GLM 5V Turbo or o4 Mini High: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GLM 5V Turbo for output tokens 1.1x cheaper ($4.00 vs $4.40 per million) and a larger context window (203K against 200K tokens).
No benchmark has tested both yet. GLM 5V Turbo has results on LMArena WebDev, Terminal-Bench Hard (Artificial Analysis run) and LMArena Text: coding; o4 Mini High on ALE-Bench and GDPval. Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.

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 5V Turbo costs less
Repository review
50K input + 3K output tokens
o4 Mini High costs less
Agent loop
200K input + 10K output tokens
o4 Mini High costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.
