Anthropic makes some of the most popular coding models out there, and it seems to be using them heavily itself.
Anthropic CEO Dario Amodei says that “a majority” of the code at Anthropic is now being written by AI. “If you look at coding — coding is one area where Anthropic models have advanced very quickly, adoption has been very quick,” he said in an interview. “We released Sonnet 3.5, Sonnet 3.6, Sonnet 3.7, Sonnet 4.0 and Sonnet 4.0 Opus. In that series of 4-5 models, each one got substantially better at coding than the last,” he added.

“The real usage has grown exponentially. We’re heading towards more and more these models being used autonomously. I think the actual majority of code that’s written at Anthropic at this point is written by, or at least with the involvement of one of the Claude models. Various other companies have said similar statements to that. We see the progress as being very fast — the exponential is continuing, and we don’t see any diminishing returns,” he added.
Other companies have indeed talked about how much their using AI to write code. Google had said in April this year that “well over 30 percent” of the code at the company was being written with AI. Microsoft had ascribed a similar number. Salesforce, meanwhile, has said that it won’t hire any human engineers this year because of the efficiency gains it’s seeing from AI. Inmobi has said that 80 percent of the code at the company will be generated by AI by the end of the year.
However this automation doesn’t seem to currently leave the human engineer out of the loop entirely. While Microsoft has laid off some employees in recent times, the layoffs haven’t been close to the numbers that this level of automation would suggest. Anthropic itself is aggressively hiring engineers, with plenty of job openings on its website. NVIDIA CEO Jensen Huang says that AI is freeing up time of engineers from working on mundane tasks to building even more products and services, and there’s plenty of things for engineers to work on. It remains to be seen how long these trends hold for, but even as automation numbers cited by industries leaders keep rising, there currently seems to be no massive job cuts at these companies as these numbers would suggest.
