A Tier · 8.4/10

**MiniMax-H3's weights are public on Hugging Face (repo 2026-07-28, updated 2026-08-13) under a community licence whose open-weight grant is limited to the US, EU, UK and South Korea**, and **MiniMax Music 3 (2026-08-07)** ships open weights for five-minute full-song generation with a prominent-attribution commercial clause. MiniMax's coding/agent flagship -- M3 (June 1 2026): 1M-token context, MSA sparse attention (>15x decoding speedup at long context), SWE-Bench Pro 59.0%, Terminal-Bench 66.0%. OPEN WEIGHTS LIVE on HuggingFace since June 12 (~428B total / ~23B active, native multimodal, minimax-community license)

Personality & Tone

The Chinese multimodal generalist

Tone: Expressive and media-rich. MiniMax's chat models lean into long, formatted responses and handle voice and image prompts more naturally than most pure-text peers.

Quirks: Strong multimodal story; text-only quality is good but not class-leading versus DeepSeek or Qwen. Like other Chinese models, careful on domestic political topics.

The Good and the Bad

What we like

  • +229B/10B-active MoE delivers Tier-1 agentic performance with the smallest active footprint in its class -- M2.7 hits 56.22% on SWE-Bench Pro and 57.0% on Terminal Bench 2
  • +Sparse MoE design: ~10B active params during inference means fast and cheap to run despite 229B total
  • +M2 / M2.5 (predecessors) carry true MIT licensing with zero commercial restrictions; M2.7 license needs verification (HF lists 'Other')
  • +Native agentic and tool-use training -- positioned as a 'self-evolving agent model'
  • +Per-layer QK-Norm + full-attention blocks make long-context stable
  • +Strong cost-to-performance ratio for agentic workloads vs closed frontier models

What could be better

  • −Smaller Western community than Qwen/DeepSeek -- tutorials sparse
  • −Ollama support arrived late -- community relied on vLLM for months
  • −English writing tone is noticeably less polished than Claude or Mistral
  • −PRC content filters apply
  • −MiniMax as a lab is less well-known than Alibaba or DeepSeek -- some enterprise buyers hesitate

Known Issues

  • 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'.Source: Hugging Face (huggingface.co/MiniMaxAI/MiniMax-H3 -- API metadata createdAt 2026-07-28, lastModified 2026-08-13, 104 .safetensors; raw README.md front matter license_name minimax-h3-community-license-agreement; docs/QA-about-License.md) -- all fetched 2026-09-17 · 2026-09-17
  • 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.Source: Hugging Face (huggingface.co/MiniMaxAI/MiniMax-Music3 -- API metadata createdAt 2026-08-07, lastModified 2026-08-14, 56 .safetensors; raw README.md; raw LICENSE, first ~1,200 characters) -- all fetched 2026-09-17 · 2026-08-07
  • 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.

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.Source: Artificial Analysis (artificialanalysis.ai/models/minimax-m3) · 2026-07-04

The old 'first open-weight to hit 80.2% SWE-Bench Verified matching Opus 4.6' framing was an M2.5-on-different-bench claim and does NOT carry forward to M2.7 directly -- SWE-Bench Pro and SWE-Bench Verified are not comparable.

Best for

Agentic coding and tool-use workflows on a budget. Best price-to-SWE-Bench ratio of any open-weights model in 2026.

Not for

Teams that prioritize polished English writing (Mistral Large 3 or Claude are better), or anyone who needs the deepest ecosystem support (Llama is still that).

Our Verdict

MiniMax M2/M2.5 is the most cost-efficient frontier-tier open model in 2026. The 80.2% SWE-Bench Verified score is a genuine breakthrough -- matching Claude Opus 4.6 on real coding tasks at a tenth of the price. The sparse 10B-active MoE runs fast on moderate hardware. The main drawback is ecosystem: MiniMax has less Western infrastructure support than Alibaba or DeepSeek. If you're building an agentic product and want maximum value per token, M2.5 is an A-tier pick.
