GPT-6 Astra uses about one-third the tokens of GPT-5.6 Sol at maximum reasoning, lowering cost per task below Fable 5. On the Intelligence Index, it scores 61 points, matching GPT-5.6 Sol and Muse Spark 1.3, with cost efficiency hurt by higher API pricing.","whyItMatters":"GPT-6 Astra's strong token efficiency places it on the Pareto frontier for coding cost versus score, even as higher API prices weaken its standing on the Intelligence Index.","webCardHtml":"\u003cp\u003eArtificial Analysis published GPT-6 Astra results on September 3, 2026, covering both the Coding Agent Index and the Intelligence Index. The coding score of 67 points ties Fable 5 and comes close to Claude Opus 5 at 68 points, while Fable 5.1 leads with 70 points.\u003c/p\u003e\u003cp\u003eToken efficiency is the main differentiator. At maximum reasoning on Codex, GPT-6 Astra consumes roughly one-third the tokens of GPT-5.6 Sol and about one-seventh of Claude Opus 5. That efficiency cuts cost per task to less than half of Fable 5\u0026#39;s, despite both scoring 67 points. GPT-6 Astra therefore sits on the Pareto frontier, meaning it offers the highest score for its cost or the lowest cost for its score among tested models.\u003c/p\u003e\u003cp\u003eThe Intelligence Index tells a different story. GPT-6 Astra\u0026#39;s 61 points tie GPT-5.6 Sol and Muse Spark 1.3, five points behind Fable 5.1. Its API pricing of $10 per million input tokens and $50 per million output tokens is 2.5 times GPT-5.6 Sol\u0026#39;s, raising cost per task by 75 percent.\u003c/p\u003e","blueskyPost":"GPT-6 Astra matches Fable 5 on the coding index while using a third of the tokens, but its higher API price cuts the cost advantage. Fable 5.1's 70-point lead remains the gap OpenAI priced itself into.","twitterPost":"GPT-6 Astra's token efficiency undercuts Fable 5's cost model, yet its own pricing erases that edge against Fable 5.1.","threadsPost":"GPT-6 Astra ties Fable 5 on coding while using a third of the tokens, a clear efficiency win.
