While on the surface this might look like an absolutely atomic performance degradation, it's actually nothing. Rendering each time can vary give or take two seconds, despite the ray tracer being fully deterministic. I usually chalk this up to "gremlins in the computer" and by that, I mean things like the OS doing context switching and CPUs having dynamic clocks. The best thing to do would be to take 250 runs of this. I don't think it's worth it. From a heuristic standpoint 0.1 seconds is not a lot of time out of 102. Also clang on the M4 doesn't have that much of a speedup when doing asin_cg_estrin() vs the plain asin_cg().
更现实的问题是，真正好用的 AI 产品往往还需要服务器、算力、存储和稳定的默认配置，开源社区很难长期承担这些成本。龙虾本身就已经暴露了这一点：它不够易用，不配置 token 基本无法直接使用。未来大厂推出的“闭源龙虾”，大概率都会是开箱即用的。。业内人士推荐手游作为进阶阅读
Zeno, an African startup, raised $25 million in a Series A round to expand its app-controlled battery-swap network and produce more of its Emara motorcycles. About $20.5 million of that was an equity fundraise led by Congruent Ventures with participation from Active Impact and Lowercarbon Capital. The remaining $4.5 million is a debt facility from Camber Road and Trifecta Capital.，推荐阅读超级权重获取更多信息
