What is GPT-5.4 and what does native computer use mean?

GPT-5.4 is OpenAI's latest general-purpose model, released on 5 March 2026. Native computer use means the model can directly interact with software applications, including Excel and Google Sheets, without requiring a separate plugin or API bridge. This underpins the shift toward agentic AI workflows where models complete multi-step tasks autonomously.

What does 50% AI Overview coverage mean for my business?

It means that on approximately half of all US Google queries, users now see an AI-generated summary before any organic link. If your business relies on Google search traffic, you need to optimise for AI citation presence, not just keyword rankings. Brands that appear as sources within AI Overviews benefit from visibility even when users do not click through.

Why does the Perplexity CoreWeave deal matter for AI search?

Because it signals that AI search platforms are no longer treating infrastructure as a shared variable cost. By securing dedicated Nvidia GB200 clusters, Perplexity gains control over inference speed and quality at scale. Dedicated infrastructure typically means faster, more reliable answer generation, which directly affects the quality of AI search results.

How should businesses adapt to ChatGPT showing fewer links?

The shift away from links toward synthesised answers means citation within the AI response itself becomes more valuable than the click. Businesses should focus on getting their content cited inside AI answers rather than optimising purely for click-through. That means building structured, factual, citable content and ensuring your brand appears on the third-party sources AI models retrieve from.

What is FedRAMP 20x and why does government AI adoption matter for businesses?

FedRAMP 20x is the US government's security certification framework for cloud and AI services. Approval allows OpenAI, Google, and Perplexity to host AI directly on government systems and access federal procurement budgets. For businesses, government adoption validates AI search as stable enterprise infrastructure, accelerating private sector adoption across industries.

This Week in AI Search (w/c 02/03/26)

AI search hit two milestones this week.

Google triggered AI Overviews on half of all US queries. OpenAI released its most capable model yet, with native computer control.

This matters now.

What Happened

1. OpenAI launches GPT-5.4 with native computer use

OpenAI released GPT-5.4 on 5 March, its first general-purpose model with native computer-use capabilities (OpenAI, 2026). It is 33% less error-prone than GPT-5.2 and supports a 1 million token context window (TechCrunch, 2026). It is OpenAI's first model to ship with financial plugins for Microsoft Excel and Google Sheets.

2. Perplexity signs multi-year CoreWeave deal for AI inference

Perplexity announced on 4 March it will move inference workloads to CoreWeave's Nvidia GB200 NVL72 clusters (Axios, 2026). The deal covers Perplexity's Sonar model and Search API, with CoreWeave adopting Perplexity Enterprise Max internally (CoreWeave, 2026). CoreWeave shares jumped 5.7% pre-market on the news.

3. Google AI Overviews now triggers on 50% of US queries

AI Overviews grew 58% year-on-year and now appear on nearly half of all US searches (DemandSage, 2026). Ads within AI Overviews grew from 5% to over 25% of results in eight months (Search Engine Land, 2026). Commercial and navigational query coverage doubled in 12 months.

4. OpenAI, Google and Perplexity near FedRAMP 20x government approval

All three AI firms are close to approval for hosting AI directly on US government systems under FedRAMP 20x (Fast Company, 2026). Perplexity is already the second platform cleared, joining OpenAI which received authorisation in September 2025 (FedScoop, 2026). This unlocks billions in procurement for new entrants.

5. ChatGPT web search reduces link count in results

OpenAI's web search shifted this week to fewer traditional links and more synthesised answers (Optimixed, 2026). Publishers tracking ChatGPT referral traffic are already recording declines.

Why It Matters

AI search is no longer a supplement. It is the result. Google's 50% AI Overview threshold means most queries now return synthesised content before any organic link (DemandSage, 2026). Ad placements inside AI Overviews grew 394% in eight months (Search Engine Land, 2026). The ad economy is not dying. It is moving upstream.

The infrastructure layer is hardening. Perplexity's CoreWeave deal shows AI search firms now build dedicated inference capacity rather than relying on general-purpose cloud (Axios, 2026). Whoever controls inference controls search quality.

Government adoption changes the stakes entirely. FedRAMP approval for OpenAI, Google, and Perplexity is not a niche procurement story (Fast Company, 2026). It is the formal entry of AI search into national infrastructure. If you run a business, this changes everything about how customers find you.

Who Wins / Who Loses

Winners

OpenAI: GPT-5.4 leads in agentic capabilities with native computer use live for enterprise users (OpenAI, 2026).
Perplexity: The CoreWeave deal positions Perplexity as infrastructure-grade, not just consumer-facing (CoreWeave, 2026).
CoreWeave: The Perplexity partnership validates its GPU cloud model and drove a 5.7% pre-market stock gain (247 Wall St., 2026).
Government procurement teams: FedRAMP 20x gives agencies frontier AI access with discounted GSA OneGov pricing (FedScoop, 2026).

Losers

Traditional publishers: ChatGPT's fewer links and Google's AI Overviews at 50% penetration both reduce organic referral traffic (Optimixed, 2026).
AWS: Perplexity's shift to CoreWeave signals specialist AI cloud providers are winning inference contracts (Axios, 2026).
Mid-tier search platforms: FedRAMP approval tilts government spend toward the top three, shutting out smaller players.
Organic SEO: Queries triggering AI Overviews doubled in 12 months, cutting reach for traditional optimisation (Search Engine Land, 2026).

The one thing to remember

The interface between user and web is being replaced. Not redesigned. Replaced. When 50% of Google searches return AI answers and ChatGPT shows fewer links, "search, click, read" is over. The new model is "ask, receive." Stop measuring organic rank. Measure AI citation. The shift is not coming. It is here.
