一句话结论
在精确算术任务中，Agent和LLM架构相比传统计算不仅精度欠佳，延迟更暴增数万至百万倍，不宜将其作为“一刀切”的通用方案。
核心内容
- 确定性方法（本地函数、REST、SOAP、MCP）均实现100%准确率且延迟极低。
- 直接LLM推理最高准确率仅92.9%（延迟为基线的2.2万多倍）；Agent调用MCP工具虽可达99.9%准确率，但延迟高达基线的近100万倍。
- 提出架构决策框架（ADF），主张根据精度与吞吐量需求按任务类型选型，而非全盘依赖LLM。
方法与数据
- 基于保留运算符优先级的1,000个算术表达式基准，横向评测了原生Python函数、REST/SOAP/MCP微服务、Groq云端LLM、5个本地LLM及对应的MCP Agent系统。
价值判断
- 值得关注：量化揭示了Agentic AI在确定性算术任务中“高成本、低收益”的巨大性能代价。
- 可复用点：已开源的架构决策框架（ADF）及基准测试代码。
- 局限/待核查：实验仅针对受控算术任务，在融合复杂语言与推理任务的实际场景中仍需综合核查。
摘要
arXiv:2610.23921v1 Announce Type: new Abstract: There is growing interest in automating business activities with Agentic Artificial Intelligence (AI) due to latter's seeming ease of use. Never has it been easier, or costlier, to do less with more. However, little is known about when agents are preferable to established alternatives such as local computation, Representational State Transfer (REST), the Simple Object Access Protocol (SOAP), and the Model Context Protocol (MCP), particularly when development speed, performance, and operational cost are considered. We investigate this question using a controlled mathematical task that compares seven methods on a benchmark of 1,000 arithmetic expressions where semantics of operator precedence has to be preserved. We ran this setup across a native Function Calling baseline (Python library), REST, SOAP and MCP microservice architectures, direct responses from large language models (LLMs) using a Groq cloud API and five locally deployed Ollama models, and agentic systems in which five local LLMs invoke MCP tools. The deterministic methods achieve 100% accuracy with negligible latency. Direct LLM evaluation achieves at most 92.9% accuracy at over 22,000x the latency of a native function call. With MCP tools, the best agent reaches 99.9% accuracy, but incurs nearly 1,000,000x the baseline latency. These results demonstrate that LLMs approaches are poorly suited for exact arithmetic evaluation and motivate an informed architectural decision framework (ADF) for choosing an architecture based on accuracy and throughput requirements. We recognize that an actual interaction with an agent may span both reasoning and linguistic tasks. Hence our recommendation is to explore multiple architectural choices (based on task type) rather than one-size-fits-all solution (LLMs). Code is available at - https://github.com/Ritvik-G/adf/2.

一句话结论
FusionRare框架通过融合符号推理、深度学习与大模型等多范式AI，在罕见病诊断上刷新了SOTA表现，并显著提升了临床决策效率与医生信心。
核心内容
- 多范式融合机制：综合符号推理、深度模式识别、病例检索与大模型启发式推理，克服了单一范式面临的知识不全、黑盒缺乏解释性或数据泄漏偏见等局限。
- 诊断性能达SOTA：在严格防泄漏协议下，仅表型诊断和表型-基因联合诊断的宏平均Recall@1分别达到51%和79%，表现显著优于GPT 5.5、DeepRare等系统。
- 显著赋能临床决策：随机交叉临床验证显示，该系统使45%决策的真实诊断排位得到提升，增强了62%情况下医生的诊断信心，并将诊断耗时缩短了21%。
方法与数据
- 依托统计元聚合（statistical meta-aggregation）与知识增强智能体反思实现多范式融合；评估基于2,528例严格隔离的临床病例。
价值判断
- 值得关注：成功弥合了算法测试基准与临床可操作可靠性之间的差距，大幅改善罕见病漫长的诊断困境。
- 可复用点：多正交AI范式协同聚合与智能体反思架构，可复用于其他高风险、复杂医疗诊断场景。
- 局限/待核查：系统的计算资源开销以及在更多未见罕见病种上的泛化表现，摘要未明确提及。
