GPT-5.6 sol is half the price and ~twice as token efficient as fable in many cases for accomplishing the same task.
happy to deliver at one-quarter of the price.
OpenAI CEO Sam Altman's quarter-cost claim for GPT-5.6 Sol combines two asserted advantages. In his July 14 post, he said Sol was half the price and roughly twice as tokenThe chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.Full definition →-efficient as Anthropic's Fable in many comparable tasks.
The arithmetic is conditional: half the unit price multiplied by half the usage produces one-quarter of the cost. That explains why comparing token prices alone can miss a task's total bill. The post does not identify its task sample or provide results establishing that ratio across workloads.
