The State of AI 2025 survey polled thousands of developers to understand how AI tools fit into real workflows. The survey found that some AI coding tools are gaining mainstream adoption, but there are still barriers to their use. Cursor is winning among developers for fast prototyping and refining output with manual reviews, while v0 is the most widely used codegen tool with high positive sentiment. Model providers like Open AI's ChatGPT and Copilot remain dominant in the market, capturing 91.2% of total awareness for ChatGPT. The survey highlights both the benefits and challenges of using AI tools in development workflows, including issues with code quality and editor lock-in.
