Choosing a model
What the model picker shows you, why some models are greyed out, and how to search a catalogue of hundreds with filters.

Click the model name beside the prompt box, or open Settings → Model.
This page is about the coding agent's model picker. For choosing a model when calling an AI tool over the API, see Choosing a model.
What you are looking at
The list is everything your workspace can call right now — nothing is bundled into the extension. That includes models you added yourself in the dashboard and any unlocked by your own provider keys. Add a model at midnight and it is in the picker on the next refresh, with no extension update.
Each row shows the context window, whether it caches, whether it handles images, and the minimum plan.
Searching
Free text matches the model name, vendor and description. An exact or prefix match on the name always wins over a fuzzy one, so typing claude-opus gives you that model rather than something whose blurb mentions it.
Filters narrow structurally:
| Filter | Example | Matches |
|---|---|---|
vendor: | vendor:anthropic | Models from one vendor |
tier: | tier:premium | economy, balanced, advanced, premium |
ctx: | ctx:>200k | Context window, with > >= < <= and k/m |
tools: | tools:yes | Proven tool calling |
vision: | vision:yes | Accepts images |
cache: | cache:yes | Supports prompt caching |
plan: | plan:pro | Available on that plan |
Combine freely: vendor:anthropic ctx:>200k cache:yes.
Why some models are greyed out
A model that cannot drive an agent is shown disabled with the reason, not hidden. A missing model looks like a broken product or a billing problem; "no tool calling" answers the question in place.
The usual reasons:
- No tool calling — it can chat but never calls a tool, so the agent loop stalls with no error.
- Tool calling unverified — nobody has run this model through us. Common for bring-your-own-key models.
- Context too small — it cannot hold an agent prompt plus your files.
Capability flags come from real calls, not from vendor documentation. A model marked as supporting tools has demonstrated it.
Scrolling
The list loads more as you scroll, and says how many of the total you are seeing. Nothing is hidden — keep scrolling to reach the end of the catalogue.
