Mercury 2, the new diffusion language model from Inception labs scored 43.2% on WeirdML (my benchmark). For reference this is comparable to o1 or opus-4. It is at the cost/accuracy frontier (and of course much much faster than comparable models), although still far behind the top models (gpt-5.3 at 79.3%).
I had expected this model to do much worse (as most models you hear about from non-frontier labs), but this is a very solid result.
