MiniMax: MiniMax M3
MiniMax M3 is a model from MiniMax that accepts text, image, and video input. It offers a context window of 1,048,576 tokens and can return up to 512,000 tokens in a single completion, which suits long documents, large codebases, or lengthy media-derived transcripts. It supports tool calling and reasoning. The listing does not specify structured output support or whether weights are open, so confirm both before relying on them. At $0.30 per million input tokens and $1.20 per million output tokens, it belongs on the shortlist for teams that need very long context and multimodal input on a modest budget. The benchmark evidence is thin: its blended score of 47.2 comes from a single independent benchmark, where it scored 48.2 on the AI Index. Treat its quality as unproven, and test it on your own workloads before you commit.
