Source: Perplexity.Perplexity has announced hybrid compute for Personal Computer on Apple silicon Macs. Personal Computer already combined cloud-based Computer tasks with access to local files and apps, but its AI processing was primarily cloud-based. Recently, Perplexity also introduced Portable Computer, a local-first version of Computer that can escalate work to the cloud with a user’s permission.Hybrid compute approaches the problem from a different direction. Tasks start in the cloud but if a new local classifier detects potentially sensitive information, the user is alerted and asked whether they want to route it to a local model, although users also have the option to let the flagged data be used by a frontier cloud-based model. Gemma E4B, Qwen3.6 35B-A3B, and a Perplexity post-trained version of Qwen3.6 35B are available at launch for that local work, with more models to come in the future.Tasks that don’t require sensitive information are handled in the cloud by frontier models that also orchestrate the cloud and local tasks. Users select the cloud orchestrator and Perplexity chooses the helper frontier models used.Another key feature is that hybrid compute works with tasks begun from an iPhone or iPad, too. Those devices could already kick off a session, but now they can also run tasks that use sensitive information locally if your Mac is turned on and running Perplexity.Yesterday, I got a demo of the feature that walked through three scenarios:an attorney researching a legal brief, with sensitive client data on their Mac, allowing them to update it locally,an analyst using web-based data to update a confidential slide deck for a presentation about a company’s financials, anda small business owner kicking off pricing research from her iPhone that was combined with private pricing data for her business that never left her Mac.I haven’t tried hybrid compute myself yet, but if it works as advertised, it’s a big step forward for Perplexity, and one that a lot of its competitors are also chasing. AI agents are only as good as the tools and data to which they have access. Tool calling has been a big focus over the last year and more, but data privacy is an equally important issue that needs to be solved before more companies, especially those in regulated industries, adopt agentic tools like Personal Computer. It’s good to see Perplexity tackling this head-on.
