Workbench
The Workbench lets you prompt the base models straight from your browser — no code. Pick a model, type a raw prompt, and read the completion, with the same honored sampling controls as the API.
Two power-user views sit on top of the single-pane chat, built for base-model exploration:
- Loom — branch a prompt into a tree of completions: generate several continuations at once, pick one and keep going, backtrack to any point, and inspect per-token logprobs.
- Compare mode — run one prompt across several models (or the same model at different settings) side by side.
Loom is a first-class surface of its own — open it from the Loom link in the top nav. Compare mode lives inside any Workbench chat: flip the Single / Compare toggle in the composer. Both are private to your account.
