All shared logs reviewed
Boris Cherny, who leads the AI programming tool "Claude Code" at Anthropic, reported on X on Oct. 28 (Oct. 29 Japan time) the results of an investigation into complaints that usage limits were being used up faster than expected.
According to Cherny, the team reviewed all the session logs shared by users. As a result, it found several small bugs that sped up token consumption and is rolling out fixes in stages. However, no single root cause was found, he said.
He did not say which bugs increased consumption or by how much, or whether lost usage would be compensated.
Complaints over usage limits continue
Regarding Claude Code usage limits, there was also a wave of reports in March that short prompts were using up large portions of the limit, and Anthropic acknowledged it was investigating. The person in charge at the time cited possible bugs related to the caching mechanism that reuses conversations and to resuming sessions.
In October, an analysis also suggested that the company was testing different limit sizes with some users. On Oct. 30, two days after the report, Anthropic renamed its $200-a-month plan "Ultra" and removed the five-hour limit.
