CURRENT BOARD · v1.1
AI alphabet leaderboard.
All 42 published models, ranked by blind Bantu mean. A high ranking does not mean an alphabet has been mastered.
ABC Test. The ABC Test is simple: complete means complete. Missing even one required unit—or inventing one that does not belong—means FAIL. Only a fully correct operating alphabet earns PASS. A model can rank #1 and still FAIL: the score out of 26 measures relative performance; PASS / FAIL is the strict completeness verdict.

42 model records · No score is converted into an invented zero.
Scores are normalized to 26, not counts of literal alphabet units. A displayed 26.0 requires underlying exact recall and precision verification before any PASS claim. The published board and exported evidence have different coverage.
