The question is: what proportion of tasks can not be handled by GLM5.2?

How many software developers were working on code like the one you describe?

On that aspect, I agree. Smaller / open models are becoming "good enough" at an increasing number of tasks. And that's great for us, consumers. But there will always be tasks that are "worth" pursuing with better models, and cost is irrelevant for those tasks. That was the point I was trying to make.
