I think for myself, it's close to 25% if I only take my role as a dev. If I take my 'senior' role it's less, because I spend way more time in reviews or in prod incident meetings.
Three months ago, with opus4.5, I would have said that the productivity improvement was ~10% for my whole team.
I now have to contradict myself: juniors and even experienced new hires with little domain knowledge don't improve as fast as they used to. I still have to write new tasks/issue like I would have for someone we just hired, after 8 months. I still catch the same issues we caught in reviews three months ago.
Basically, experience doesn't improve productivity as fast as it used to. On easy stuff it doesn't matter (like frontend changes, the productivity gains are extremely high, probably 10x), and on specific subjects like red teaming where a quantity of small tools is better than an integrated solution I think it can be better than that.
But I'm in a netsec tooling team, we do hard automation work to solve hard engineering issues, and that is starting to be a problem if juniors don't level up fast.
