AI.

A collapsible panel for a model's thinking. It opens while the reasoning streams in with a shimmering label, times itself, then folds away into "Thought for 6s" once the answer starts, unless the reader opened it.

Shows a tool the model called: its name, a status from pending to done, the input and output as formatted JSON, and errors. Calls that need a human get Allow and Deny buttons and stay open until answered.

Citations for AI answers: numbered inline chips that preview their page on hover or focus, and a "Used 4 sources" line that opens into a list of links with their sites.

A searchable model picker grouped by provider, showing each model's context size, a short description and what it can do: read images, use tools, reason or read files. Fits in a prompt toolbar.
