Overview

OpenAI: o3 is a large language model API from OpenAI, part of its o3 model family. Priced at $2.00 per million input tokens and $8.00 per million output tokens, it occupies the mid-range, balancing capability against running cost. Output tokens cost about 4× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. A large 200K-token context window (≈300 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. On Artificial Analysis's Intelligence Index it scores 30 (C 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.
