Anthropic explains Claude Code’s recent performance decline after weeks of user backlash

Anthropic, the AI lab valued at $380 billion, has acknowledged that a series of engineering missteps were behind a widely experienced decline in the performance of its Claude Code tool that sparked a user revolt over the past month.

The latest admission, which came after weeks in which Anthropic had initially implied in its communications that nothing was wrong and that users were largely to blame for any performance problems and later said some of the changes had been made for users’ benefit, has done little to calm Anthropic’s customers—some of whom say they have already canceled their subscriptions.

The feeling among some users that Anthropic had been gaslighting them potentially undercuts Anthropic’s attempts to market itself as more transparent and aligned with its users than rival OpenAI. Nor has the admission that there were performance problems done much to quell rampant speculation that the company is running short of computing resources and that Anthropic’s efforts to ration precious computing power were the real reason for the performance issues.

“Demand for Claude has grown at an unprecedented rate, and our infrastructure has been stretched to meet it, particularly at peak hours,” Anthropic said in a statement to Fortune. “We are doing everything we can to address this, and we are deeply grateful for our users’ patience.”

The statement went on to say that “compute is a constraint across the entire industry, and we are scaling our compute rapidly and responsibly—including through a recently announced expansion of our partnership with Amazon and Google, which will bring significant new capacity online in the coming months. Our priority is getting that capacity into our users’ hands as quickly as possible.”

The company also pushed back on any characterization that it had not been transparent with its users about the issues impacting Claude Code. “The Claude Code issues had specific technical causes that we documented in full in our postmortem, and the fixes are now shipped,” the statement said.
