What you'll do
Use the model selector to choose between available models so you get the right balance of speed, depth, and data-residency for each task.
Open the model selector
Click the model name displayed to the left of the Agent / Plan toggle in the composer. A dropdown lists every model available on your plan. The currently active model has a checkmark.
You can change the model at any point in a thread — including mid-conversation. The new model applies to the next message you send; earlier turns are unaffected.
Reasoning vs latency
Models fall roughly into two tiers:
- Larger / reasoning models — deeper analysis, longer chains of thought, better for complex planning, code review, research synthesis, or anything where correctness matters more than speed. Expect slightly longer response times.
- Smaller / fast models — near-instant replies, ideal for quick rewrites, short summaries, simple Q&A, and conversational back-and-forth where depth isn't the priority.
A good rule of thumb: start with the default model. Switch up when an answer feels shallow or misses nuance; switch down when you just need fast iteration.
Region & privacy
Some plans offer regionally-scoped models that process and store data in a specific geography (for example, EU-only). If your team has data-residency requirements, these models appear with a region label in the picker.
Selecting a regional model applies only to the current thread. If you need every thread to use a specific model by default, ask an admin to configure the org default in Settings → AI.
It persists per thread
The model choice is saved with the thread. If you close and reopen a thread, it continues using the model you selected. Starting a new thread resets to your org's default.
Not sure which to pick? The default model is tuned to balance reasoning and latency for most everyday tasks. You only need to switch when you have a specific reason.
