GPT-5.4 Pro and Thinking are here!

The missing rows of “pricing”: Model | Input | Cached input | Output ---|---|---|--- gpt-5.4 (<272k context length) | $2.50 | $0.25 | $15.00 gpt-5.4-pro (<272k context length) | $30.00 | | $180.00 gpt-5.4 (>272k context length) | $5.00 | $0.50 | $22.50 gpt-5.4-pro (>272k context length) | $60.00 | | $270.00 Large context is not a progressive tax: it is a switch to the higher price with input larger than 272000 tokens (not 1024 * 272). Also, review the “vision” - the image resolution at defaults has a higher cap - 1536 → 2500 “patch” tokens, equivalent to an area 1600x1600px, so you may want to especially consider getting resizing under your control before sending to API.
