How OpenAI describes it

“GPT-5.2 is our previous flagship model for complex professional work.”

Pricing

Prices in US dollars per 1M tokens, as OpenAI's official pricing page printed them when they were last verified, on October 26, 2026.

At the calculator's starting volume, 1M input tokens and 200K output tokens with no cache hits, GPT-5.2 costs $4.55: $1.75 for input and $2.80 for output, at the prices above. Same formula as the calculator; change the volume there.

Where this price sits

$1.75 per 1M input tokens is the 43rd cheapest input price of the 77 current models with a verified price on AI Signal, and the 6th of OpenAI's 17. Output costs 8.0× the input price.

Other current models in the GPT-5.2 family:

• GPT-5.2 Pro 400K tokens $21.00 in · $168.00 out

Other price lists OpenAI publishes for GPT-5.2

The prices above are OpenAI's Standard list, the one the table and the calculator use. OpenAI also sells GPT-5.2 on 3 other lists, each with a condition. Figures and wording are quoted from OpenAI's own pages as read on the date shown; AI Signal computes none of them.

• Batch · half of Standard on every column · wait: results within 24 hours

  Printed for GPT-5.2: $0.875 input, $0.0875 cached input, $7.00 output, per 1M tokens.

  Learn how to use OpenAI's Batch API to send asynchronous groups of requests with 50% lower costs, a separate pool of significantly higher rate limits, and a clear 24-hour turnaround time. Batches that do not complete in time eventually move to an expired state; unfinished requests within that batch are cancelled

• Flex · half of Standard on every column, the same figures as Batch · accept slower responses and occasional unavailability

  Printed for GPT-5.2: $0.875 input, $0.0875 cached input, $7.00 output, per 1M tokens.

  Flex processing provides lower costs for Responses or Chat Completions requests in exchange for slower response times and occasional resource unavailability. Due to slower processing speeds with Flex processing, request timeouts are more likely.

• Fast mode · double Standard on every column, except the GPT-4.1 and GPT-4o models, which the page prices at less than double · pay more to be scheduled first

  Printed for GPT-5.2: $3.50 input, $0.35 cached input, $28.00 output, per 1M tokens.

  Priority processing was renamed Fast mode on July 30, 2026. If your traffic ramps too fast, the system may downgrade some Fast mode requests to standard speeds and charge standard rates.

Questions about GPT-5.2 pricing

How much does GPT-5.2 cost per million tokens?

$1.75 per 1M input tokens and $14.00 per 1M output tokens, read on OpenAI's official pricing page on October 26, 2026.

What does a cached input token cost on GPT-5.2?

$0.175 per 1M cached input tokens, 10% of the $1.75 input price.

Added on 2026-10-26 (task 338). Price read on 2026-10-26 on OpenAI's pricing page, in its folded 'All models' table, which the page draws in the browser and its Markdown version (developers.openai.com/api/docs/pricing.md) prints; Standard table, columns Model, Input, Output, Cached input, per 1M tokens: 'gpt-5.2 | $1.75 | $14.00 | $0.175 |'. Its model page (developers.openai.com/api/docs/models/gpt-5.2), read the same day, prints 'Input $1.75 Cached input $0.175 Output $14.00', '400,000 context window', '128,000 max output tokens' and 'Aug 31, 2025 knowledge cutoff'. The release date is the date of its only snapshot, 'gpt-5.2 gpt-5.2-2025-12-11'. OpenAI's deprecations page (read 2026-10-26) does not list it.
