Search as Code: lower-cost, more reliable research in Computer

Search as Code optimizations are rolling out in Computer, routing search through a unified SDK-backed interface. Two update batches raised execution reliability from 81.9% to 92.6%; real-world workflows also showed higher user satisfaction at 8% lower per-task cost.

Try Search as Code in Computer to:

  • Research a market: “Compare the leading payroll platforms for a 200-person company, including pricing, integrations, and recent customer feedback.”
  • Verify a claim: “Find the primary sources behind this statistic and tell me whether the evidence supports it.”
  • Investigate a topic: “Map the latest AI data-center investments by company and cite every source.”

Connector approvals: pause actions before they run

Set a connector tool to Always ask when you want Perplexity to pause before it acts. Approve a single action, allow the tool for the rest of the thread, or deny it; recurring runs inherit thread-level grants.

Try connector approval controls to:

  • Review communication before it leaves your account: “Draft the customer update in Gmail, but always ask before sending it.”
  • Protect business records: “Prepare the new opportunity in Salesforce and wait for approval before creating it.”
  • Run recurring work with a standing grant: “Every Monday, collect this week’s calendar and CRM activity, then post the summary to Slack using the approval I granted for this thread.”

Perplexity Search SDK: write, rank, and filter search workflows in Python

The Python Search SDK lets agents fan out searches, then filter, deduplicate, and rank results in code. Install it as pplx-srch-sdk to build search workflows around your own application logic.

Try the Perplexity Search SDK to:

  • Install the SDK: Add pplx-srch-sdk to a Python environment and authenticate with your Perplexity API key.
  • Run parallel searches: Fan out multiple searches from one workflow, then collect the results in code.
  • Shape results in code: Filter, deduplicate, and rank returned results before passing them to your application or agent.
