GLM 4.6 vs Grok Build 0.1
Grok Build 0.1 leads GLM 4.6 on the Artificial Analysis Intelligence Index, 27.2 to 18.5, at about the same output price ($2.00 vs $2.20 per million). Updated October 21, 2026; 3 benchmarks have a result for both.
GLM 4.6 or Grok Build 0.1: which to pick
Only GLM 4.6 has a coding score, 8.8 on the Vibe Coding Index; Grok Build 0.1 has none, so the two cannot be ranked on coding.
Pick Grok Build 0.1 for output tokens 1.1x cheaper ($2.00 vs $2.20 per million) and a larger context window (256K against 205K tokens).
