# Choosing a model

> The Select model picker, what the capability marks and the EU badge mean, and which models your workspace offers.

Every chat runs on one model, and you choose which. The picker sits along the bottom edge of the
composer, labelled **Select model**.

## Reading the picker

Open it and each entry shows three things.

| What you see           | What it means                                                                                                 |
| ---------------------- | ------------------------------------------------------------------------------------------------------------- |
| The model name         | For example *"GPT-5.6 Sol (High)"*. The part in brackets is how hard the model is asked to think.             |
| A row of brain marks   | Capability, out of three. Hover for *"Capability: 2 of 3"*. Fewer marks means faster and lighter, not broken. |
| A blue circle of stars | *"Hosted in the EU"*. That model's requests run on EU infrastructure.                                         |

More capability is not automatically better. A higher setting spends longer reasoning before it
touches your deck, which is worth it for a dense slide built from a source document and wasted on
"make this heading shorter".

<Tip>
  Start on your workspace's default. Move up a level when a slide keeps coming out under-thought
  (wrong emphasis, missed constraint) rather than when it merely looks wrong, which is usually a
  prompting problem.
</Tip>

## The choice is per chat

Your pick is saved against the chat you are in, not globally. Open a second chat and it starts
from the default again.

You can switch at any point, including mid-conversation. The chat keeps its history; the next
turn runs on the new model.

## What is in the list

The picker's contents come from how your workspace is set up, not from your account. An admin
chooses the provider under [Model providers](/admin/model-providers).

<Tabs>
  <Tab title="Default and OpenAI">
    | Model                | Capability |
    | -------------------- | ---------- |
    | GPT-5.6 Terra (High) | 1          |
    | GPT-5.6 Sol (Medium) | 2          |
    | GPT-5.6 Sol (High)   | 3          |
  </Tab>

  <Tab title="AWS Bedrock">
    | Model             | Capability |
    | ----------------- | ---------- |
    | Claude Opus 4.6   | 3          |
    | Claude Sonnet 4.6 | 2          |
    | Claude Haiku 4.5  | -          |
  </Tab>

  <Tab title="Google AI Studio">
    | Model                           | Capability |
    | ------------------------------- | ---------- |
    | Gemini 3.6 Flash (Medium)       | 1          |
    | Gemini 3.6 Flash (High)         | 1          |
    | Gemini 3.1 Pro Preview (Medium) | 2          |
    | Gemini 3.1 Pro Preview (High)   | 2          |
  </Tab>

  <Tab title="LiteLLM">
    A LiteLLM proxy offers the same list as the default setup (GPT-5.6 Terra and Sol), routed
    through your company's proxy URL. Each of those models has to exist on the proxy's model list
    for it to work.
  </Tab>
</Tabs>

## Errors you can hit here

<AccordionGroup>
  <Accordion title="The selected model isn't available on your LiteLLM proxy" icon="plug-circle-xmark">
    The full message: *"The selected model isn't available on your LiteLLM proxy. An admin needs
    to add it to the proxy's model list."* The picker offers it, but your proxy does not route it.
    Pick a different model to keep working, and ask an admin to add it.
  </Accordion>

  <Accordion title="The AI provider rejected your API key" icon="key">
    *"The AI provider rejected your API key. Please check that your key is valid in settings."*
    The key your workspace configured has been revoked, mistyped, or lacks access to that model.
    Nothing you can fix from the chat. It is a [provider settings](/admin/model-providers) job.
  </Accordion>

  <Accordion title="Your organization requires an API key" icon="lock">
    *"Your organization requires an API key, but none is configured. Add one in settings to
    continue."* Your workspace is set to bring-your-own-key and no key is in place yet. If you are
    an admin, **Open settings** takes you there; if not, ask one.
  </Accordion>
</AccordionGroup>

Two more you may see, neither specific to the model you picked: the provider's quota has been
exceeded, and the provider is rate limiting requests. Both are worth a retry a moment later
before anything else. For hitting your workspace's own monthly spend cap, see
[Usage and limits](/admin/usage-limits).
