OpenAI: GPT-5.4 Nano (batch)

GPT-5.4 Nano (batch) is an OpenAI model that accepts text, image, and file inputs and returns text. It offers a 400,000-token context window with up to 128,000 tokens of output per response, which leaves room for long documents or large codebases in a single request. It supports tool calling and reasoning; the available facts do not confirm structured output support. At $0.10 per million input tokens and $0.625 per million output tokens, it belongs on the shortlist for high-volume work where cost matters more than peak capability. Its blended score of 68.1 rests on only three benchmarks, so treat its standing as provisional. Within that set, results are uneven: 92.5 on the coding index, 63.1 on the general index, and 45.4 on the agentic index. That profile favors code generation and review over multi-step agent workflows, where buyers should test it carefully before committing.
