Two month ago, i'd say 5%. With Opus4.5, Gemini 3 and gpt 5.2, it's now 20%, maybe 50% if we only talk about personal code output. If we talk about my whole team output, I'd say the impact on code production is like 80-100%, but the impact in velocity is between 10% and -25%. So many bug in production, security holes, so many poor models definition making it to production DB only for me and the other true senior to have to fix it. We are seniors, we read your PRs and try our best to do it thoroughly, but with AI multiplying your code output, and writing quite convincing solutions, it's way harder, so please: if an AI have written the code in your PR, verify the tests are not superficial, verify everything works, think for yourself about what the model is used for and if it can be improved before release. Re-verify the tests (especially if the AI had issues writing/passing them). And do it once more. Please (hopefully one of my coworkers will read this).
