Set your own OpenAI API Key, so that your account is charged for the use. If you don't have an OpenAI API Key, register to OpenAI Platform and create an API Key.
You can optionally set the API Key via the apikey URL argument and save as a bookmark or to the desktop, but be careful not disclosing it to others.
The URL arguments darkmode and markdown can be used for respective setting. Set to '1' or 'true' to activate.
Only JSON will save settings, so preferably use that format for archiving and continuation of conversations, while the other formats are better suited for presentation. Also CSV can be uploaded again, but without settings.
Hover over settings and buttons for a more thorough description.
Write your prompts as tasks rather than as questions.
Be as descriptive and clear as possible and spell correctly to avoid confusion.
You can continue conversations knowing that GPT is aware of the previous prompts and responses.
Extract from OpenAI's information:
GPT-3.5 Turbo: More likely to follow just one part of a complex multi-part instruction. GPT-3.5 Turbo returns outputs with lower latency and costs much less per token.
GPT-4: Generally performs better on a wide range of evaluations. In particular, it's more capable at carefully following complex instructions. It's also less likely to make up information, a behavior known as "hallucination".
The following value indicates how many tokens a complete conversation can have, including previous prompts and responses.
User: Provides requests or comments for the assistant to respond to.
System: Sets the behavior of the assistant. For example, you can modify the personality of the assistant or provide specific instructions about how it should behave throughout the conversation. If used, write this first in a new conversation.
Assistant: Used by the GPT responses, but can also be written by you to give examples of desired behavior.
