GLM 5.1 vs Nemotron 3 Super
GLM 5.1 leads Nemotron 3 Super on the Artificial Analysis Intelligence Index, 26.1 to 12.8, and Nemotron 3 Super costs 9.8x less per output token ($0.45 vs $4.40 per million). Updated October 22, 2026; 39 benchmarks have a result for both.
GLM 5.1 or Nemotron 3 Super: which to pick
Only GLM 5.1 has a coding score, 49.2 on the Vibe Coding Index; Nemotron 3 Super has none, so the two cannot be ranked on coding.
Pick Nemotron 3 Super for output tokens 9.8x cheaper ($0.45 vs $4.40 per million) and a larger context window (262K against 205K tokens).
