Why this status

Every value this record asserts — date (2026-03-05) and context window (1,050,000) — was found in an archived primary source, checked 2026-08-10. Parameter count is not recorded, so nothing is claimed about it. Modalities taken from the documentation's own declaration: "Input Text, image Output Text". Capabilities evidenced from the primary sources: vision: “Modalities Text Input and output Image Input only Audio Not supported Video Not supported” | reasoning: “Reasoning token support”.

GPT-5.4 supports a context window of 1,050,000 tokens.

ParametersNot disclosed

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 $2.5 per million tokens observed March 5, 2026 · archived snapshot (2026-03-05)
Output $15 per million tokens observed March 5, 2026 · archived snapshot (2026-03-05)

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.

What changed from GPT-5.2

Compared with the previous release in this series. A field appears only when both records state a value — where one does not, it is listed as uncomparable rather than dropped, because a gap in our research is not a finding about the model.
