  "text": "Use Case 3: One-Shot Blindfold Chess\n\nCan an AI hold an entire game state in memory without drifting?\n\nTo test Fugu Ultra’s persona stability and sustained memory, we had it play 4 back-to-back games of blindfold chess. Every model played the same way: no board shown, requiring them to hold the full game state entirely in memory.\n\nWe matched Fugu Ultra against 3 leading frontier models and a 2100-Elo Stockfish engine.\n\nThe Results: Fugu Ultra outplayed all 4 opponents. Where the other models eventually drifted or lost track of the board state, Fugu remained accurate, ending every single game in checkmate.\n\nWatch the full sequence below to see Fugu capitalize the moment the other models slip.",
