ByteDance BAGEL AI: The Free Alternative to GPT-4 Vision You Can Use Today

ByteDance, the company behind TikTok, just released a powerful new tool in the artificial intelligence world: BAGEL AI. Unlike popular tools like GPT-4 Vision or Google’s Gemini, BAGEL is completely free and open-source.

‍

That means anyone can use it, modify it, and explore its full potential without paying a cent. Whether you're a content creator, developer, or just someone curious about the future of AI, BAGEL offers an exciting glimpse into what's possible with visual AI today.

‍

In this article, Dirox will break down what makes BAGEL so special, how it compares to other top models, and how you can start using it right now.

‍

I. What Is BAGEL AI and What Can It Do for You?

‍

1. The Simple Explanation

‍

‍

BAGEL AI is ByteDance’s response to expensive, commercial AI models like GPT-4 Vision. It’s a multimodal AI, meaning it can handle and understand multiple types of content—especially images.

‍

What makes this generative AI impressive is that it combines image understanding, image generation, and image editing into one single tool. And it can do all of this using simple text commands.

‍

Here’s what BAGEL can do:

‍

Understand images: Ask it questions about a photo, and it can explain what's happening.

Generate images: Give it a description, and it can create an image from scratch.

Edit images: Want to change the background in a photo? Just describe what you want, and BAGEL makes it happen.

Reason about visuals: It can interpret complex visuals like memes, infographics, or scientific diagrams.

‍

The most important part? It’s free and open-source under the Apache 2.0 license, meaning anyone can use and build on top of it.

‍

2. Key Technical Specs (For Tech Users and SEO)

‍

For those who are more technically inclined, BAGEL runs on a 7 billion parameter model, with 14 billion total parameters across a Mixture-of-Transformer-Experts (MoT) architecture. It was trained on trillions of data points from text, images, video, and the web.

‍

Its dual visual encoders let it see the fine details in an image (pixel-level) and also understand the bigger picture (semantic-level). This gives it a powerful combination of low-level accuracy and high-level reasoning.

‍

3. Real-World Applications

‍

For Content Creators: BAGEL makes it easy to generate content for social media, edit product photos, or try out new designs with just a sentence.

For Businesses: It can help analyze image data, generate marketing visuals, or process large sets of visual content automatically.

For Personal Use: Edit family photos naturally (e.g. “make the sky look like sunset”), create personalized illustrations, or even decode complicated diagrams or memes.

‍

‍

‍

II. How BAGEL Compares to Popular AI Models

‍

When it comes to AI tools that understand and generate images, BAGEL isn’t alone. It competes with industry giants like OpenAI’s ChatGPT-4.5 and Google’s Gemini 2.5. So, how does BAGEL stack up?

‍

Let’s look at some of the key differences:

‍

1. Feature Comparison: BAGEL vs ChatGPT vs Gemini

‍

‍

What stands out immediately is BAGEL’s open-source model. Unlike ChatGPT or Gemini, which require subscriptions or developer accounts, anyone can download and use BAGEL freely.

‍

It may not have the massive context window of Gemini, but it does offer a great balance between capability and accessibility.

‍

2. Benchmark Comparisons: Understanding & Generation

‍

To see how these models perform, AI researchers use benchmark tests. These tests check how well a model can understand images and generate them.

‍

‍

‍

‍

BAGEL ranks at or near the top in every category, especially in MMBench and MMVet, which measure how well a model understands images across different tasks. This shows BAGEL’s strong ability to reason visually, not just recognize objects.

‍

‍

‍

BAGEL also performs extremely well in image generation, especially in handling multiple objects, accurate color use, and counting items in scenes.

‍

This makes it an excellent choice for tasks where precision in visuals really matters—for example, product visuals or complex scenes in marketing content.

‍

‍

3. Key Takeaways from the Benchmarks

‍

‍

‍

III. Getting Started: Installation and Real User Experience

‍

If you’re interested in trying out BAGEL AI, you’ll need to make sure your computer can handle it

‍

Unlike cloud-based tools like ChatGPT or Gemini, BAGEL runs locally on your machine, which means it requires powerful hardware and some basic technical knowledge.

‍

1. System Requirements: What You’ll Need

‍

Running BAGEL AI isn’t plug-and-play for most people. Here’s what’s needed:

‍

Minimum setup:
