The free usage limit of ChatGPT-4 is calculated based on the number of tokens rather than the number of message lines. 1) New users usually enjoy a free quota of US$5 or equivalent, which can be used for GPT-3.5 or GPT-4 models; 2) The free quota can be converted into thousands to tens of thousands of tokens, depending on the model and content length; 3) API calls are charged per thousand tokens, such as inputting $0.03/1k tokens and outputting $0.06/1k tokens; 4) The web page has limited access rights to some users, and the frequency of use and concurrent requests may be limited; 5) Log in to the OpenAI official website and enter the "Billing" page to view the balance, usage status and validity period; 6) It is recommended to set a budget reminder or turn off automatic renewal to avoid excessive deductions; 7) Ordinary users are not prone to exhaust the free quota without high frequency use on the web page, and developers need to strictly monitor API consumption.

The free usage limit of ChatGPT-4 is not calculated based on the "number of message lines", but is based on the text length processed by the model, which is the so-called "token" number. Each request and reply consumes a certain number of tokens, rather than simply measured by the number of messages.

Currently, the free amount provided by OpenAI is mainly for new users, usually a free amount of US$5 or equivalent RMB (the specific amount may vary by region), which can be used to experience the GPT-3.5 or GPT-4 model. This amount can be converted into about a few thousand to tens of thousands of tokens, depending on the model you are using and the length of the interaction content.

Specific restrictions on free quotas

OpenAI usually provides a certain free call limit for new users after registration. This limit can be used to call the ChatGPT-4 API or interact through official applications for a certain period of time (such as the previous few months).

• API call : If you are a developer and use GPT-4 through the API, then every thousand tokens will have a clear price, for example, the input is $0.03/1k tokens and the output is $0.06/1k tokens.
• Web-side usage (such as chat.openai.com) : Currently, GPT-4 also opens limited access rights to some free users on the web-side, but the frequency of usage and concurrent requests may be restricted.

How to view and manage your free quota

If you have registered an OpenAI account and obtained a free credit, you can view the remaining ones in the following ways:

• Log in to OpenAI official website
• Go to the "Billing" page
• View current account balance, used limit and validity period

It should be noted that once the free amount is used up, the system will automatically switch to the payment mode (provided that you have bound the payment method). In order to avoid accidental deductions, it is recommended to set up a budget reminder or turn off the automatic renewal function.

Let's summarize

ChatGPT-4 does not directly stipulate the free limit on “how many messages can be sent per day”, but rather controls resource consumption through the number of tokens. For ordinary users, as long as they do not have high frequency and long conversations during use on the web, they will not easily exhaust the free credit in the short term; for developers or enterprise users, they need to monitor API usage more carefully.

Basically, that's enough.
