Pick GLM-5.1 if you want the stronger benchmark profile. Ornith-1.0-9B only becomes the better choice if coding is the priority or you want the cheaper token bill.
GLM-5.1 is clearly ahead on the provisional aggregate, 74 to 52. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GLM-5.1's sharpest advantage is in agentic, where it averages 65.3 against 43.1. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 63.5% to 43.1%. Ornith-1.0-9B does hit back in coding, so the answer changes if that is the part of the workload you care about most.
GLM-5.1 is also the more expensive model on tokens at $1.40 input / $4.40 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Ornith-1.0-9B. That is roughly Infinityx on output cost alone. Ornith-1.0-9B gives you the larger context window at 262K, compared with 203K for GLM-5.1.
GLM-5.1 is ahead on BenchLM's provisional leaderboard, 74 to 52. The biggest single separator in this matchup is Terminal-Bench 2.0, where the scores are 63.5% and 43.1%.
Ornith-1.0-9B has the edge for coding in this comparison, averaging 69.4 versus 60.9. GLM-5.1 stays close enough that the answer can still flip depending on your workload.
GLM-5.1 has the edge for agentic tasks in this comparison, averaging 65.3 versus 43.1. Inside this category, Terminal-Bench 2.0 is the benchmark that creates the most daylight between them.
