48 小时内 AI 价格战：Grok、Opus 5.5、GPT-6 Sol/Luna 连环降价
梳理 xAI 先降价、Anthropic 与 OpenAI 相继跟进，Sol 定价 $2/$10、Luna 低至每百万 10 美分，作者认为智能竞赛停滞、只剩价格战。
The AI price war just kicked off and it all unfolded in the span of 48 hours It started with xAI dropping Grok 4.7 at $2 per MILLION tokens, undercutting the entire frontier by 80% The next day Anthropic dropped Claude Opus 5.5, then OpenAI answered within hours, launching GPT-6 Sol and Luna at half the price of the last generation and making the cut permanent Sol now runs at $2 in and $10 out, undercutting Anthropic's new model by half Luna dropped to 10 cents per MILLION tokens, cheaper than almost every serious AI model in existence None of these models are much smarter than the last, the intelligence race stalled, so now it's a race to the cheapest When AI's biggest players compete on price instead of power, it means the breakthroughs have slowed
