Choose a surface

Use the highest-level surface that gives you the control you need.

Chat

Use Chat for questions, explanations, and short drafts. It uses bounded host-side capabilities and does not give you general workspace compute.

Work

Use Work for multi-step outcomes that need files, commands, durable outputs, or approvals. Work adds managed compute and a reviewable execution trail.

Models API

Use the OpenAI-compatible Models API when an application needs to call a hosted model directly.

Sandboxes

Use the Sandbox SDK when you need isolated commands, files, processes, previews, or durable runtimes under your application's control.

Desktop & Open Source

Use Desktop & Open Source to keep local projects close to the work, evidence, Tasksets, and evaluation workflows that improve them.

Next: Create an API key.
