> I couldn’t even imagine having to go back to a model from 12 months ago, much less 24 months ago. GPT-5.5 is so much better than GPT-4o that it sure seems like they keep finding new juice to squeeze The difference in progress in smaller models is far more impressive. Compare Gemini 3.5 Flash to a ~16B parameter model from 24 months ago. Compare GPT-5.5 to a frontier model 24 months ago. Yes, GPT-5.5 got better. At orders of magnitude smaller parameter sizes (when factoring in ACTIVE parameters) the increase is far more pronounced.
