Tinker
Train LLMs with
the Tinker API
A cloud training API that gives you full control over your data, algorithms, and models. Write training loops locally — Tinker handles the GPUs.
Training
LoRA Fine-Tuning
Model-agnostic LoRA training from 1B to 1T+ parameters — dense and MoE architectures, text and vision.
Algorithms
Full Control
SFT, RL (GRPO, PPO), DPO, distillation. Write your own loop or use cookbook abstractions.
Infrastructure
Remote GPU Clusters
Distributed training via API. Author code on a CPU machine — Tinker runs the compute.
