MiniMax M3.1 Flash - access through LLMTR
MiniMax M3.1 Flash is MiniMax's model for coding, tool-using agents and long-context work. It provides a 1,000,000-token context, returns at most 524,288 tokens per response and accepts text, images and video. Tool calling and JSON object mode work, and prompt caching is supported. Reasoning depth is set with reasoning_effort from low to max; reasoning cannot be turned off, so pick a lower level to reduce latency. Reasoning counts toward the output limit, so do not set max_tokens low.

Guides about this model
- MiniMax M3.1 Flash API: first request, reasoning_effort, price - On LLMTR, MiniMax M3.1 Flash is called as minimax/minimax-m3.1-flash on /v1/chat/completions. It has a 1,000,000-token context, returns at most 524,288 tokens per response and takes text, image and video input; it costs $0.15 input, $0.015 cached input and $0.60 output per 1M tokens.
- MiniMax M3.1 Flash or M3? Price and feature differences - On LLMTR both models are called with the same API key on /v1/chat/completions, offer a 1,000,000-token context and 524,288 tokens per response, and take image and video. M3.1 Flash costs $0.15 / $0.015 / $0.60 at a single tier; M3 starts at $0.30 / $0.06 / $1.20 and doubles for prompts above 512,000 tokens.
- 1M-context Flash models: MiniMax, DeepSeek, Qwen and GLM - On LLMTR all four models have a 1,000,000-token context and are called with the same API key on /v1/chat/completions. Their prices are close; the differences are in the output limit per response, video input, reasoning control, JSON support and DeepSeek's weekday peak-hour price.
- MiniMax M3.1 Flash vs Haiku 5.5, GPT-6 Luna, Gemini 3.8 Flash - On LLMTR all four models are called with the same API key on /v1/chat/completions. For prompts up to 100,000 tokens Claude Haiku 5.5 and GPT-6 Luna cost less; once a prompt passes 272,000 tokens MiniMax M3.1 Flash moves ahead, because its price does not change up to 1,000,000 tokens. Video input is on MiniMax M3.1 Flash and Gemini 3.8 Flash.
- Which MiniMax model? M3.1 Flash, M3, M2.7 and M2.5 - On LLMTR six MiniMax text models are called with the same API key on /v1/chat/completions. M3.1 Flash and M3 offer a 1,000,000-token context and image and video input; M2.7 and M2.5 are text models with a 204,800-token context. The Highspeed versions give faster output at twice the input and output price.
