# Fireworks AI Managed RFT paused, no new reinforcement fine-tuning jobs accepted

Markdown version of <https://harbyn.com/changes/fireworks/2026-10-01-managed-rft-is-paused-try-rl-on-the-training-api>.

Breaking change - Fireworks AI. high severity. In effect.

Managed Training no longer accepts new managed RFT jobs from the UI, firectl or the REST API; Fireworks points to RL on the Training API instead. Existing jobs stay visible and models already trained with managed RFT keep serving. 70 models that were tunable only through managed RFT can no longer be fine-tuned on Fireworks; inference on them is unaffected. Managed SFT and DPO are unaffected.
