# Brain + Reflex: BrowserPair Task Intelligence

> Configure BrowserPair Brain and Reflex providers, fallbacks, trust thresholds, observations, and bounded task limits.

BrowserPair separates **planning** from **fast bounded execution** so routine browser work can stay responsive without giving the execution layer unlimited authority.

## Supported provider types

| Provider          | Brain | Reflex | Configuration                          |
| ----------------- | ----- | ------ | -------------------------------------- |
| Anthropic         | Yes   | Yes    | Model ID + credential                  |
| OpenAI            | Yes   | Yes    | Model ID + credential                  |
| Google            | Yes   | Yes    | Gemini model ID + credential           |
| TypeSafe          | No    | Yes    | Reflex-only                            |
| OpenAI-compatible | Yes   | Yes    | HTTPS endpoint + model ID + credential |

<Note>Provider credentials are encrypted in BrowserPair Cloud. The raw credential is not returned after creation.</Note>

## Configure routing

<Steps>
  <Step title="Add a provider">Open **Tools & settings → Brain + Reflex → Add model**.</Step>
  <Step title="Choose primary and fallback">Set a default Brain and optional fallbacks.</Step>
  <Step title="Set Reflex trust">Below the threshold, BrowserPair escalates rather than guessing.</Step>
  <Step title="Review observation policy">Control accessibility, DOM, screenshot, or combined observations.</Step>
  <Step title="Keep bounded limits">Use safe defaults unless a workflow actually needs more room.</Step>
</Steps>

## Observation modes

<Tabs>
  <Tab title="Lite">Small task-relevant semantic context.</Tab>
  <Tab title="Accessibility">Accessibility-oriented page structure.</Tab>
  <Tab title="DOM">Bounded DOM context when policy allows it.</Tab>
  <Tab title="Screenshot">Visual context without more authority.</Tab>
  <Tab title="Combined">Richer combined context when explicitly permitted.</Tab>
</Tabs>

<Warning>Richer observation is more context, not more permission.</Warning>
