The provider pricing page that our daily tracker reads for this model.
Fetches the official Markdown twin (gpt-5.3-codex.md, text/markdown), which returns Markdown for any Accept header. The bare page URL returns the same bytes only when the Accept header lists text/markdown (the tracker's default header does); with Accept */* or a browser's text/html it returns the HTML page, which shows the same Text tokens values. Prices come from the first 'Text tokens' table under '## Pricing'. That table is the Standard tier: on 2026-10-08 the rate card (pricing.md, Standard 'Grouped Pricing Table data', Codex row) had the same three values, and its Fast table had a higher row. The Markdown twin drops the HTML tier tabs: on pages with several tiers (for example o3.md) each tier is an unlabeled '### Text tokens' table, Standard first. The 'Quick comparison' table repeats the row and also lists GPT-5.2-Codex; the recipe does not read it. The model is deprecated: the HTML page shows a Deprecated badge, and the deprecations page lists shutdown on 2027-04-01 with gpt-6-sol as the replacement. Retired model pages such as gpt-4.5-preview.md keep their Text tokens table, so after the shutdown this source will probably keep reporting the last listed price.
