MiniMax M3 ranks 7th on Long-Horizon Terminal-Bench, open-weight version leads

MiniMax AI's M3 model has achieved the seventh position on the Long-Horizon Terminal-Bench, a benchmark designed to evaluate model performance on extended tasks. Additionally, an open-weight version of the model secured the top spot among open-weight models tested on the same benchmark. The Long-Horizon Terminal-Bench, established around May, previously indicated that even the top-performing models could only complete seven out of 46 tasks, with an average completion rate of two tasks across all tested models.
