What changed from the first Codestral

Mistral reported a more efficient architecture and a revised tokenizer, with about twice the generation and completion speed of the original release. This is a provider comparison, not a guarantee for every editor or request.Codestral 2501 release announcement

Two published context figures

The current lifecycle page lists 128K context, while the launch benchmark table lists 256K. The measurement here follows the API model record. Neither figure establishes the size of a publicly downloadable checkpoint. The original codestral-2501 API is retired.Codestral 2501 model and lifecycle recordCodestral 2501 release announcement
