Perplexity 发布 Decider v1.3 与 Decider Flash v1.3 决策模型
Perplexity 更新了自己的决策模型线，Flash 版从 60 分涨到 64 分，4B 小模型却进了前十。两款都开源且输入价格低到 $0.01-0.02/百万 token，做任务路由或工具调用选型的人可以直接对比成本榜。
Perplexity 更新了 v1.2 决策模型，发布 Decider v1.3 和 Decider Flash v1.3，在 Artificial Analysis Decision Index v2.1 上分别得到 70 分和 64 分。Decider v1.3 保持第 6 名，Decider Flash v1.3 升至第 10 名。
具体来看，Decider v1.3（27B）在 AA-Paperclip 上以 69 分排第 4，比 v1.2 提升 2 分；在 EvalSafe-O*NET-AA 上以 89 分排第 3，比 v1.2 提升 1 分。Decider Flash v1.3（4B）比 v1.2 提升 4 分，主要来自 AA-Symmetry 和 When2Call 各 12 分的提升。
两款模型都位于能力-成本 Pareto 前沿，每百万任务成本分别为 $68 和 $34，输入价格分别为 $0.02 和 $0.01 每百万 token。支持 256K 上下文、文本和图像输入，采用 Apache License 2.0 开源，通过 Perplexity 一方 API 提供。
