GLM 4.5V vs Grok 4.6
Grok 4.6 leads GLM 4.5V on the Artificial Analysis Intelligence Index, 44.3 to 7.6, and GLM 4.5V costs 3.3x less per output token ($1.80 vs $6.00 per million). Updated October 21, 2026; 33 benchmarks have a result for both.
GLM 4.5V or Grok 4.6: which to pick
Only Grok 4.6 has a coding score, 65.7 on the Vibe Coding Index; GLM 4.5V has none, so the two cannot be ranked on coding.
Pick GLM 4.5V for output tokens 3.3x cheaper ($1.80 vs $6.00 per million).

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
GLM 4.5V costs less

50K input + 3K output tokens
GLM 4.5V costs less
Agent loop
200K input + 10K output tokens
GLM 4.5V costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.

Questions
Is GLM 4.5V better than Grok 4.6 for coding?
Only Grok 4.6 has a coding score, 65.7 on the Vibe Coding Index; GLM 4.5V has none, so the two cannot be ranked on coding. Pick GLM 4.5V for output tokens 3.3x cheaper ($1.80 vs $6.00 per million).
Which is cheaper, GLM 4.5V or Grok 4.6?
GLM 4.5V costs $0.60 per million input tokens and $1.80 per million output tokens; Grok 4.6 costs $2.00 and $6.00. Cost per solved task is known for Grok 4.6 only.
Which has the bigger context window, GLM 4.5V or Grok 4.6?
Grok 4.6, with 500K tokens against 66K.
How many benchmarks is the GLM 4.5V vs Grok 4.6 comparison based on?
33 benchmarks have a result for both models as of October 21, 2026. GLM 4.5V's coding index rests on 0 independent benchmarks and Grok 4.6's on 6. Where only one model has a result, the page says so instead of naming a winner.
