What is Mistral Medium 3.5?
Mistral Medium 3.5 is Mistral AI's first flagship merged model, a dense 128B large language model. It is designed to handle instruction-following, reasoning, and coding tasks within a single set of weights. This model features a substantial 256k context window and supports multimodal input, accepting both text and image data to produce text outputs. It serves as a successor to previous models like Mistral Medium 3.1, Magistral, and Devstral 2, offering improved performance across its unified capabilities. A key feature is its configurable reasoning effort, allowing the same model to adapt from quick chat replies to complex agentic runs by adjusting compute per request. The model also incorporates a vision encoder trained from scratch to effectively handle variable image sizes and aspect ratios. It is released under a Modified MIT License, permitting commercial and non-commercial use with specific exceptions for companies exceeding certain revenue thresholds.
