Search as Code means that search can be fully integrated end to end into any agent. Search with Perplexity is composable with any CLI or file format, meaning more efficient communication, fewer agent round trips, and improved latency/cost.
Introducing Search as Code, our new search architecture for AI agents. It writes Python that calls our search stack directly, instead of looping through function calls one at a time. Available in the Perplexity Agent API, and now default in Computer. research.perplexity.ai/artic…

I think it’s even simpler: the complacent designer has never been a valuable asset. The best designers are the ones who want to grow and learn. Long before the AI paradigm, designers who didn’t want to grow were getting PIP’d every month. Hiding in the dark corner of their company’s matrix, maybe making one rectangle a day… they were encouraged to grow their product sensibilities, to proactively solve business problems—and now the tools are just benefiting the people who are actively doing that. High agency has always been the most valuable archetype, and we are just seeing a higher delta between those who can and those who don’t want to.

There are two Designs. One of them is dead, the other is more alive than ever. 1. Design as the production of visual assets is over soon. This is unfortunately 90% of design jobs in industry. We won’t even need agencies to create design systems like Gokul thinks - they will get solved in the same breath as the rest of it 2. Design as a general method of problem solving is more exciting than ever thanks to AI dissolving the barrier to entry for most tools. The solution space for most designs have expanded dramatically for those with eyes to see It’s never been more exciting to be a designer, if you can let go of what design used to mean

GPT-5.5 is now available in Perplexity Computer as a more efficient, faster model for completing your tasks at lower cost. Claude Opus is still sometimes stronger on some of the hardest reasoning and coding tasks, so try both and prompt Computer to use a model when you need it.
GPT-5.5 is now available on Perplexity for Max subscribers. GPT-5.5 is also rolling out as the default orchestration model in Computer for both Pro and Max subscribers.

Latest research on grounded accuracy at improved latency and cost. Kudos to the Perplexity team, the Qwen team, and the open source community.
We've published new research on how we post-train models for accurate search-augmented answers. Our SFT RL pipeline improves search, citation quality, instruction following, and efficiency. With Qwen models, we match or beat GPT models on factuality at a lower cost.

Code is all you need: the new process for design and product at Perplexity
Over the past two months, my most impactful move as a design manager has been encouraging and supporting every designer to start building with Claude Code. Designers used to create a “source of truth” in Figma which was used for QA and accountability.. if anything was wrong, you’d point to the designs and say, “This is how it’s supposed to look.” The designers would take this artifact hand it off to engineers to build another “source of truth” on GitHub that would become the repo where other engineers can fork and build on top of. Now — the designer creates the source of truth on GitHub, and it’s closer to “the designs” because it is the designs. Less gets lost in translation, and everyone speaks in code. Figma remains useful for napkin sketches and quick visual experiments, but we are clearly moving beyond Figma as the primary document. The hardest part is getting set up—it’s daunting and scary leaving the things you love behind. People just need a little bit of emotional support to get started. But after taking the leap, everyone is feeling empowered and excited. They are all literally 10x’ing their productivity. The worst part is that engineers are a bit overwhelmed because they have way more PR’s to review.

Full circle: Perplexity started as a slackbot prototype in 2022 and we’re making our way back into multiplayer enterprise use cases: prototyping in public shared channels, sharing knowledge with AI, and responding to feedback in realtime by converting Linear tickets into code.

We are also bringing Computer to Slack. When we first tested Computer internally, it was as a Slack integration. We found it was a powerful way to share and collaborate on tasks. Now you can add Computer to any channel or DM.
