pplx-decider-v1.2 ranks #2 overall on the Hugging Face Decision Index.
Open weights for both models are available to run on your own infrastructure.

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 scores the highest on Decision Bench for accuracy, with the lowest cost.
It reached 94.5% accuracy across 1071 cases at $0.017 per 1,000 decisions.

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.
You can now build custom reusable agents in the Perplexity Agent API with Profiles, Skills, and managed connectors.
Configure an agent once in the API Portal and reuse it across applications and workflows.
Fast Search is now the default search in Hermes Agent for Nous Portal subscribers.
It’s built for agentic tasks, with single-search-call latency of 160 ms at p50 and 230 ms at p95.

A new Perplexity Search SDK cookbook is live.
The recipe fans out focused searches, filters results to official docs, extracts relevant passages, and writes a source-linked brief for your coding agent.
