GLM 4.5V vs LongCat 2.0
LongCat 2.0 leads GLM 4.5V on the Artificial Analysis Intelligence Index, 19.1 to 7.6, and LongCat 2.0 costs 1.5x less per output token ($1.20 vs $1.80 per million). Updated October 21, 2026; 4 benchmarks have a result for both.
GLM 4.5V or LongCat 2.0: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GLM 4.5V for work measured by AA Intelligence Index or GPQA Diamond (Artificial Analysis run), where it leads.

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
LongCat 2.0 costs less
Repository review
50K input + 3K output tokens
LongCat 2.0 costs less
Agent loop
200K input + 10K output tokens
LongCat 2.0 costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.
