What is Pixtral 12B

Pixtral 12B is the first multimodal AI model launched by the French AI startup Mistral, capable of processing both images and text simultaneously. The model has 12 billion parameters, a model size of approximately 24GB, and is built on the text model Nemo 12B. It can answer questions about any number of images of any size. Pixtral 12B can perform tasks such as adding descriptions to images and counting the number of objects in photos. Users can download and fine-tune the Pixtral 12B model and use it under the Apache 2.0 license. Pixtral 12B will soon be available for testing on Mistral's chatbot and API service platforms Le Chat and Le Plateforme.
