scaling01 shared a screenshot of the Epoch Capabilities Index (ECI) leaderboard joking "I swear I didn't touch Fable's ECI lmao". The top entries shown — Claude Fable 5.2 (ECI 173, 90% CI 170–177), Gemini 4 Carbon (170), GPT-6 Astra (169), Claude Opus 5.5 (169) — are not real released models, making this look like demo/placeholder data or an in-joke. Fun AI-circle moment worth sharing as a curiosity.
