Workbench

The Workbench lets you prompt base models in your browser without writing code. Pick a model and type a raw prompt to generate a completion, with the same sampling controls as the API.

You can also explore completions in two views:

  • 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.

Open Loom from the top nav. For Compare mode, use the Single / Compare toggle in any Workbench chat composer. Both are private to your account.
