Overview

OpenAI: GPT-5.2 is a large language model API from OpenAI, part of its GPT-5.2 model family. With $1.75 per million input tokens and $14.00 per million output tokens, it is a premium-tier model where output volume is the main cost to watch. 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 File, Image input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 42 (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.
