An AI system based on the 27B parameter pplx-decider-v1 architecture delivers probability distributions over a fixed set of answers rather than prose. Perplexity open-sourced the multimodal model and made it available through its new Decisions API, which costs $0.04 per million input tokens and scores 85.71% across benchmarks.

CEO Arav Srinivas stated the tool performs better than Jev while operating at a fraction of the price. The release allows developers to integrate deterministic probability outputs into their applications as an alternative to traditional open-ended text generation.
