Claude Fable 5 / Mythos 5 全面胜出。 我以为 Fable 5 只是弱化版 Mythos Preview,但它实际更强。SWE-Bench Pro:Fable 5:80.3%,GPT-5.5:58.6%。 而且价格仅为 Opus 4.8 的 2 倍:$10/输入 MTok,$50/输出 MTok。 我认为 GPT 5.6 无法超越这个成绩。
Claude Fable 5 / Mythos 5 wins everywhere.
I thought Fable 5 was just a nerfed Mythos Preview, but it's literally better. SWE-Bench Pro: Fable 5: 80.3%, GPT-5.5: 58.6%.
And the price is only 2x Opus 4.8: $10/input MTok, $50/output MTok.
I don't think GPT 5.6 can beat this…
