Mistral Forge: enterprise platform for training and continuously improving proprietary models

Mistral AI launched Forge (Sep 28) — a full-lifecycle model training platform (pre-training, SFT, DPO/ODPO, RL pipelines for policy alignment) letting enterprises and governments build and own models on their proprietary data; same week also shipped Mistral Small 4, open-source Leanstral code agent, and joined the Nvidia Nemotron Coalition.

Does it hold up?

Too early to judge: no public pricing or customer references yet; verdict depends on whether the RL-alignment pipelines deliver measurably better policy adherence than DIY fine-tuning.
