DSPy 3.4.0 发布：引入 Jev 类型化决策与 ReAnchor 校准

AI 摘要

DSPy 发布 3.4.0 版本，通过 TypeSafe 客户端引入 Jev 集成，新增 Noul、Choice、Score 三种实验性决策类型，将概率证据带入普通 DSPy 签名。同时引入 ReAnchor 优化器，可依据程序指标校准布尔阈值、Score 切分和 Choice 权重。该版本还带来原生 LM 引擎、本地 CPython 解释器、异步 ReActV2 和版本化文档，并标记 3.5 为迁移截止版本。

# DSPy 3.4.0 DSPy 3.4 introduces **Jev integration through TypeSafe**, with three experimental decision types—`Noul`, `Choice`, and `Score`—that bring probability evidence into ordinary DSPy signatures. ReAnchor calibrates those decisions against your program's metric. This release also introduces native LM engines, a local CPython interpreter for trusted code, async ReActV2, and versioned documentation. ```bash pip install --upgrade "dspy==3.4.0" # Include the optional TypeSafe client f
