GPT-5.5 Pro and Holo3-35B-A3B finish on the same provisional overall score, so this is less about a single winner and more about where the edge shows up. The provisional headline says tie; the benchmark table is where the real choice happens.
GPT-5.5 Pro is the reasoning model in the pair, while Holo3-35B-A3B is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-5.5 Pro gives you the larger context window at 1M, compared with 64K for Holo3-35B-A3B.
GPT-5.5 Pro and Holo3-35B-A3B are tied on the provisional overall score, so the right pick depends on which category matters most for your use case.
GPT-5.5 Pro has the edge for agentic tasks in this comparison, averaging 90.1 versus 82.6. Holo3-35B-A3B stays close enough that the answer can still flip depending on your workload.
