Anthropic released Claude Fable 5.2 on November 9, reporting higher scores than OpenAI's GPT-6 Astra on two coding benchmarks. However, the lower list price of Fable 5.2 doesn't equate to a lower bill. The cost structure is based on tokens, the chunks of text a model processes. Fable 5.2 costs $8 per million uncached input tokens and $40 per million output tokens, while Astra charges $10 and $50 respectively.
In the report's tests, Fable 5.2 used significantly more tokens than Astra, costing $2.51 compared to Astra's $0.98 for bug fixing. Despite the higher cost, Fable 5.2 scored 50 on code writing and 49 on code review, while Astra scored 45 on code review. Astra proved to be the more cost-effective option for these tasks, matching Fable 5.2's scores at about 41% of the estimated cost and finishing all tasks faster.
