Description

A TextGenerator instance lets you use a large language model (LLM) to generate text based on a system prompt from you and a user prompt from the player. The most common use of the API is for creating interactive non-player characters (NPCs).

For example, in a survival experience, your system prompt for a talking animal might be "You are a very busy beaver. You end all statements by mentioning how you need to get back to work on your dam.". Users could ask the beaver about water in the area, the size of a nearby forest, predators, etc.

The novelty of LLM responses can help create unique, delightful moments for players, but using the API effectively requires a bit of creativity and tuning. System prompts can be very extensive, so don't hesitate to include a long string with lots of detail.

Rate limits

Requests are initially limited to 100 per minute, which scales up based on the number of concurrent users.

Properties

Member	Signature	Summary
Seed	Seed: int	Sets a fixed seed for the random number generator, allowing reproducible responses in cases where the same input parameters are used across multiple requests.
SystemPrompt	SystemPrompt: string	Provides context to the model about its role, tone, or behavior during conversation.
Temperature	Temperature: float	Controls the "creativity" or randomness of the model's responses.
TopP	TopP: float	Helps the AI model narrow or expand the range of possible words to sample from while generating the next token.
