In the context of RWTHgpt, tokens are the unit with which the AI models used measure the length of texts (both for user-generated questions and system-side answers).
These are frequent character strings that occur in a text. The division into tokens is complicated and is not uniformly based on words or characters.
Detailed information on calculating the number of tokens and the background can be found here:
- OpenAI GPT Token Guide (DE)
- What are Tokens
OpenAI itself offers a calculator that makes it possible to determine the number of tokens and calculation in sentences or texts:
- Tokenizer

There is a general token limit for chats with RWTHgpt, which can vary depending on the selected language model or AI tool.
The maximum number of tokens that can be used, as well as the number of tokens used so far, is displayed below the text input field.
As soon as the token limit is reached, either open a new chat or edit prompts.
Individual entries (text & image) have no additional token limit.
Depending on the selected language model or AI tool, there are also restrictions on the number of prompts per hour. These can be seen when selecting the model.

Now write a prompt that instructs RWTHgpt to analyze the image. You can also set restrictions here.
- For example: “Analyze the attached image (focusing on the font and ignoring colors).
