GeminiTokenCountService

This service is responsible for counting the tokens consumed by a text prompt. It returns an integer indicating the number of tokens consumed by the text prompt.

Token Limit

Token limit is independent of GeminiChat so the use of this feature is not integrated into the use of Gemini

This feature is intended for controlling user token consumption. It uses tables in the database to control usage. Therefore, it is important to publish the respective seeders for its operation.

Command to publish seeder and tables:

To use this feature you need to add the HasGeminiRoles trait to the model user

AssignRole

Can make request?

This function is for check if the user can make request to Gemini according to the established limits. The function returs a boolean value

Is active

This function is for check if the user is active. The function returs a boolean value

The difference between isActive and canMakeRequest is that canMakeRequest works based on the limit of tokens and daily and monthly requests and isActive is a more manual and controlled way of controlling the use.

Update usage

This method updates gemini usage, increments the request counter, and increments the token counter. As a parameter it receives the number of tokens used by a prompt as an integer.

Store Gemini Request

This function is intended to store data from the request to gemini, this function does not affect the tracking of user usage, it only stores data.

EmbeddingService

This service provides text embedding capabilities using Gemini's text-embedding-004 model.

Basic Usage
