> Deepseek 4 Pro

There's your problem, 4.1 Flash is significantly better and cheaper, to the point where the official DeepSeek API is going to (or already has, I forget) redirect requests for Pro to 4.1 Flash, and adjust billing accordingly too.

4 Pro is still offered by providers I'm sure, since it's open weight, so I can understand making that mistake.

That's an unfortunate experience. Think of v4.1 flash as actually v5.0 flash. It's night and day compared to the 4.0 flash (and 4.0 flash was unintuitively better than 4.0 pro). I would re-evaluate with v4.1 flash. I'm not saying it better than Sol or anything, but it's in the ballpark.

You mean 4.1 Flash which is the first great Deepseek? The one that actually surpasses Opus in my books now.
