gpt-4o-realtime-previewModel overview
Understand the model before estimating your workload.
Use the model ID gpt-4o-realtime-preview 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-4o Realtime has a published context window of 32,000 tokens. The maximum output for this channel is 4,096 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 a billing unit that is not yet recorded. Do not substitute a text-token estimate for image, audio, video, or document charges.
A missing rate is not free usage
If a price, discount, or limit is marked not published, confirm it with the provider before estimating spend. The calculator does not invent a separate cache discount when no cached-input rate is available.
Check discounts and rate tiers
No batch multiplier is applied to the examples on this page. Check the pricing source before assuming an asynchronous job receives a discount. 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.
