Every Agent API effort level now costs less with the same or higher research quality.
Effort levels are bundled agent configurations, optimized for specific tasks.
A new ultra level is available for the most demanding, long-running requests.
pplx.ai/effort-levels
ultra runs three research agents in parallel and a fourth orchestrates, assigns tasks, and merges the findings.
Every child agent runs its own research loop with a separate context, using its own model, tools, and step budget.

Set effort to fast, low, medium, high, xhigh, or ultra to use the updated configurations in your workflow.

The Decisions API can now search the web before it answers.
A decision model returns a probability, but only knows what it saw in training, and your state. Add "mode": "web_grounding" and Fast Search runs one query per question, so pplx-decider-v1.2 answers from today's web.
When enabled, Fast Search results join state as evidence before the decision model answers. Pass a URL as the state to ask about a page.
Requests are $0.001 per search and $0.02 per 1M tokens.

Use web grounding to fact-check a list of claims, determine whether a pinned package has a newer stable release, or flag accounts with a new CEO, an acquisition, or layoffs.

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.
Read the paper, written with @turbopuffer: arxiv.org/abs/2610.38854
Both models also run in non-contextual mode: one embedding per document, no chunking.
On ViDoRe-V3 markdown, the 0.6B is the strongest sub-1B model, chunked (contextual) or unchunked (non-contextual). The contextual 9B with 128-token chunks is second only to voyage-context-4.

The 9B was trained only on text, yet it outperforms the leading dense retrievers on visual documents.
With two 1024d embeddings per page, it beats Nemotron-3.5-Embed-8B on ViDoRe-V3 with a 4x smaller index.

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.
pplx.ai/decider-for-mac
After a one-time 5.8 GB model download, the app serves the Decisions API at localhost:8080/v1/decisions.
Use it to label files, route messages, check screenshots, or run a pre-commit check, all without data leaving your Mac.
Requires a Mac with Apple silicon, macOS 13 or later, and 16 GB of memory.

The Batch API is now available on the Agent API.
Upload a JSONL file of up to 50,000 requests, create a batch, and download the results when it finishes.
pplx.ai/batch-api
Every batch request runs the full Agent API loop, which means built-in tools like web_search and fetch_url work inside a batch.
You can use any model from the Agent API models list.
pplx.ai/agent-models
Try the new cookbook tutorial to enrich a CSV of companies overnight.
One web-grounded Agent API request per row, written to JSONL, run as a batch, and joined back to your rows as enriched data.

pplx-decider-v1.2 is the highest scoring decision model on ClaimBench.
Try pplx-decider-v1.2 and pplx-decider-flash-v1.2 on OpenRouter or Perplexity API Console.
pplx.ai/openrouter-v1.2
Today we’re releasing ClaimBench, our new benchmark targeted towards decision models. It tests whether a model can tell if a financial document supports, contradicts, or doesn’t address a claim.
We evaluated 15 models on 1,960 claims paired with 10-K excerpts, with Decider V1.2 leading the pack of decision models.
