I've been switching across all different models this week with OpenCode and Pi - we're in an interesting place now because the open models are definitely "good enough" for a wide range of coding tasks and MUCH cheaper. They certainly aren't AS good, especially once you get into unfamiliar territory - custom enterprise frameworks etc where model knowledge falls off and general intelligence kicks in. But then, with time people will build up custom skills and agent files for those. And the open models will also get better.

I could easily see us in a place 2 years from now where this coding application is fully commoditised.
