Nejumi 4 - GLP - Syntactic Analysis: leaderboard

Grammaticality tasks from the jaster harness. On the JCoLA in-domain and out-of-domain splits the model labels a single Japanese sentence as grammatical or not, and on JBLiMP it picks the grammatical sentence from a pair. Each dataset is the mean of its 0-shot and 2-shot runs graded by exact match, and the board averages them in percent where higher is better. Source: github.com/wandb/llm-leaderboard.
