# Free vs. Paid AI Agents

A Comprehensive Guide to Understanding the Costs of AI Agents and How to Manage Your Balance

### Overview

MindStudio makes it easy to access powerful AI capabilities—without hidden fees or upfront commitments. This guide explains which AI Agents are free to use, how paid agents work, and how to manage your usage balance.

### **Free AI Agents**

MindStudio offers a range of powerful AI Agents that you can use entirely for free. These agents feature workflows designed to efficiently handle more basic tasks. Their simplified processes result in shorter run times, which helps keep the service free for users.

Here are a few examples of free AI agents:

* **Research Agents**

  Fact-check sources, find similar products, and uncover emails in one click.
* **Content Analysis Agents**

  Summarize, simplify, or de-bias long articles and videos instantly.
* **Content Creation Agents**

  Generate tweets, LinkedIn posts, YouTube ideas, and more—on demand.
* **Image Generation Agents**

  Create icons, illustrations, thumbnails, and other visuals in seconds.

### **Paid AI Agents**

MindStudio also offers AI Agents that leverage complex AI models, advanced workflows, and sometimes even integrate custom data. This additional complexity means these agents are more costly to run.

Here are some examples of tasks run by paid AI agents:

* Running large-scale data analysis
* Using advanced or premium AI models
* Integrating external services and APIs
* Performing long-running or high-volume tasks

To run these agents, you'll need to have a balance in your MindStudio account.

### **Identifying Free vs. Paid AI Agents**

To tell free agents from paid ones, look for a small label beneath each Agent’s **Run** button. If you see a **“Paid Agent”** label, running it will deduct from your balance; if there's no label, the Agent is completely free to use.

This indicator appears on both the **MindStudio Agents page** and the **Chrome Extension**, so you can confidently browse and try out different Agents knowing exactly which ones are free and which ones require payment.

#### Example:

In the image below, **Deep Research** and **Research People** are marked as Paid Agents, while others like **Find Product Alternatives** and **TL;DR** are free to use.

### **The Prepaid Balance**

MindStudio uses a **prepaid balance system** for running paid AI Agents. Your balance is deducted based on the actual costs of model inference and execution.

#### Adding Funds to Your Balance

In your Workspace, navigate to **Billing** > **Balance**, then select **Add Funds** to choose an amount and payment method.

**Cost of Running Paid AI Agents**

The cost per run varies depending on the specific agent and the amount of data processed. Each paid agent displays a cost estimate on its details page, along with an average run time.

### **No More Usage Fees for Developers**

If you're building your own AI Agents in MindStudio, we’ve removed the **2.9% processing fee** previously charged on model usage. That means:

* You only pay for model inference costs.
* No API key management required.
* More freedom to experiment and iterate.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://university.mindstudio.ai/free-vs.-paid-ai-agents.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
