2026-09-17: the weights are live on Hugging Face under a community licence limited to the US, EU, UK and South Korea -- see the newer entry above]

INDEPENDENT BENCHMARK PUBLISHED (verified 2026-07-04): Artificial Analysis now has a citable M3 page (artificialanalysis.ai/models/minimax-m3, 'Released June 2026') showing an **Intelligence Index of 44**. This is lower than early social-media chatter had suggested (~55 circulated on X/LinkedIn but does not match the authoritative page) -- cite 44 as the independently-measured number. It keeps M3 solidly mid-pack among open-weights (below GLM-5.2's 51) despite the strong vendor SWE-Bench Pro 59% claim; treat vendor coding numbers and the AA general-intelligence number as measuring different things.

WEIGHTS SHIPPED (2026-06-12): **MiniMax-M3 open weights landed on HuggingFace** (MiniMaxAI/MiniMax-M3 + an MXFP8 quant) -- hitting the 'within 10 days of June 1' promise on day 10-11. Model-card specs: **~428B total / ~23B active params**, native multimodal (text/image/video input), MiniMax Sparse Attention, 1M-token context, 9x prefill / 15x decode speedup vs M2 at 1M ctx; tech report arXiv:2606.13392. LICENSE CAVEAT: **minimax-community license**, not MIT like the M2 line -- review terms before commercial self-hosting. Self-reported SWE-Bench Pro 59% now open to independent verification (Artificial Analysis pre-drop analysis pending update)

MODEL LAUNCH (2026-06-01): **MiniMax M3** -- coding/agent flagship with **1M-token context** (product page guarantees minimum 512K) and MSA sparse attention delivering vendor-claimed **>9x prefilling / >15x decoding speedups** at long context (per-token compute at 1M context = 1/20th of prior gen). Vendor-published benchmarks: SWE-Bench Pro 59.0%, Terminal-Bench 2.1 66.0%, BrowseComp 83.5 (above Opus 4.7's 79.3), PostTrainBench 37.1 (#3 behind Opus 4.7 and GPT-5.5), MCP Atlas 74.2%. WEIGHTS CAVEAT: announced as open-weight with release 'over the next 10 days,' but as of 6/10 there is NO M3 repo on HuggingFace (latest = M2.7) -- label it 'open-weight, release pending,' not available. Token Plan subscriptions: Plus $20/mo (~1.7B tokens), Max $50/mo (~5.1B), Ultra $120/mo (~9.8B)
