Perplexity Decider Flash v1.2 Goes Open
Perplexity’s 4B open-weight multimodal decision model returns calibrated choices, scores, and yes/no probabilities instead of prose. Built for routing, moderation, ranking, and workflow gates, it supports 262K-token contexts and text-image inputs.
This is a compelling shift from chat-centric models toward compact, typed decision engines that application code can actually trust and control.
- –Distilled from Perplexity’s 27B decision model, Flash retains strong performance at roughly one-seventh the size.
- –Its separate decision head produces probabilities directly, avoiding fragile parsing of natural-language responses.
- –Apache 2.0 weights enable self-hosting, fine-tuning, and deployment in latency-sensitive pipelines.
- –Developers should benchmark question batching carefully: the model recommends one question per request except for tightly coupled multi-label decisions.
- –The custom noncausal runtime and roughly 9 GiB of BF16 weights make this less plug-and-play than a conventional Transformers model.
