Mistral-7B-Instruct-v0.3 — Free API

What is Mistral-7B-Instruct-v0.3?

Mistral 7B Instruct v0.3 is a compact, efficient open model available free on Hugging Face's Serverless Inference API. At 7B parameters, it is lightweight and fast, best suited for straightforward chat, text classification, and simple generation tasks. Context is limited to 32K — adequate for conversations and short documents but not long-form analysis. Uses Hugging Face's native API format (not OpenAI-compatible); rate limits are approximately 1,000 requests per day. Registration required.
