Anthropic Quietly Starves Fable 5

🔥 What happened A developer spent six weeks sniffing wire logs from Anthropic's Fable 5 and found the model itself unchanged — but the inference regime behind it quietly gutted. Despite xhigh/max settings, the model now thinks far less and in more fragmented bursts than at launch. 💡 Why it matters 43,261 invocations across 65 days show thinking-token volume steadily declining and fluctuating wildly. Reproducing frontier capabilities isn't about model access anymore — it's about inference regime access. That can make results an order of magnitude more expensive than headline rates suggest. ⚡ Our take "Nerfing" isn't a meme anymore — it's measurable. Anyone trusting benchmarks without auditing the inference pipeline is flying blind.
