Codestral, the first code generation AI model from the Mistral AI team, empowers developers to write and interact with code through shared instructions and completion API endpoints. Trained on over 80 programming languages, including Python, Java, C, C++, JavaScript, and Bash, Codestral can perform coding tasks, generate tests, and utilize a middle-fill mechanism to complete portions of code. Codestral sets a new performance standard with its 32k context window, surpassing all other models on RepoBench, which is significantly larger than competitors' 4k, 8k, or 16k windows. It offers a dedicated API endpoint, codestral.mistral.ai, allowing users to integrate it into their IDEs using Instruct or Fill-In-the-Middle routing and provides a free beta period of 8 weeks. Codestral is also integrated into popular application frameworks like LlamaIndex and LangChain, as well as development environments such as VSCode and JetBrains, enabling developers to generate and interact with code seamlessly within these platforms.
