No one serious is using the open models. Using them is like traveling back 2-2.5 years in time and using ChatGPT.

DeepSeekv4 Pro is roughly Opus 4.5 - Opus 4.6 in my estimation. That's about 8 months difference, not 2.5 years.

It's definitely not as good. But it's also definitely good enough.

		Curious- in what tasks? I find Opus 4.5/4.6 too expensive and have tried to migrate to DeepSeek for C++ work, but found it couldn't cut it. What's your DSv4 setup? What harness? It sounds like I should give it another try!
