Models

Note: To provide the best possible response, Instant may occasionally auto-select Thinking for more complex tasks. When this happens, you will be charged at the GPT-5.5 Thinking rate. This will show up in the analytics dashboard as "gpt-5.5-auto-thinking".

Core ChatGPT Features

For ChatGPT Edu customers, the following usage is included at no additional cost and does not consume credits:

• Images: 3 generations per rolling 24-hour period

• Deep research: 5 queries per rolling 24-hour period

The 24-hour period begins at the time of first use. For example, if a user generates an image at 10:00 AM, they can generate 2 additional images until 10:00 AM the following day.

Usage beyond these limits will consume credits according to the rates listed.

ChatGPT for Excel and Workspace Agents

These rates are based on token usage, calculated as credits per 1M input tokens, cached input tokens, and output tokens. For more information about tokens, see: What are tokens and how to count them?.

When this pricing is in effect, ChatGPT for Excel tasks and Workspace Agent runs do not have a fixed credit cost. Credit usage depends on the mix of input tokens, cached input tokens, and output tokens used. The final credit amount can vary by task complexity, input size, the amount of cached input, and output length.

The tables below show credits per 1M tokens for each token type.

Example calculation

If a GPT-5.5 Workspace Agent run uses 20,000 input tokens, 80,000 cached input tokens, and 5,000 output tokens, the run would consume about 7.25 credits:

• Input: 20,000 / 1,000,000 x 125 = 2.5 credits.

• Cached input: 80,000 / 1,000,000 x 12.50 = 1 credit.

• Output: 5,000 / 1,000,000 x 750 = 3.75 credits.

• Total: 7.25 credits.

ChatGPT for Excel/Sheets

A typical ChatGPT for Excel/Sheets task using GPT-5.5 may consume between 5 and 30 credits per task.

ChatGPT Workspace Agents

A typical end-to-end Workspace Agent run using GPT-5.5 may consume between 5 and 25 credits.

Included Rate Limits for ChatGPT Business

Business plans include usage for both ChatGPT Workspace Agents and ChatGPT for Excel - flexible pricing can be used to extend these limits. The included usage is drawn from the general Codex agentic usage pool, and will be effective once flexible pricing takes effect for these features. Read more about Codex usage limits.
