Model board / MiniMax M3.1 Flash

Verified 2026-10-22 against the pages listed below. Prices are USD per 1M tokens, list rate — no committed-use, enterprise or volume discount.

listed on MiniMax's own pricing page at half of M3's rate in and out ($0.30/$1.20), and a quarter of its cache read. No priority tier is listed for it, unlike M3. The 2026-10-19 GA date is from secondary coverage; the pricing page carries no date

up to 1,000,000 tokens, stated on the Hugging Face model card; MiniMax's pricing page states no window or max output

cache-read rate is stated first-party, so reads exist; the mechanics are not stated for this model. Vision, audio and tools are not stated on the pages fetched, so none is claimed

Licence: minimax-community, as named on the Hugging Face model card — the licence file was not re-read this pass

Watch out

The weights landed on Hugging Face on 2026-10-23 under minimax-community. M3's MiniMax Community License is non-commercial by default, so read this model's own licence file before self-hosting. Capability columns are unstated rather than absent; the pricing page names none

What we would use it for

MiniMax's cheapest row — half of M3 with a $0.015 cache read, and open weights to self-host

What this has cost, week by week

Output price at each refresh since 2026-10-22. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.

Nothing has moved since we started tracking it.
