Artificial Analysis details GPT-6 Astra's pricing and benchmarks: $10/$50 per million input/output tokens, 2.5x GPT-5.6 Sol's $4/$20, with the same 90% cache-read discount and 25% cache-write premium. Two stories emerge: Astra matches Fable 5 on the Coding Agent Index at less than half the cost thanks to big token-efficiency gains, while on the Intelligence Index it uses fewer tokens than GPT-5.6 Sol for similar performance — but the higher price outweighs the savings.
