Mixlayer is an inference platform for open source AI models. We expose an OpenAI-compatible REST API, so you can drop Mixlayer into most existing applications by swapping the base URL and API key.

  -H "Authorization: Bearer $MIXLAYER_API_KEY" \
  -d '{"model": "qwen/qwen3.5-4b-free", "messages": [...]}'
