前沿模型同分扎堆：GPT-6 Astra、Opus 5.5、Gemini 4 都是 53
作者指出三家旗舰模型在智能指数上同分 53，说明前沿能力正在趋同，API 价格战会把推理利润压到零。
Gemini 4 Argon hitting 53 on the Artificial Analysis Intelligence Index at one-third the cost of Claude Opus 5.5 sounds like a major pricing breakthrough until you check the rest of the chart. Opus 5.5 holds the high mark, but right behind it sits an unbroken knot: • Claude Fable 5.1: 53 • GPT-6 Astra: 53 • Gemini 4 Argon: 53 Comparing Gemini 4 Argon against Opus 5.5 makes Google look aggressive on inference pricing. But set against GPT-6.1 Sol, Argon is still more than twice the price for similar performance. When frontier models cluster at the exact same benchmark score, the illusion of a technical moat evaporates. Measuring affordability against the priciest outlier on the board hides what is actually playing out: frontier intelligence is standardizing, and API margins are getting competed straight down to zero.
