Pick GLM-5V-Turbo if you want the stronger benchmark profile. GPT-OSS 20B only becomes the better choice if you want the cheaper token bill.
GLM-5V-Turbo is clearly ahead on the aggregate, 58 to 35. 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 33.1. The single biggest benchmark swing on the page is OSWorld-Verified, 62.3% to 31%.
GLM-5V-Turbo is also the more expensive model on tokens at $1.20 input / $4.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for GPT-OSS 20B. That is roughly Infinityx on output cost alone. GLM-5V-Turbo gives you the larger context window at 200K, compared with 128K for GPT-OSS 20B.
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.
