GLM-5.3 vs MiniMax M3

GLM-5.3 wins this one, and the intervals say it's real: its Elo floor of 1989.0 sits well above MiniMax M3's ceiling of 1813.1. On the board that's #24 at 2041.5 Elo against #42 at 1781.0, a 260.5-point gap, and 86.83 to 83.44 overall. The records make it concrete: GLM took 866 wins with just 8 losses, while MiniMax lost 294 times. The quality gap is widest exactly where scripts go wrong. The numbers-and-slop metric is 86.75 to 78.11, slop is 91.64 to 86.04, and GLM also takes tone and voice, 87.89 vs 83.34, and continuity and emotion, 85.11 vs 80.48. MiniMax gets two things back: length adherence, 89.72 to GLM's 87.5, and an essential tie on visual cues, 81.21 to 81.43. Then the bill. Both are open weights, but MiniMax costs about two cents per script against GLM's eleven, nearly 5x cheaper, and it turns scripts around far faster, 109.94 seconds on average against GLM's 301.95. That trade is live if the drafts get rewritten anyway; if they're supposed to ship close to final, the 3.39-point overall gap is where you'll feel it.

Pick GLM-5.3 if you want the clearly stronger writer, with better tone, cleaner numbers, and far less slop, at about eleven cents per script.
Pick MiniMax M3 if you want scripts at about two cents each with much faster turnaround and can live with a 3.39-point overall gap on drafts you'll edit anyway.
