Pick GPT-5.4 Pro if you want the stronger benchmark profile. Ornith-1.0-35B only becomes the better choice if you want the cheaper token bill.
GPT-5.4 Pro is clearly ahead on the provisional aggregate, 90 to 67. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.4 Pro's sharpest advantage is in agentic, where it averages 89.3 against 64.2.
GPT-5.4 Pro is also the more expensive model on tokens at $30.00 input / $180.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Ornith-1.0-35B. That is roughly Infinityx on output cost alone. GPT-5.4 Pro gives you the larger context window at 1.05M, compared with 262K for Ornith-1.0-35B.
GPT-5.4 Pro is ahead on BenchLM's provisional leaderboard, 90 to 67.
GPT-5.4 Pro has the edge for agentic tasks in this comparison, averaging 89.3 versus 64.2. Ornith-1.0-35B stays close enough that the answer can still flip depending on your workload.
