OpenAI: GPT-4.1

OpenAI: GPT-4.1 is a large language model API from OpenAI, part of its GPT-4.1 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. An exceptionally large 1.05M-token context window (≈1,571 pages of text) means entire repositories or document collections can be processed without chunking. 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 19 (D grade), a useful proxy for its general reasoning strength relative to the other models tracked here.
