The week of 1 June 2026 brought agent-native search from concept to product. Three platforms shipped infrastructure built for AI agents, while UK regulators issued the first formal order addressing publisher rights in AI content extraction.

What Happened

1. Perplexity Launches "Search as Code"

Perplexity published a new search architecture on 1 June: AI models write their own Python retrieval pipelines, which execute in a secure sandbox instead of firing calls at a fixed API (Perplexity Research, 2026). The system claims an 85% token reduction on complex tasks and outperforms OpenAI and Anthropic on four of five benchmarks (Perplexity Research, 2026). It ships in the Perplexity Agent API and is now the default in Computer (The Decoder, 2026).

2. Microsoft Announces Web IQ at Build 2026

Microsoft launched Web IQ at Build on 2 June: AI-native grounding APIs that return ranked passages and evidence objects instead of links (Bing Blog, 2026). Microsoft reports sub-165ms P95 latency, 2.5x faster than competitors. It already powers grounding inside Copilot and ChatGPT's web responses, with enterprise access by waitlist (Windows Report, 2026; Search Engine Journal, 2026).

3. UK CMA Orders Google to Grant Publisher Opt-Out Controls

The Competition and Markets Authority ordered on 3 June that Google must let publishers withhold content from AI Overviews, AI Mode, and Gemini, with nine months to implement (CMA, 2026). Google also faces requirements to provide engagement metrics and ensure attribution links function (Bloomberg, 2026). The CMA called the order a world first. Further action on Google's search business is coming (GOV.UK, 2026).

4. Perplexity Expands Personal Computer Agent to Windows

Perplexity launched Personal Computer for Windows on 3 June, bringing its multi-model orchestration system to the world's largest desktop platform (Heise, 2026). The agent selects from over 20 AI models and accesses local files, apps, and web services, starting with Max and Enterprise Max subscribers (OpenTools, 2026). On 5 June at Computex, Perplexity also demonstrated hybrid local-server inference that routes workloads between device and cloud automatically (VentureBeat, 2026).

Why It Matters

Search is programmable infrastructure now. Perplexity's Search as Code and Microsoft's Web IQ both reframe search as a grounding layer inside agent pipelines (Perplexity Research, 2026; Bing Blog, 2026). Whichever company becomes the default grounding layer for third-party agents captures recurring usage outside the consumer search surface.

Google builds agents into its search product; Perplexity and Microsoft build search into agent products. Both converge on the same model: charging for the information layer that keeps agents accurate and current (Google, 2026). The race is for ownership of retrieval infrastructure.

The CMA's 3 June order is the first legal instrument compelling a platform to separate content rights from AI inference at scale (CMA, 2026). Nine months to implement, with further action signalled: the compliance window is closing. To see where your business stands inside AI search today, run your free AI Discoverability Score.

Who Wins / Who Loses

Winners

•

Enterprise AI developers: Two agent grounding APIs with documented performance metrics arrived in the same week (Bing Blog, 2026; Perplexity Research, 2026).

•

UK publishers: Opt-out rights and engagement data access are now legally enforceable (Bloomberg, 2026).

•

Perplexity: Three launches in four days: Search as Code, Personal Computer for Windows, and hybrid inference.

•

Microsoft: Web IQ repositions Bing as enterprise infrastructure beyond consumer search (Search Engine Journal, 2026).

Losers

•

Google: CMA compliance costs and publisher friction land as AI Overviews scales globally (CMA, 2026).

•

Traditional search APIs: Purpose-built agent grounding products expose the architectural mismatch of legacy keyword-and-link APIs.

•

Smaller publishers: Without technical teams to implement opt-out controls, most remain in AI summaries by default.

•

OpenAI: An estimated 250-500 million weekly ChatGPT searches (Digital Applied, 2026) but no agent grounding launch this week.

The One Thing to Remember

Search is now two products. One runs in browsers for humans; the other is an API layer returning passages and evidence for AI agents. Perplexity and Microsoft both shipped the second version this week. Publishers and brands built for the human version are in the wrong architecture. The gap widens every week.
