MiniMax

Free API usage
OpenRouter currently provides a free MiniMax M3 endpoint under the model ID minimax/minimax-m3:free.
Both prompt and completion tokens are priced at $0, with a 1,048,576-token context window.
The catch is that OpenRouter's free endpoints are rate limited, so this is more useful for testing, personal projects, and lighter workloads than guaranteed high-volume production use.
The free endpoint currently supports text, image, and video input, plus function calling.
How to Claim this Deal

1. Open the MiniMax M3 Free page (openrouter.ai).
2. Sign in to OpenRouter and create an API key.
3. Connect through OpenRouter's OpenAI-compatible API or a compatible application.
4. Set the model ID to minimax/minimax-m3:free rather than the regular paid minimax/minimax-m3 endpoint.
5. Send requests within OpenRouter's free-model rate limits.
