传闻 Claude Fable 5.2 泄露，被指跑赢 GPT-6 Astra
有测试者称 Anthropic 悄悄把部分请求路由到未公布的 Fable 5.2，同题对比中胜过 Astra，但更慢更贵，且无官方模型卡佐证。
🚨 FABLE 5.2 OUTPUT IS LEAKING AND PEOPLE ARE SAYING IT COOKS GPT-6 ASTRA This render is what's circulating, a fully interactive product page for a fictional VR headset called Orbit, exploded component views, live camera modules, glowing internal parts, built entirely from a prompt. The claim going around: Anthropic quietly started routing some Fable 5.1 requests to a new checkpoint inside Claude Code, Chat and Cowork. Testers noticed the swap and started comparing outputs directly against Astra on identical prompts. The most cited result, from tester @notjazii, running high reasoning mode: Fable 5.2 output described as a clear leap over 5.1, and beating Astra on the same task. Tradeoff noted: slower and more expensive to run. Here's the part worth being honest about before this gets repeated as fact. As of right now there's no model card, no API identifier, no listing on Bedrock, Vertex, or OpenRouter, and no statement from Anthropic. Every version of this story traces back to a small number of accounts, not a confirmed source. That doesn't mean it's fake. Anthropic has quietly routed traffic to unannounced checkpoints before. It just means "leaked" here currently means "routing behavior a few testers noticed," not "official release." Watch for an actual model identifier showing up in the API before treating this as confirmed.
