On the agent side, that covers multi-step business processes and computer use that carries a task from one application to the next. For coding, MiniMax reports its best results on application development, particularly frontend interactions, targeted bug fixes, and component tests.\n\nThe free rate applies only when MiniMax serves the request. To make sure it does, sort the provider with `order` in the gateway [provider options](https://vercel.com/docs/ai-gateway/models-and-providers/provider-options). After the offer ends, pinned requests bill at MiniMax's standard rate.\n\nCall it through the [AI SDK](https://vercel.com/docs/ai-gateway/sdks-and-apis/ai-sdk), the [Chat Completions](https://vercel.com/docs/ai-gateway/sdks-and-apis/openai-chat-completions), [Responses](https://vercel.com/docs/ai-gateway/sdks-and-apis/responses), and [Anthropic Messages](https://vercel.com/docs/ai-gateway/sdks-and-apis/anthropic-messages-api) APIs, or a [coding agent](https://vercel.com/docs/ai-gateway/coding-agents) connected to AI Gateway. Use `minimax/minimax-m3.1-flash` as the model name:\n\nTo use it in Claude Code, Codex, Cursor, and more, install the latest Vercel CLI and run setup:\n\nThen select `minimax/minimax-m3.1-flash` in the agent. See the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents) for details.\n\nTry MiniMax M3.1 Flash in the [model playground](https://vercel.com/ai-gateway/models/minimax-m3.1-flash).\n\nAI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime.
