It is also a big deal because it is just plain good. And it is a big deal because even with all of this, the frontier of AI ability remains jagged.
It is increasingly hard to quickly demonstrate each generational change as AI has gotten better, since a lot of the old things AI was bad at, like math or counting letters in words, are now trivial for AI to do. So, I will give you the complicated details, but first, a simple example that I think is a good illustration. What AI models are best at is coding, so I gave a coding challenge to AIs ranging from OpenAI’s first reasoning model, o3 (released a year and a week ago!) to the current best open weights model (Kimi K2.6) to the new GPT-5.5 Pro…
