OpenAI: GPT-5 Nano (batch)
🇺🇸 OpenAI · GPT-5 Nano
Overview
OpenAI: GPT-5 Nano (batch) is a large language model API from OpenAI, part of its GPT-5 Nano model family. At $0.025 per million input tokens and $0.200 per million output tokens, it sits in the budget tier — among the cheaper options for high-throughput or cost-sensitive workloads. Output tokens cost about 8× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. A large 400K-token context window (≈600 pages of text) lets it take in whole books, large codebases, or lengthy transcripts in a single call. Beyond plain text it also accepts Image, File input, so it can be applied to multimodal tasks rather than text alone. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
