Predibase
Alive. Prefer when you serve dozens of LoRA adapters on shared GPUs. Together/Fireworks remain simpler defaults for one-off SFT. Strengths: LoRAX multi-adapter serving (many fine-tunes / GPU); Active fine-tune + RFT product vs OpenPipe sunset; Strong open-model post-train story.
Strengths
- LoRAX multi-adapter serving (many fine-tunes / GPU)
- Active fine-tune + RFT product vs OpenPipe sunset
- Strong open-model post-train story
Weaknesses
- Pricing transparency uneven
- Smaller mindshare than Together/Fireworks
- Enterprise features sales-gated
Fireworks AI
Top pick for production open-model serving with real DX. Prefer over random GPU DIY when you want tokens not ops. Strengths: Fast production inference for open models; Strong fine-tune/post-train tooling; Good DX and model freshness.
Strengths
- Fast production inference for open models
- Strong fine-tune/post-train tooling
- Good DX and model freshness
Weaknesses
- Not a frontier closed-model source
- Unit cost can exceed pure discount hosts
- Enterprise features still maturing vs hyperscalers
