I find that Deepseek Pro to be below Sonnet 4.6 for much of the coding/review/executing tasks from plan. The only good thing it has going is the price. It will is cheaper for it to crunch through your well worked out implementation plans, it's slower, makes more errors, needs more tokens to fix those. And even at that increased spent it does deliver in the end. More tokens, lower cost, slower.
I use it as something that sits right below Sonnet for daily tasks that can be run in loops with validation checks, perfect. Anything more advanced...it just doesn't cut it.
Same experience with z-ai glm 5.1 btw... don't know what system prompt magic antrophic set in front of their Sonnet 4.6, but it does execute tasks efficiently.
claiming any of these deepseek models are close to opus is a bit optimistic
I tried DeepSeek and MiMo through both Claude Code and Pi.dev. I found Claude Code a slightly better harness, but I still have both installed and switch around frequently.
As for "open source AI", what exactly are you talking about? Is it open models?
I tried some through Ollama, but I don't have the hardware to run decent models.
