…Are they just running V4 in parallel for streamed CoT, on the off-chance someone tries to distill it? Or maybe even V3.2. This is a completely generic Chinese open weights CoT style. Would be a devilish scheme
LEAKED: Another leak of what *appears* to be the internal CoT reasoning trace of Fable 5 by @AnthropicAI has surfaced! This is highly interesting because the reasoning traces are closely guarded secrets of any AI company.
Compared to earlier leaks, this trace looks comparatively close to normal English, and not so abstract and alien. You can see Claude going back and forth on ideas and talking to itself. Each trace ends with a closing </thinking> tag, a strong indication that this is legit.
h/t @Lucknite for the information!
