MiniMax M3
Budgetby MiniMax
MiniMax M3 launched June 1, 2026 as an open-weight coding and agentic model built on MiniMax Sparse Attention, which swaps full attention for KV-block selection to cut long-context compute to roughly one twentieth of the previous generation at 1M tokens. It accepts text, image, and video input with a 1,048,576 token context window and up to 512K output tokens. MiniMax reports 59% on SWE-Bench Pro and 83.5 on BrowseComp, though several results were run on MiniMax infrastructure with agent scaffolding, so independent verification is still pending. API pricing is $0.30 per million input and $1.20 per million output for prompts up to 512K tokens, which MiniMax labels a permanent 50 percent discount, rising to $0.60 and $2.40 above 512K. The weights are on Hugging Face under the MiniMax Community License, which is not open source in the MIT sense: commercial use requires a Built with MiniMax M3 attribution and a notice to MiniMax, products earning more than $20 million a year need prior written authorization, and military use is prohibited.
