Together AI→Fireworks AI
On 2026-07-15, ChatGPT changed its #1 recommendation for best fine-tuning platform — dropping Together AI from the top spot in favor of Fireworks AI. The previous #1 had held since 2026-07-14.
“Best overall managed stack for open-weight models, combining SFT, DPO, and reinforcement fine-tuning with LoRA or full-parameter training, strong deployment performance, and useful multi-LoRA serving; near-tied with Together AI, but broader post-training depth wins.”— ChatGPT
