Qwen3 introduces hybrid thinking AI with powerful reasoning capabilities, supporting 119 languages and featuring MoE architecture for unprecedented efficiency. (Qwen3采用混合思维AI，具备强大的推理能力，支持119种语言，并采用MoE架构实现前所未有的效率。)

After 8 months building RAG systems for two enterprises (9M and 4M pages), we share what actually worked vs. wasted time. Key ROI optimizations include query generation, reranking, chunking strategy, metadata injection, and query routing. 经过8个月为两家企业（900万和400万页面）构建RAG系统的实战，我们分享真正有效的策略与时间浪费点。关键ROI优化包括查询生成、重排序、分块策略、元数据注入和查询路由。

English Summary: The article critiques DSPy as a cargo-cult approach to LLM optimization that treats models as black boxes and relies on random prompt variations rather than scientific understanding. It contrasts this with genuine research into mechanistic interpretability and mathematical analysis of transformer architectures. 中文摘要翻译：本文批判DSPy框架将LLM视为黑箱，依赖随机提示变异的伪科学优化方法，对比了真正研究机构对Transformer架构的机制可解释性和数学分析的科学探索。

This article explains why enterprises that optimize LLM outputs will struggle to disclaim responsibility for consumer harm caused by misstatements, even where models remain third-party and probabilistic. (本文阐述了为何企业即使在使用第三方概率性模型的情况下，也难以对因LLM输出错误导致的消费者损害免责。)

English Summary: Researchers at Sakana AI have developed 'universal transformer memory' using neural attention memory modules (NAMMs) to optimize LLM context windows by selectively retaining important tokens and discarding redundant ones, reducing memory usage by up to 75% while improving performance on long-context tasks. (中文摘要翻译：Sakana AI研究人员开发了“通用Transformer记忆”技术，利用神经注意力记忆模块（NAMMs）优化LLM上下文窗口，选择性保留重要标记并丢弃冗余信息，在长上下文任务中提升性能的同时减少高达75%的内存使用。)
