Introducing pplx-embed-v2-context: open-weight vision-language embedding models in 9B and 0.6B.
Both return one int8 vector per document, or one per chunk that sees the whole document.

You can now run pplx-decider-flash-v1.2 locally on your Mac, without an API key.
Decider for Mac is an app that runs the 4B decision model on device. Ask a question about text or an image and get a probability back, all on your machine.

Our next generation of open weights multimodal decision models comes in two sizes, pplx-decider-v1.2 and pplx-decider-flash-v1.2.
Text and vision scores improve. Inference is up to 5x faster: all questions in a request run in one pass.
Flash is the top 4B on the Decision Index.

pplx-decider-v1.1-27b is now available on OpenRouter.
Perplexity Decider v1.1 is now on OpenRouter
@perplexity_ai's open-weights multimodal decision model takes text, JSON, or images and returns typed answers with probabilities
$0.02/M input. Output is free

pplx-decider-v1.1-27b, our updated open weights multimodal decision model, is now available.
It scores the highest on the new @huggingface Decision Index 0.3 benchmark. pplx-decider-v1.1-27b costs half as much as v1, at $0.02 per million input tokens.

We're looking forward to working with the new @NVIDIA Vera CPU on SPACE.
It was great to have the @NVIDIA team stop by and drop off their new Vera CPU.
A lot of what we’re building depends on agents being able to run more capable code environments, safely and reliably. We’re excited to test this work on Vera.

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.

Introducing Fast Search in the Perplexity Search API.
Fast Search runs on Photon, our new Rust-based retrieval and ranking service that we built with a small team of engineers and hundreds of agents.
It returns 95% of search results in 230 ms or less.

Connectors are now available in Agent API.
Connect your agents to GitHub, Slack, Google Drive, and Datadog without passing a server URL or token on every request.
API Group admins can connect each service once for all API Group members.

Introducing the Perplexity Search SDK.
It's an agent-first Python SDK that brings Perplexity's Search as Code approach to your applications.
Agents can fan out multiple searches, then filter, dedupe, and rank results in code.

Sonar is moving to the Agent API.
The Perplexity Agent API keeps grounded web search, and adds multi-step research, code execution, built-in tools, and access to multiple models through one API.
On BrowseComp and WideSearch, Agent API more than doubles the best Sonar score.

.@NVIDIA Nemotron 3.5 Lightning is now available in the Perplexity Agent API 🎉
An open 30B MoE model with 3B active parameters, built for the high-volume execution layer of always-on agents: tool calls, validation, and subagent work.
Pair Nemotron Lightning 3.5 with frontier models like Nemotron Ultra for planning, and let Lightning handle the volume.
