MiniMax: MiniMax M3.1 Flash
MiniMax M3.1 Flash 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 524,288 tokens in a single completion, which suits long documents, lengthy transcripts, or extended generated output. It supports tool calling and reasoning. The listing does not specify structured output support or whether weights are open. Pricing is $0.15 per million input tokens and $0.60 per million output tokens. That makes it worth shortlisting for high-volume or long-context workloads where per-token cost drives the decision. Its blended benchmark score of 71.3 rests on a single independent benchmark (AI Index score of 70.5), so its standing is only lightly evidenced. Teams should run their own evaluations before committing, particularly for video input or reasoning-heavy tasks.
