More about mistral-small-3.1-24b-instruct

Mistral Small 3.1 (24B) is Mistral AI's latest mid-size model, hosted on Cloudflare's global edge network for low-latency inference.

Runs on Cloudflare's shared 10,000 Neurons/day free pool and uses Cloudflare's native API format rather than the OpenAI SDK. Best for developers already in the Cloudflare ecosystem or those evaluating Mistral's small-model performance.
