gpt-5.3-codexModel overview
Understand the model before estimating your workload.
Use the model ID gpt-5.3-codex through the provider's direct API. The prices and limits on this page apply to that specific listing, with source data checked on 2026-10-12.
GPT-5.3-Codex has a published context window of 400,000 tokens. The maximum output for this channel is 128,000 tokens. Budget context space for your prompt, conversation history, retrieved material, and the response. Context capacity and output limits are different; your input and response must fit within the request limits. A larger window does not make those tokens free.

How billing works
The details that turn a token rate into an actual bill.
Use the published billing unit
This model uses / 1M tokens. Do not substitute a text-token estimate for image, audio, video, or document charges.
Cache hits have their own rate
The listed cached-input price is $0.175 per million tokens. Reusing a prompt does not automatically qualify: use the provider's reported cached-token count, and account for any cache-write or storage charges.
Check discounts and rate tiers
Eligible batch requests use 50% of the standard token rate in this listing. Batch work is asynchronous; check supported endpoints and turnaround times. Review the provider's pricing terms for workload-specific conditions.
Account for the complete workflow
Retries, follow-up calls, and agent tool loops increase request counts. Search, storage, and other tool charges can be billed separately from model inference. Use actual API usage logs to calibrate a budget before scaling traffic.
