# Limits & Warnings

> Platform limits for projects, topics, and users

We enforce some reasonable limits on the data to ensure smooth processing. Most limits can be relaxed if necessary — contact support if you hit a limit that prevents you from completing your analysis.

## Project limits

* 25 "Text to Analyze" columns allowed per project — [contact support](https://caplena.com/en/contact) if you need more
* 200 columns total for file uploads
* 50 MB maximum file size for uploads (no strict size limit for CSV files)
* 500 links maximum when importing via integrations

## Topic limits

* With the **new AI (LLM)**, up to **800 topics** are supported whether or not sentiment is enabled
* With the **legacy AI**, the maximum is **266 sentiment-enabled topics** (up to 800 without sentiment). Switching a project with more than 266 sentiment-enabled topics from the new AI back to the legacy model is not supported
* For semi-open columns this limit can be increased upon request
* Maximum **100 characters** for the topic label
* Maximum **100 characters** for the category label
