Fable 5とGPT-5.5 pro の知能の差がよくわかる質問がこれ。AI時代に人間がやるべき事は理解することであって計算することや計算のやり方を考えることではない。計算はAIの仕事だが、理解をAIに外注することはできない。 左：Fable 5、右：GPT-5.5 pro

Fable 5との3日間の思い出 ・失ったもの：4万円と時間 ・得たもの：束の間の未来へのタイムスリップと常時稼働Macへのシステム的遺産、200万インプレッション、700フォロワー ・４万円は返金の可能性あるし、Xからお小遣い貰えるから経済的にはプラスかな？ ・まあ、そんな小さいことより何物にも代えがたい体験な貴重だった ・未来が見えたことでいま何を準備しておけばいいか理解できた ・かわぐちかいじの「ジパング」のように未来を知っていればどう行動すれば良いかがわかる ・Anthropicへの期待は爆上がり ・Fableの遺産を活用するため当面Claude Codeと Codex半々の運用にする ・これって「ドラえもんは全部夢でした」みたいな夢オチじゃないよね？ ・I miss you, Fable 5.

Fable 5を2日間使った感想 ・IQは最強でGPT-5.5 pro の比ではない ・EQは高いのにKYで、真実を追求する ・ビジネスなど人間世界の理解が半端ない ・現実世界に適用できる提案力も半端ない ・なのに回答スピードは比較的速い ・主力LLMの座はGPT-5.5 proから交代 ・そのためにMaxプランにアップグレード済 ・常時稼働なしならMax5倍でトークン量は十分 ・Codex派だったがClaude Codeに乗り換え済 ・GPT-5.6 proでも超えられない可能性が高い ・結論：このモデル、ヤバすぎ。非エンジニアもみんな使うべき

I’ve had a number of conversations with folks inside and outside government about the current situation with Anthropic, and here is what I believe to be true: — As we know, Anthropic publicly released its Mythos class models earlier this week under the commercial name Fable. — Fable is Mythos with guardrails. But if those guardrails fail, then you’ve exposed Mythos and its advanced cyber capabilities to people who shouldn’t have them. (Keep in mind that Anthropic itself widely promoted the idea that Mythos was a cyberweapon and needed to be regulated as such. They asked for government regulation of Mythos and championed the guardrails on Fable. If there is a vulnerability — big or small — it is Anthropic’s responsibility to patch.) — A highly credible trusted partner of both Anthropic and the USG who was testing Fable came forward with a jailbreak of those guardrails. The Admin asked Dario to fix the jailbreak or de-deploy the model. Dario refused. — In their blog post, Anthropic defended its decision by saying the jailbreak isn’t serious. That is not what the trusted partner and the USG believe; nor is that kind of minimizing language consistent with Anthropic’s brand as the AI safety company. It’s difficult to fathom how they could claim a jailbreak allowing operability of a cyber weapon could be defined as not “serious.” — In the past, Anthropic has always said that safety must be top priority and taken super seriously. In this case, Anthropic prioritized the continued offering of the consumer model over safety. — In reaction, the Admin issued the export control. The Admin did this reluctantly. It’s been very surprised that Anthropic hasn’t wanted to cooperate with a reasonable safety request (ie fixing the jailbreak issue). Anthropic’s reaction is very much at odds with their branding and ethos as a safe AI research community. — The Admin’s hope now is that Anthropic remediates the safety issue, the export control is lifted, and Fable goes back into general release. The Admin wants all of this to happen as soon as possible. It is frankly bewildered that Anthropic hasn’t wanted to comply with safety requests that it previously said were its highest priority. — Those trying to misdirect and tie this action to the prior DoW/Anthropic issues are wrong. The Admin values Anthropic’s technical capabilities and feels that this issue, while serious, should be easily resolved. The ball is in Anthropic’s court.
