MiniMax M3.1 Flash now available on AI Gateway for free

Vercel's AI Gateway is offering MiniMax's open-weight multimodal MiniMax M3.1 Flash model for free until Oct 20, but only when MiniMax itself serves the request, which developers can force by sorting providers with the `order` option in the gateway's provider options. MiniMax M3.1 Flash carries a 1M-token context window for long documents and multi-step agent sessions, and MiniMax reports improved results over earlier MiniMax models on complex agentic tasks, coding (application development, frontend interactions, targeted bug fixes, component tests) and cybersecurity. After the offer ends, pinned requests bill at MiniMax's standard rate, and the model is callable via the AI SDK, Chat Completions, Responses and Anthropic Messages APIs or a connected coding agent using the model name `minimax/minimax-m3.1-flash`.
