I joined @perplexity_ai! I'll be working on making the web experience as great as it can be. Here’s a little video I made with Perplexity and Seedance

Introducing the Perplexity Decisions API. It's powered by pplx-decider-v1-27b, our multimodal decision model trained to output a probability distribution over a fixed set of answers instead of text. It costs $0.04/million input tokens and scores 85.71% across benchmarks.

Been a fun one to work on. Check it out now!
Introducing Automations in Perplexity Computer. Automations are for ongoing work. They can take action in response to event-based triggers or on a schedule. Automations work with your memory, skills, and connected apps like Slack, Gmail, Outlook, and Linear.

Our new paper shows how a modification of recursive depth (looping) for model growth can improve scaling exponents in pre-training! This means compute efficiency gains that increase with scale. arxiv.org/abs/2609.19107 w/@charllechen, @akshayvegesna, @industriaalist 1/7

We’re publishing research on how we built CobbleDB, our key-value database that serves web content for Perplexity search. Two engineers and a team of hundreds of proactive, always-on AI agents built the core infrastructure in two months.

Today we’re open-sourcing Lily, the local inference engine we built for hybrid compute in Perplexity Computer. Lily is specialized for Qwen3.6-35B-A3B on Apple silicon, built so on-device compute doesn’t bottleneck Computer tasks. Read more: perplexity.ai/hub/blog/optim…

Try out Perplexity Computer - it’s very good!
It is wild to me how slept on @perplexity_ai is by the market. I use Perplexity Computer constantly. Here is why: 1. I can share skills easily across my team easily in the cloud. 2. It is very good at model routing and selection and I have access to all the best models from all the model providers. 3. My perplexity computer tasks sync seamlessly between my desktop and cloud. 4. It is easy to build workflows from any task in computer for important reoccurring jobs. 5. Computer tasks process in the cloud so I don’t have to constantly have my desktop on and running. Now they have solved a critical security concern for many AI users. It isn’t perfect. I find that the design output for artifacts to be lower quality than using the same models in their own harnesses. Additionally it has bugs where tasks get hung up or take longer than they should to run.

It’s very possible to use only LLMs and still not make a slop website. Fable one-shotted this footer for me.
if you publish a LLM slop website it's an immediate turn off for me tbh

We're introducing hybrid compute for all users of the Perplexity Mac app. This will allow Computer to orchestrate local models that can run locally on Mac, particularly for agent steps involving sensitive and private files (eg your bloodwork, tax returns, litigation, etc).

perplexity is the best at search at any level of compute, agnostic of how much compute the competitors use.
Perplexity Search debuts on the Artificial Analysis Search Index, with all three context size variants taking top positions on the leaderboard The @perplexity_ai Search API comes with three context settings (low, medium, and high) that control how much extracted content each search result carries. We tested all three variants using our standardized methodology: the same model (GPT-5.6 Luna at medium reasoning), running inside Stirrup, our open-source agent harness, with tools for searching and fetching pages from the web. Only the provider behind the search tool changes. Key results: ➤ Perplexity Search (medium) scores 80 on the Artificial Analysis Search Index, ahead of the previous leaders, Parallel (advanced) and Brave Search (LLM context), at 75. The high and low variants score 79 and 77 respectively. Its lead is concentrated in BrowseComp results, with AA-Omniscience and DeepSearchQA scoring comparably to other leading providers ➤ Efficient search payloads: smaller overall search results mean the model reads less per task, so Perplexity has the lowest model inference cost per task of providers we’ve tested so far, ranging from $0.028 to $0.034 across the three variants vs $0.036 for the next lowest provider ➤ Total cost per task is ~$0.091 for the medium and high context variants, at mid-pack latency. For comparison, Parallel (advanced) costs $0.084 per task and Brave (LLM context) costs $0.13 per task

2 months ago, we crashed Jensen's board meeting to show him Perplexity running locally on DGX Spark 🤣 (lol im holding architecture diagrams like he's gonna look at em during a board meeting) Local AI used to be for enthusiasts. Folks were running tiny quantized models on underpowered hardware, getting a few tok/s. Exciting, but not practical. But now GLM 5.2 is my daily driver. Local AI hit an inflection point with frontier open source models like GLM 5.2, Deepseek v4 flash, and Nemotron + hardware powerful enough to run them, like DGX Spark and DGX Station. Developers are running fleets of agents. But there has yet to be a great personal agent experience for local AI. The current bottleneck is the know-how to set up inference and get meaningful performance out of it. I'm excited about Perplexity Portable Computer bc it’s an app that fully sets up a great local AI experience out of the box.
Meet Portable Computer, Perplexity's new local-first agent stack on NVIDIA DGX Spark. When running locally, Portable Computer offers one-click local inference setup and an optimized agentic experience for DGX Spark. Learn more and get started today: blogs.nvidia.com/blog/local-…
