Overview

OpenAI: GPT-4o-mini is a large language model API from OpenAI, part of its GPT-4o-mini model family. At $0.150 per million input tokens and $0.600 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 4× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. The 128K-token context window — around 192 pages of text — comfortably handles long documents, multi-file code, or extended conversations. Beyond plain text it also accepts Image, File input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 7 (F grade), a useful proxy for its general reasoning strength relative to the other models tracked here. 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.
