Karim Mattar(@MattarARK):A week ago OpenAI owned 11 of 15 seats on this frontier. Yesterday Opus 5.5 kicked Astra off the top and Anthropic owns more of the peak again, while Sol and Luna flood the cheap end at half the old price. This market resets every few days now. The labs that win are the ones who can live there.

How quickly things can change! Here's the updated frontier with Opus 5.5, GPT-6 Sol & Luna incorporated. Opus 5.5 has kicked Astra off the frontier, giving Anthropic more ownership of peak intelligence than before, while OpenAI still dominates the mid to low end of the frontier with GPT-6 Sol & Luna coming in smarter and 50% cheaper than their prior 5.6 generations. Xiaomi's MiMo takes the rotating open source spot for today, but otherwise the entire AA Pareto frontier is dominated by just Anthropic & OpenAI.
