A study by METR reveals that software developers overestimate the productivity gains from AI, as they took 19% longer to complete tasks when using AI tools, despite anticipating a 24% time savings. The findings suggest that while AI may not hinder productivity, developers' trust in AI models and the complexity of mature codebases can lead to misconceptions about efficiency.

Cognition has launched a new low-cost plan for its AI programming tool Devin, reducing the entry price to $20, with a pay-as-you-go option. Despite initial praise and claims of improved performance in Devin 2.0, the tool still struggles with complex tasks and has faced criticism for introducing bugs and security issues in its code output.
