17 GoLang microservices for a serious project were written perfectly using the latest version of QWEN(3.6). The only areas where we really had to work hard were documentation and a very serious task breakdown. All of this was tested, and yes, a review was required, but everything was within reason. The deadline was 10 days of 24/7 work, including the review. When attempting to submit the same task, Opus 4.7/4.6 had to be stopped after three hours. If you have significant resources for experimentation, you can certainly try. For us, the choice is absolutely clear at this point.
