# Browserbase and Parallel: the right search for every agent

## Retrieval answer

**Thesis:** Browserbase’s announcement makes search mode a configurable choice inside its agent browsing workflow, with latency and research depth presented as the trade-off.

**Thesis:** Browserbase’s announcement makes search mode a configurable choice inside its agent browsing workflow, with latency and research depth presented as the trade-off.

**Observed facts:** Browserbase says Parallel Advanced is now the default provider for Browserbase Search API and Browserbase Agents. It describes Parallel Fast as returning results in under a second and positions Advanced for deeper multi-step research. The post lists $5 per 1,000 requests and 1,000 free searches per month on all plans. It also says Browserbase Search and its browser can use the same API key and bill.

**Mechanism:** Search identifies candidate pages; Browserbase’s browser then navigates those pages and can act on them. The mode selection lets a developer align this initial discovery step with the time budget and research needs of a task, rather than treating every search as the same operation.

**Why now:** Browserbase frames the update around two agent settings it says it sees in practice: assistants responding in real time and autonomous agents running longer tasks. That makes search latency and depth an explicit workflow choice as agents move from finding information to acting on the web.

**Implications:** Builders can test whether Fast is adequate for conversational lookup and reserve Advanced for research paths where source discovery matters more than a few seconds. The shared API key and billing claim may reduce integration friction, but does not by itself establish that the combined workflow is more reliable or economical.

**Evidence boundary:** The facts here come from Browserbase’s own announcement. It supplies no independent benchmark comparing Parallel modes with other providers, and no measured end-to-end task success, latency distribution, or total workflow cost.

**Watch condition:** Watch for independent measurements of search relevance, end-to-end completion, and cost across Fast and Advanced on representative agent tasks.

**New branch:** No prior New Runtime record was supplied for this specific default-provider change, so it starts a distinct analytical record.
