This chart captures Claude’s improved coding capabilities. Before 23 May, syntax error rates fluctuated between 0.15% and 0.25% across different programming languages and application scenarios generated on the Loveable AI app creation platform. After the Claude 4 rollout error rates dropped and have remained consistently low. Feedback on the new Claude has ranged from disappointment to excitement, but if it’s code you’re interested in generation 4 is a step up.
