Perplexity Adds 'Deep Research in Computer' and a Microsoft Cloud Deal as Its Amazon Fight Escalates

# Perplexity Adds 'Deep Research in Computer' and a Microsoft Cloud Deal as Its Amazon Fight Escalates

Perplexity spent the last week of July doing two things at once: shipping a raft of upgrades to its agentic assistant, and leaning harder into a cloud alliance with Microsoft that reroutes the startup around the retail giant currently trying to block it in court. Together, the moves sketch out how Aravind Srinivas intends to keep his answer engine growing while a federal injunction hangs over its most ambitious feature.

The product news arrived through a dense changelog. Perplexity folded "Deep Research" directly into Computer, its agentic work environment, so a multi-step research run can be turned into a report, spreadsheet, presentation, dashboard, website, or workflow without leaving the thread. It paired that with a new command panel — type "/" to search across modes and skills before starting a task — plus thread forking, which lets users branch a follow-up question into a separate thread while keeping the artifacts and context of the original. Rounding out the release were improved inline confirmations and, aimed squarely at businesses, a Computer Analytics API and custom per-seat credit limits.

Those enterprise controls are not cosmetic. Deep Research in Computer routes subtasks across more than 20 frontier models, and metered credits burn fast when an agent is spinning up decks and dashboards autonomously. Analytics and hard credit ceilings are the guardrails Perplexity needs before IT departments will let the tool loose on real budgets.

The Microsoft lifeline

The infrastructure underneath that ambition increasingly runs through Redmond. Perplexity signed a three-year deal reported at roughly $750 million to tap Microsoft's Azure AI Foundry, the neutral-ground platform that lets customers run models from competing labs — OpenAI, Anthropic, and xAI among them — on optimized Azure hardware. For an answer engine that constantly swaps models behind a single query, Foundry is less a vendor than a menu.

"Our customers expect to use multiple models as part of any workload," Microsoft chief executive Satya Nadella said, noting that more than 1,500 Foundry customers had already run both OpenAI and Anthropic systems. That multi-model pitch is exactly what Perplexity is built on.

Crucially, the deal is additive, not a divorce. AWS remains what Perplexity calls its preferred infrastructure provider — Srinivas has said the company has committed "hundreds of millions" to Amazon's cloud — so the Microsoft agreement adds capacity and model access rather than replacing anything. But the optics are hard to miss: Perplexity is deepening its dependence on Amazon's fiercest cloud rival at the exact moment it is fighting Amazon in court.

The Amazon fight it is trying to route around

That fight is over agentic shopping. Amazon sent Perplexity a cease-and-desist letter on October 31, 2025, arguing its Comet browser was accessing Amazon's password-protected systems without authorization and causing "considerable harm." Perplexity refused to back down, publishing a defiant post titled "Bullying is not innovation."

The dispute hardened in March. On March 9, 2026, U.S. District Judge Maxine M. Chesney in San Francisco granted Amazon a preliminary injunction ordering Comet to stop shopping on Amazon, finding Amazon likely to prevail on its claim that Perplexity violated a roughly 40-year-old federal anti-hacking statute by accessing the site without permission. Perplexity appealed to the Ninth Circuit the next day, and the appellate posture has muddied enforcement — leaving the future of agents that act on a user's behalf, on someone else's platform, genuinely unsettled.

Why it matters

The three storylines are really one story about who controls the agentic web. Perplexity's Computer upgrades push it further into "do it for me" territory — the mode where an assistant navigates sites, fills carts, and completes tasks. That is precisely the behavior Amazon is suing to stop. Every improvement to Deep Research in Computer raises the stakes of the legal question underneath it: does an AI agent acting for a logged-in human have the right to be on a platform that does not want it there?

The Microsoft alliance is the hedge. By diversifying onto Foundry, Perplexity reduces its exposure to any single gatekeeper — cloud or retail — that could throttle it. And Foundry's model-agnostic design mirrors Perplexity's own philosophy, making Microsoft a natural partner in a market where OpenAI, Google, and Amazon all have reasons to squeeze a scrappy competitor. Cloud neutrality, it turns out, is a competitive weapon.

What to watch

Watch the Ninth Circuit. A ruling that upholds Amazon's injunction would ripple across every agentic-commerce startup and force a redesign of how Comet interacts with retailers; a reversal would embolden the whole category. Watch whether Perplexity's enterprise controls — the Analytics API and credit limits — translate into named corporate customers, the metric Srinivas himself says will decide the AI race. And watch how far the Microsoft relationship extends: if Foundry access widens, the AWS-preferred framing may quietly invert, turning a defensive hedge into Perplexity's primary bet.
