Timeline (last 90 days)
Oct 19
Bug 3 was confirmed on Haiku 3.5 and rolled back on September 4; Anthropic believes it may have affected some Sonnet 4 and Opus 3 requests on the Claude API, and Opus 3 was rolled back on September 12; the final fix was to switch to exact top-k and normalize some operations to fp32, accepting a slight efficiency loss.
