Benchmark data for GPT-OSS 20B and o3 is coming soon on BenchLM.
BenchLM does not have sourced benchmark coverage for GPT-OSS 20B and o3 yet. This comparison is currently limited to metadata such as context window, reasoning mode, and pricing where available.
o3 is priced at $10.00 input / $40.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for GPT-OSS 20B. o3 has the larger context window at 200K, compared with 128K for GPT-OSS 20B.
Not fully yet. BenchLM is tracking both models, but the sourced benchmark breakdown for this comparison is still coming soon.
BenchLM only shows category winners and benchmark-level calls when we have sourced results that can be compared fairly. For these models, the public benchmark coverage is not complete enough yet.
GPT-OSS 20B: $0.00 input / $0.00 output per 1M tokens o3: $10.00 input / $40.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
