Mistral AI has been a leader in the code generation field and its latest model, Codestral 25.01, continues to push boundaries. This upgraded iteration promises even greater speed and capability, setting a new benchmark for coding models in its class. Described as lightweight, fast, and proficient across more than 80 programming languages, the original Codestral proved invaluable for developers tackling tasks like fill-in-the-middle (FIM), code correction, and test generation. The model quickly gained recognition for its ability to enhance productivity, serving as a reliable coding companion for developers worldwide. With a refined architecture and an upgraded tokeniser, Codestral 25.01 delivers code generation and completion abilities that are double the speed of its predecessor. For FIM use cases, Codestral 25.01 now leads the pack and is the definitive SOTA model in its weight class.
