r12 - a 27k prompts, 12 task domain 3rd iteration of the ReasonScape evaluation. Compared to the previous m12x ranking this evaluation fixes a slew of test bugs, refines the task set to add table-extraction, and lifts the context ceiling to 16k - so these rankings are quite a bit different vs the previous m12x Leaderboard (which has an 8k context limit).
