Why this status

Every value this record asserts — date (March 14, 2023) and context window (8,192) — was found in an archived primary source, checked 2026-08-10. Parameter count is not recorded, so nothing is claimed about it. Capabilities evidenced from the primary sources: vision: “GPT-4 is a large multimodal model (accepting image and text inputs, emitting text outputs) that, while less capable than humans in many real-world scenarios, exhibits hum”.

Pricing

The price a lab's own page showed on the day that page was captured. That is what a snapshot can prove; it is not necessarily the launch price, and prices are often cut later. Citing the live pricing page instead would give a number with no date at all.

Input $30 per million tokens observed February 22, 2026 · archived snapshot (2026-02-22)
Output $60 per million tokens observed February 22, 2026 · archived snapshot (2026-02-22)

Current information, elsewhere

This record is a historical one: every figure above is traced to a dated primary source. For what is true today — live pricing, current rankings, availability — these are better maintained than anything here could be.
