Models and tool approval
Configure which models appear in chat, how tools run, and which model generates chat titles.
Open Settings → Models.
Pin models
Pinned models show at the top of the model picker in chat. Pin the models you use most often across providers.
Browse the full model catalog in the Models tab to find ids for newer releases.
Tool approval
Tool approval controls whether Agent mode asks before each tool call:
- Always ask — approve or deny run cell, edit file, terminal, and similar actions individually
- Auto-run — execute tools without per-call prompts
See Tool approval and compaction.
Title generation model
Orion generates short titles for new conversations using a separate title generation model. Pick a fast, inexpensive model here so chat titles stay cheap and responsive.
This is independent of the model you select for messages in the chat input.
Unavailable models
If a model is grayed out or missing:
- Confirm the provider is configured under Settings → Providers
- For local models, confirm the server is running and the model id is correct
- Pick a pinned model or another entry from the catalog
Workspace overrides
Project teams can override chat settings (including pins and title model) in <workspace>/.orion/settings.json. See Workspace settings.
