The honest brief
Predibase
Its open-source LoRAX engine serves dozens of fine-tuned LoRA adapters on one GPU, so shipping many per-task fine-tunes stays cheap.
- Fine-tune + serve in one place
- End-to-end RFT workflow
- Many adapters per GPU (LoRAX)
- SaaS or your own VPC
- Enterprise-priced
- Now tied to Rubrik's roadmap
- Open-source models only
Tinker
Hands you the training loop itself — forward_backward and sample primitives — rather than a one-click fine-tune form, with distributed GPUs managed for you.
- Exposes forward_backward, optim_step, sample
- Large MoE models supported
- Downloadable trained weights
- No GPU infra to manage
- LoRA-based only (no full fine-tune)
- Usage-based, no free tier
- Python SDK only
When to pick which
Both cover Fine-tuning / training.
Pick Predibase if you need Model inference / serving.
- Model inference / serving (primary capability)
Pick Tinker if you need Multi-model access.
- Multi-model access (secondary capability)
Tinker leans on Fine-tuning / training as a headline capability; Predibase treats it as secondary.
- Fine-tuning / training (primary capability)
