Chubby♨️@kimmonismus · XAnthropic的Claude 5 Fable（代号Mythos）在几乎所有AI能力基准测试中达到SOTA，长复杂任务优势尤为显著。模型更节约token，可在数百万tokens长任务中保持专注。Stripe早期测试中，Fable 5将5000万行Ruby代码库的迁移压缩到一天完成，而人工团队需两个多月。Gemini 3.5 Pro与GPT-5.6临近发布（GPT-5.6最早下周推出），面临压力。此次发布提振了Anthropic即将进行的IPO，证明其在性能与效率上仍能大幅跃升。
It's already June 9th， and Gemini 3.5 Pro and GPT-5.6 are nearing release （Google even already announced 3.5 Pro during i/o）
Rumor has it that GPT-5.6 will be released as early as next week.
So far， it's safe to say that - guardrails aside - Anthropic is truly the frontier lab that's entering a new league with Mythos/Fable.
Gemini 3.5 Pro and GPT-5.6 have a lot to deliver and are now under pressure.
This release has certainly boosted Anthropic's upcoming IPO. Anthropic has proven that they are still capable of making significant leaps in performance and efficiency. There's no end in sight.
But the pressure on the competition is mounting.
And remember that Claude Mythos was （and probably is） still leader in Long Horizon software Tasks
