法新社记者：特朗普称双方达成了“极佳的贸易协议” 在进行了至少十分钟且避开随行记者团视线的谈话后，特朗普与习近平继续散步。 特朗普说：这些是任何人所见过最漂亮的玫瑰。 当随行记者询问特朗普是否享受此次访问时，他没有回答，而是竖起了大拇指。中方工作人员表示“不接受提问”。 两国领导人穿过一条带有绿色柱子的加盖走廊，廊上的拱门绘有鸟类和中国传统山水画。他们朝着举行“友谊合影”的小广场走去，该地点同样处于随行记者的视线之外。 现在他们身处一座华丽的亭子，特朗普与习近平已经就座。美国国防部长赫格塞斯、国务卿鲁比奥和财政部长贝森特也在现场。 习近平通过翻译介绍该建筑群的历史。他表示将向特朗普赠送玫瑰花种。 特朗普表示，他们已经达成了“极佳的贸易协议”。 （照片由摄影记者Evan Vucci拍摄，他也是特朗普遇刺后振臂高呼照片的拍摄者）

Toto 2.0：开源时序预测模型 包含4M到2.5B五个大小的模型，Scaling Law有效，参数越大效果越好。在BOOM、GIFT-Eval、TIME评测上排名第一。 时序预测模型，可以理解为根据过去的数字推测未来的数字，跟预测相关的都可以使用。 模型：

Stop testing and rewriting prompts manually! Most teams run evals, look at failures, guess what's wrong, rewrite the prompt, then repeat. It's slow and you never know if your rewrite actually fixes the root issue. The better way is evolutionary optimization. Instead of manual rewrites, you use genetic algorithms to analyze eval feedback and rewrite prompts automatically. The algorithm maintains diverse prompt candidates that excel at different problem types, not just one "best" version. DeepEval does this using GEPA - Genetic Evolution with Pareto Selection. You provide a prompt template, test cases, and metrics to optimize for. The optimizer handles the rest. Here's how it works: It splits your test cases into validation and feedback sets. The validation set scores every prompt fairly. The feedback set provides training signals for mutations. Then it starts evolving. It selects a parent prompt, runs it on a minibatch of test cases, collects metric feedback on what failed, and uses an LLM to rewrite the prompt addressing those issues. If the rewritten prompt scores better, it gets added to the candidate pool. After several iterations, it returns the highest-scoring prompt. Key capabilities: • Works with 50+ built-in metrics - answer relevancy, hallucination, bias, task completion, and more. • Supports multi-objective optimization - optimize for multiple metrics simultaneously without forcing tradeoffs. • Configurable iterations and minibatch sizes - control search thoroughness and compute cost. The best part? It's 100% open source. Link to DeepEval in the comments!
