Overview

Mistral Small 3.1 (24B) is Mistral AI's latest mid-size model, hosted on Cloudflare's global edge network for low-latency inference. With 128K context, strong multilingual performance, and the efficiency of a 24B-parameter architecture, it is a practical choice for general chat, content generation, and text analysis where you want better quality than 8B-class models without the cost of 70B+ alternatives. 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.
