Perplexity

Claude Opus 5 is now available in Perplexity and Perplexity Computer.

We evaluated it against six other models on WANDR. It outperformed all but Fable 5, while being 57% cheaper.

Introducing SPACE, the sandbox platform behind Perplexity Computer.

It creates isolated environments for code, files, and long-running agent sessions.

SPACE has handled 100% of Computer production traffic since June.

We’re open sourcing WANDR.

WANDR is an internal benchmark we built and used for building deep and wide research capabilities inside Perplexity Computer.

🚢 What We Shipped

🧠 Brain - Self-Improving Memory - Computer builds a private context graph across your sessions, connectors, files, and past decisions, then refreshes it overnight. Every memory links to its source and is editable under Customize. In testing: +25% correctness, +16% recall, −13% cost on tasks with prior context.

⚡ Opus 4.8 Fast Mode - quicker responses for complex work without losing quality. Live on web, mobile soon.

🧭 Claude Fable 5 Orchestrator - pick Fable 5 to plan involved tasks, route subtasks to the right tools, and synthesize results - great for deep research and multi-source analysis.

🔀 Mid-Task Model Switching - change the orchestrator model between follow-up turns in the same task. Escalate to a stronger model, or drop to a cheaper one, without starting over.

🌐 Publish Your Website - ship sites built in Computer to a pplx.app link or your own domain via Vercel. Control access (you, specific people, your org, or public); admins can disable public publishing.

🗂️ Streamlined Homepage - Discover, Finance, Health, Patents, and Academic now live in a single menu.

📊 Usage Analytics by Model - see which models do your work across individuals and orgs, via analytics and the admin API. Available to everyone.

👥 Mac Account Switcher - switch between personal and work accounts in a click, with separate history and settings for each.

🏢 Private Company Research - Computer now pulls fundraising history, valuations, secondary pricing, and public marks (via Forge Global) - no setup or license needed.

Introducing Computer Analytics: You can now track credit spend across models.

Available now under Analytics in Account Settings for consumer and enterprise users.

GPT-5.6 Terra and Sol are now available in Perplexity and Perplexity Computer.

We're releasing a research preview of a new orchestrator model in Perplexity Computer.

The model is an adapted version of GLM 5.2, post-trained for the Computer harness. It delivers near-frontier performance at 0.344x of the cost of Opus.

Claude Sonnet 5 is now available in Perplexity for Pro and Max subscribers.

You can also select it as an orchestrator model in Computer.

Introducing Computer for Counsel.

Computer now connects the research databases, document tools, and matter-management systems lawyers use every day. Pull citable sources from midpage AI, LegalZoom, Docusign, NetDocuments, and more.

Available for all Pro and Max subscribers.

Introducing Brain in Computer.

Brain is a continuously learning memory system. Every task on Computer plugs into a context graph built by Brain.

It makes Computer more stateful with every run.

Available as a research preview for all Perplexity Max subscribers.

We're integrating Deep Research as a native skill inside Computer.

It now connects to the agent harness that powers Computer, with access to search as code generation, long running sandboxes, connectors, tools, and licensed data.

Available now to Pro and Max subscribers.

Claude Fable 5 is now available in Computer as an orchestrator model.

This is Anthropic's state-of-the-art model for long, complex tasks. Available only to Pro and Max subscribers in Computer.

We published new research with Harvard on the shift from chat interfaces to autonomous agents like Computer.

Over 3 months, findings show workers using Computer finish tasks in 87% less time at 94% lower cost than Search alone, with higher satisfaction.

We're open-sourcing the Unigram tokenizer we rebuilt to reduce CPU utilization by 5-6x.

Small rerankers and embedders run in single-digit milliseconds on GPU, making CPU tokenization a meaningful share of total latency.

We're open-sourcing Bumblebee, a read-only scanner for macOS and Linux.

It checks developer machines for risky packages, extensions, and AI tool configs.

Connected to Computer, it can trigger deeper scans whenever a new supply-chain risk emerges.
