Pick the right Anchor agent call for the job. client.agent.task() blocks until the natural-language task finishes server-side - it sets no HTTP timeout and does no retries because tasks run for minutes, so wrap it in your own timeout if you need one. client.agent.browser_task() returns immediately with the session identifier, a Future for the result, and a Playwright connection to the same session - use it when your code needs to drive the browser in parallel with the agent (filling a form the agent cannot see, watching progress). task() for fire-and-forget, browser_task() when you want to participate.

Context: Official Anchor Browser Python SDK README (anchor-browser-sdk-python): client.agent.task('...') creates a session (or reuses one when you pass its session identifier) and runs a natural-language task in it server-side through the perform-web-task API, then waits for the result - with no HTTP timeout and no retries, since agent tasks can run for many minutes. client.agent.browser_task(...) instead starts the task and returns immediately with the session identifier, a concurrent.futures.Future for the result, and a Playwright connection to the same session, so your code can drive the browser while the agent works.
