Benchmark data for GPT-5 nano and Sakana Fugu Ultra is coming soon on BenchLM.
BenchLM does not have sourced benchmark coverage for GPT-5 nano yet. This comparison is currently limited to metadata such as context window, reasoning mode, and pricing where available.
Sakana Fugu Ultra is priced at $5.00 input / $30.00 output per 1M tokens, versus $0.05 input / $0.40 output per 1M tokens for GPT-5 nano. Sakana Fugu Ultra has the larger context window at 1M, compared with 400K for GPT-5 nano.
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-5 nano: $0.05 input / $0.40 output per 1M tokens Sakana Fugu Ultra: $5.00 input / $30.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
