Parallel Decisions API searches the live web for typed answers at $1 per 1,000 calls. See how citations, refusals and its benchmark work.
By Parallel · Released 25 Oct 2026
A decision engine that searches the live web before it answers. You send typed questions about a company, product or policy, and one call returns typed answers with probabilities (or a refusal) plus a shared list of the web pages it used, so it can answer things a model only knows from training data cannot, such as whether a company has an open job right now.
Parallel Decisions API: A decision engine that searches the live web before it answers.
Parallel Decisions API: Published price (vendor-reported): $1 per 1,000 calls (as of 25 Oct 2026)
Parallel Decisions API searches the live web and answers typed questions about the shared state. That suits facts that can change, such as whether a company offers a product or has an open job. The response can contain a refusal, which calling code must handle. Citations belong to the whole request, rather than to individual answers.
Compare with OpenAI Decisions API · Live web facts use case
Parallel lists $1 per 1,000 calls and 5,000 free requests to start. Several questions can share one state in one paid call. This is a per-call price; hosted models priced by input tokens use a different billing unit.
Decision model pricing · Compare decision models
Parallel reports 76.22% on its own 300-question PWS-Decisions benchmark. It used live search, while the compared decision models had no web access or supplied external context. The benchmark tests current web facts; it does not establish a lead on questions where every model receives the same evidence. Dataset terms prohibit redistribution.
Parallel launched Decisions Fast on OpenRouter on 6 Nov 2026 with a seven-day free promotion. On 7 Nov the decisions inventory lists parallel/decisions-fast:free with 32,000 tokens and text input; the unsuffixed route present in the morning snapshot is absent. An inventory omission does not prove that requests to that route fail. The promotional zero price is separate from the direct API's recorded per-call rate. Parallel says up to 100 related questions can share one search call.
