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)
