Overview

OpenAI: GPT-6 Luna is a large language model API from OpenAI, part of its GPT-6 Luna model family. At $0.100 per million input tokens and $0.500 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 5× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. An exceptionally large 1.05M-token context window (≈1,575 pages of text) means entire repositories or document collections can be processed without chunking. Beyond plain text it also accepts File, Image input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 38 (B 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.
