the answer engine is selling decisions now. perplexity shipped a decisions api plus an open 27b model, pplx-decider-v1-27b, on oct 1, built on qwen3.8 and apache-licensed.
search's endgame is not finding information, it's not having to decide.
Context
Perplexity released a Decisions API with its first decision model, pplx-decider-v1-27b, on October 1. Perplexity's docs describe a decision model as one that reads text and images like a multimodal model but returns a structured choice that software can use directly.
The Hugging Face card says it is fine-tuned from Qwen3.8-27B, and a model directory lists an Apache 2.0 license.
Naming: the current API docs show a pplx-decider-v1.1-27b model in the example request, so the version may have moved since launch.
Benchmark results on the model card were measured through Perplexity's API and are the vendor's numbers.
'Search's endgame is not having to decide' is the author's opinion.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
