Here is the top 10 right now:

I also checked how the Claude models did specifically:

No other Anthropic model seems to be there for now. I would have been very curious to see the more recent ones.

I needed this. I had no idea it existed.

I have bent over backwards trying to enforce brevity with deepseek v4 flash to the point where I think I broke some things trying to do prompt injection in my Hermes setup and was still unsuccessful.

Meanwhile Sol blows me away and I want that to be my default for everything now.

In general though I seem to have the most success with a "<=10w" requirement in my prompts.

What I don't see listed and would be a good comparison is the STS models. OpenAI's live model is an absolute joy to talk with.

This defies Betteridge's law of headlines.

Yes, yes they do
