For people cranking out SaaS / web services / web pages / "full stack" work I don't see a huge difference.

If you're building an optimizing compiler, a CUDA kernel, a database, a high performance concurrent data structure with tricky locking, etc. etc. it's still not really close. Sol 5.6 on high just slays e.g. GLM 5.2 for this kind of work for me.

I'm sure K3 is fine for these things too, but I can't afford it at its API rates compared to a Codex coding plan.

For now.
