Using up to 32k thinking tokens, Sonnet 3.7 set SOTA with a 64.9% score.

  65% Sonnet 3.7, 32k thinking
  64% R1+Sonnet 3.5
  62% o1 high
  60% Sonnet 3.7, no thinking
  60% o3-mini high
  57% R1
  52% Sonnet 3.5

Also for $36.83 compared to o1's $186.50

But also for $36.83 compared to DeepSeek R1 + claude-3-5 it's $13.29 and for latter "Percent using correct edit format" is 100% vs 97.8% for 3.7.

edit: would be interesting to see how combo DeepSeek R1 + claude-3-7 performs.

is there any public info on why such DeepSeek R1 + claude-3-5 combo worked better than using a single model?

My personal experience is that R1 is smarter than 3.5 sonnet, but 3.5 sonnet is a better coder. Thus it may be better to let R1 to tackle the problem, but let 3.5 sonnet to implement the solution.
