Benchmark data for GPT-5.4 mini and GPT-5.6 Terra is coming soon on BenchLM.
BenchLM does not have sourced benchmark coverage for GPT-5.6 Terra yet. This comparison is currently limited to metadata such as context window, reasoning mode, and pricing where available.
GPT-5.6 Terra is priced at $2.50 input / $15.00 output per 1M tokens, versus $0.75 input / $4.50 output per 1M tokens for GPT-5.4 mini. GPT-5.6 Terra has the larger context window at 1M, compared with 400K for GPT-5.4 mini.
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-5.4 mini: $0.75 input / $4.50 output per 1M tokens GPT-5.6 Terra: $2.50 input / $15.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
