GLM-5V-Turbo· GPT-4.1 nano

Quick Verdict

Pick GLM-5V-Turbo if you want the stronger benchmark profile. GPT-4.1 nano only becomes the better choice if you want the cheaper token bill or you need the larger 1M context window.

GLM-5V-Turbo is clearly ahead on the aggregate, 58 to 44. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GLM-5V-Turbo's sharpest advantage is in agentic, where it averages 58 against 47.4. The single biggest benchmark swing on the page is OSWorld-Verified, 62.3% to 42%.

GLM-5V-Turbo is also the more expensive model on tokens at $1.20 input / $4.00 output per 1M tokens, versus $0.10 input / $0.40 output per 1M tokens for GPT-4.1 nano. That is roughly 10.0x on output cost alone. GPT-4.1 nano gives you the larger context window at 1M, compared with 200K for GLM-5V-Turbo.

Decision framing

BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.

Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
