Perplexity

Perplexity is using an OpenAI model referred to as Astra to handle software changes, communications, and production monitoring with less frequent human check-ins. OpenAI published the case study; specific model specs and benchmarks have not been disclosed.

Perplexity's Mac app now supports Hybrid Compute, which starts tasks in the cloud and shifts sensitive steps to a local model running on-device. The feature requires Apple silicon with at least 24GB of unified memory and uses an open-sourced on-device PII classifier to mask private data before any cloud processing.

Perplexity has expanded its agentic Personal Computer feature from Mac to Windows 10 and 11, letting subscribers on paid plans automate multi-step tasks across local files, native apps, and cloud services like OneDrive and Outlook.

Perplexity has expanded its five-month-old Model Council feature to its Computer platform, allowing users to select between two and eight AI models—including options from OpenAI, Anthropic, Google, GLM, and Kimi—to independently tackle a query before a synthesizer model produces a consensus report. The feature, previously limited to enterprise and Max tiers, now serves Pro users at $20/month but runs on usage-based credit billing that can add up quickly for complex tasks.

Perplexity has launched Personal Computer for Windows, extending its agentic AI tool beyond Mac to work directly across local files, Microsoft Office 365, and the web. The tool is rolling out now to Max and Enterprise Max subscribers on plans starting at $200 per month.

Perplexity has released a major update to its Comet AI browser for iOS, adding eight new features including one-tap phone number actions, a redesigned iPad sidebar, and Finance Deep Dive analysis that opens as browser tabs. The update also fixes persistent bugs with recently closed tabs and deleted conversation threads.
