摘要

推特消息称，有人通过第一性原理推导出GPT-5预训练的token数量、Gemini 3的KV缓存字节数以及Claude缓存命中的内存类型。

客观事实
  • 推导了GPT-5预训练的token数量
  • 推导了Gemini 3的KV缓存字节数
  • 推导了Claude缓存命中的内存类型
GPT-5 Gemini 3 Claude

原文

Btw a bunch of the questions were just off the cuff - nothing @reinerpope prepped for.

The guy is just first principles deriving how many tokens GPT 5 was pretrained on, or the bytes per token in Gemini 3's KV cache, or which kind of memory each Claude cache hit sits on.
