Claude Fable 5.2 is meant to be the smartest AI model in the world. So I put it head to head with Opus 5.5 to build 100 Bitcoin trading strategies each. In the video, I test all 200 on a full year of data neither model ever saw, break down the two numbers that matter when you read a backtest, then take a strategy from TradingView to a live bot on Bybit, which is where it gets real.
