Should I use this for coding agents

Use M3 when you want MiniMax’s open checkpoint. AA 45 and vals 42.72% are cited; we do not invent a DeepSWE percent.

When not to use it

Trust this before you buy

  • No official DeepSWE row. AA 45 and vals 42.72% are different harnesses; do not average them.
  • License is minimax-community, not Apache. No official GGUF on this repo. Hub usedStorage is about 2× the tree shard-byte sum, cited separately.
  • Not a Continuum hosted id.

Plus is $25/mo with $25 weekly hosted usage. The Mac app stays free with your own keys. Get Plus is not Download for Mac.

The snapshot was capped at 12 shards when the tree API was read on 2026-08-19, so the remaining 47 are on the Files tab, not on this page. Totals above are the full tree API sum, not this slice.

Continuum serving

Not listed as a Continuum hosted id. OpenRouter minimax/minimax-m3.

Continuum hosted id not on the host list

We list first-party and OpenRouter, plus Continuum only when the live public allowlist named the id. This is not a 15-host routing table.

FAQ

Why no DeepSWE chip?

The official DeepSWE board updated 13 Aug 2026 did not list MiniMax M3. Omitting is the rule.

Why does the lab blog disagree with DeepSWE or Scale?

Lab posts pick a harness, an effort, a split, and sometimes a private eval set. DeepSWE publishes the official mini-swe-agent row with cost, tokens, and steps. Scale SWE-bench Pro only counts when the public shared-harness board has a row we can fetch. A higher lab number is usually a different test, not a better one.

OpenAI-compatible call

No Continuum hosted id is verified for this model, so this page does not invent a curl target. Use the first-party API or the OpenRouter slug minimax/minimax-m3.
