OpenAI's GPT-6 Sol and Luna cut prices in half but barely move the needle on performance

OpenAI's new GPT-6 Sol and Luna models cost half as much as their predecessors while maintaining similar performance levels, competing directly with Anthropic's pricing. Independent analysis shows minimal improvements in raw intelligence compared to prior versions.
Why it matters
The price war between OpenAI and Anthropic makes advanced AI models more affordable, but performance plateaus suggest the models are reaching diminishing returns.
