# Costs and Limits

At the moment our services are free to the community, however we apply usage limits to manage overall costs and guarantee fair usage for everyone in the Brown community.

## Transcribe

### Per-user limit (daily)

Each user can upload and transcribe **20 hours** of audio/video files each day. Once the limit is reached, the users will not be able to submit transcription jobs. **This limit resets at 0:00 UTC each day.**

### System-wide limit

Transcribe does not have any system-wide limit at the moment.

## LibreChat

### Individual Limits (Monthly)

Individuals have a budget of **twenty dollars ($20) per month**. In practice, this budget is converted into tokens. Models have different costs. We label them in the UI with three different categories, $, $$, $$$ to provide guidance on the cost of the model. Cost for the month align with calendar months **(limits reset on the 1st of each month)**.

### System wide limit (Monthly)

We have total budget allocated to the system. Users will not be able to use the system if they have reached their individual limit, or if as an university we have reached the system limit. Cost for the month align with calendar months (limits reset on the 1st of each month).

### Purchasing additional tokens

We do not have that capability at this time.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ccv.brown.edu/ai-tools/costs-and-limits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
