Mixtral-8x7B-Instruct-v0.1 — Free API

What is Mixtral-8x7B-Instruct-v0.1?

Mixtral 8x7B is Mistral AI's original MoE model, available free on Hugging Face's Serverless Inference API. With 8 experts routing to 2 active at any time, it delivers performance competitive with much larger dense models while keeping inference efficient. The 32K context window is its main limitation — adequate for conversations and short documents but not large-file analysis. Uses Hugging Face's native API format rather than the OpenAI SDK. Approximately 1,000 requests per day on the free tier; registration required.
