I'll choose not to respond to your personal attack.

But in term of actually running a dev team - you are free to use QWEN or another quantized local model that can run on an RTX 5090 for coding if it makes you feel more independence. However you would struggle and spend many many more hours achieving the same thing, with a lot more debugging time, long delays before it's done, and many more prompts.

It's just not the right approach. I use QWEN and other local models all the time, but for more clearly defined monitoring and classification tasks.
