Where these figures come from
Every OpenAI figure is read from 4 vendor pages:
- https://developers.openai.com/api/docs/models/text-embedding-3-large
- https://developers.openai.com/api/docs/models/text-embedding-3-small
- https://developers.openai.com/api/docs/pricing
- https://openai.com/api/pricing/
The weekly check re-reads each page and records any change with both the old and new figure. Prices are USD list rates excluding tax; negotiated and volume pricing are not modelled.
