Mistral Large 3 Base

This is the pretrained base (non-instruction-tuned) variant of Mistral Large 3. For direct chat, agent, or Q&A use, reach for Mistral Large 3 Instruct instead — the base modelA model straight out of pretraining, before any fine-tuning for chat or specific tasks. Base models predict the next token but don't follow instructions well — they'll continue your prompt rather than respond to it. Most people never use base models directly; they use the instruct-tuned or chat versions built on top. Useful mostly for researchers and people doing their own fine-tuning. produces text continuations rather than answering questions, and behaves unlike a typical assistant out of the box. Base models are primarily interesting to teams planning their own instruction-tuning, reward-modeling, or domain-adaptation fine-tuning workflows. Same 675B MoEA model architecture that splits the model into many smaller specialized "expert" networks, only activating a handful per input rather than running the whole model every time. The practical effect: you get the knowledge capacity of a big model with the compute cost of a much smaller one. Mistral Large 3 and Mistral Small 4 are both MoE models. architecture, same 256K context, same Apache 2.0 license as the Instruct variant.
