Anthropic has found itself under the radar either<\/a>. The company has previously been accused of trying to remove Claude Code access from its $20 Pro plan.<\/p>\nAnthropic fixes bug that made Claude dumber<\/p>\n
The Dario Amodei-led startup shared an update on addressing these complaints. Anthropic stated, \u201cWe never intentionally degrade our models.\u201d The company said that it fixed three separate issues in a patch released on April 20 that may have resulted in complaints from users. Anthropic has also reset all user limits, which gives you more access to Claude Code to work with.<\/p>\n
Anthropic stated that the issues affected Claude Code, the Claude Agent SDK, and Claude Cowork, while its API and inference layer were not impacted.<\/p>\n
Boris Cherny, the head of Claude Code, claimed that the company needed an intensive investigation to find the root causes. He wrote on X, \u201cWe take these reports incredibly seriously. In my time on the team, this has probably been the most complex investigation we\u2019ve had.\u201d<\/p>\n
What was the issue?<\/p>\n
According to Anthropic, three changes to Claude resulted in users feeling that Claude had just become dumber. The company stated that on March 4, it changed the default reasoning setting for Claude Code from \u201chigh\u201d to \u201cmedium.\u201d This was meant to reduce the time for a response from the AI, but this was not what users wanted. Anthropic added that users said, \u201cthey’d prefer to default to higher intelligence and opt into lower effort for simple tasks.\u201d<\/p>\n
The second problem came on March 26, from a change in Claude that would delete the AI\u2019s older thinking from sessions that had been idle for over an hour. That is, the AI would forget old sessions till you actually resumed it. Here, Anthropic says, \u201ca bug caused this to keep happening every turn for the rest of the session instead of just once, which made Claude seem forgetful and repetitive.\u201d<\/p>\n
On April 16, the third issue arose with change in how Claude responds. Anthropic reduced the \u201cverbosity\u201d of the AI, that is how wordy the AI is while responding. But the company says that this “in combination with other prompt changes, it hurt coding quality\u201d<\/p>\n
Anthropic said the combined effect appeared as broad and inconsistent degradation because each change affected a different slice of traffic on a different schedule. Ultimately, the company claims it has fixed all three issues, and now users will not have trouble with how Claude Code performs.<\/p>\n
