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.

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. pplx.ai/web-grounded-docs

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. pplx.ai/hf-embed-v2-9b pplx.ai/hf-embed-v2-0.6b

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.

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

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.
