Looks like it's DeepSeek v4.1 Flash day, not just for VulcanBench, but also for Artificial Analysis! Safe to say the Cyber Index is becoming a more and more important index by the day at this point. I found that DeepSeek v4.1 Flash is very proficient at coding when testing on VulcanBench Frontier v4, and now, seeing these results, looks like it also has some serious Cybersecurity superpowers too!
