Arkor
An alpha-stage TypeScript framework for fine-tuning open-weight LLMs with type-safe configs, a local Studio web UI, and managed GPUs.
Arkor lets a TypeScript or Node developer fine-tune open-weight language models the way they ship the rest of their application: type-safe configuration files instead of a separate config format, and a local Studio web UI for starting and watching training runs. A scaffolding command provisions a throwaway anonymous workspace with no signup required, so a real training run can start immediately, with an account claimed later if desired.
Starter templates pair a small open-weight base model with a curated public dataset so the first run finishes in minutes; example templates cover support-ticket triage, translation, and PII redaction, each producing typed structured output. Training, evaluation and serving are intended to live in the same codebase and review flow as the rest of a product.
It is an alpha project whose APIs may change without notice. It is written in TypeScript and licensed under MIT.
