MiniMax M3
Open-weights model published by MiniMax, which also serves it through its own endpoint on OpenRouter: that rate is the maker's list price, and the other 2 hosts below are compared with it. Each figure was read on that host's own pricing page and links to it, with the date it was checked.
What each host charges
3 hosts, every one of them at $0.30 per 1M input tokens and $1.20 per 1M output tokens: no spread at all, within the 1.15× that this site treats as the same price. Pick a host on latency, region or tooling; the bill will be the same.

On OpenRouter
On September 15, 2026 OpenRouter listed 13 endpoints for MiniMax M3, 12 of them healthy, from $0.23 (CoreWeave) to $0.75 per 1M input tokens. The figure OpenRouter's catalog shows for the model, $0.30 / $1.20, is the 4th cheapest of those 13. Of these, only Minimax's own endpoint is the maker's list price; the rest are resellers. Together AI, priced above from its own page, is among them. DeepInfra, which this site stopped listing on September 6, 2026 because its own pricing page carries no price for the model, serves it once through OpenRouter; that is a reseller listing, not a published price, so the row stays out.
