How to build an image generation AI Agent using Tars?

OpenAI’s image generation models have come a long way. While tools like Midjourney are great for producing artistic visuals, they often miss the mark when it comes to rendering clean, readable text within images. Signs become unreadable. Brand names get jumbled. OpenAI’s recent models, on the other hand, do a much better job with text consistency, making it a solid choice if you need usable images with specific design details.
But here’s the real question: how do you make use of this tech? After the initial wave of fun experimentation, instead of writing the same prompt repeatedly or explaining the goal to an AI model each time, you can build an Agent that streamlines the process.
Putting theory into practice: Meet StyleSwap
Our in-house AI wizard, Gaurav, built StyleSwap. The concept is simple: users upload any photo, select their preferred artistic style, and receive a transformed image within seconds.
StyleSwap reliably produces transformations in styles like:
- Studio Ghibli: Captures the soft, dreamlike quality of Miyazaki’s animation.
- Disney Character: Maintains facial features while adding that distinctive Disney charm.
- Pop Art: Bold colors and high contrast in the style of Warhol or Lichtenstein.
- Van Gogh: Swirling brushstrokes and vivid color palettes.
The list doesn’t end here; there are many more styles incorporated. To find out, check out the Agent for yourself:
This approach works for many applications:
- Online stores showing products in different styles
- Marketing agencies offering new services
- Personal branding help
- Character creators for games
The possibilities are endless. Once you define the imagery style and build the Agent, you can use it endlessly to create imagery without worrying about the right prompt and configurations every time. You can even choose to create a purely generative Agent.
How can you build an image generation AI Agent?
Ready to build your image generation AI Agent? Here’s a step-by-step approach:
Step 1: Define what you’re building
Start by figuring out what kind of Agent you want to create. Are you building something for stylized product images, personal avatars, or character designs for a game? Once that’s clear, create a prompt that suits the use case. If you’re not sure how to write a good prompt for an Agent, here’s a quick guide: How to master prompting and build super cool AI Agents?
Step 2: Add the tool
- Log in to your Tars dashboard
- Head to the Tools section
- Click “Add Tool” and choose the OpenAI Image Generation tool
- Add your OpenAI API key when prompted
That’s it. The tool is now ready to be used inside your Agent. If you want to add a custom Tool, this guide will help you: How can you add tooling capabilities to AI Agents?
Step 3: Build and connect
In the canvas, add an AI Agent Gambit and enter your prompt there. Configure the Gambit as per your requirements. Next, add a Tool Gambit, select the OpenAI Image Gen tool, and connect it to the AI Agent Gambit. Once linked, your Agent will be able to generate images based on the uploaded inputs and the prompt logic.
Step 4: Test and share
Try it out with a few images. If the outputs aren’t quite right, tweak the prompt until it works well. You can also share the Agent internally with your team or use it as part of a larger product flow. It’s flexible enough to support different styles and use cases.
Conclusion
If you’ve been using image generation tools manually until now, writing the same prompt repeatedly, or explaining your idea every time, this is your way out.
With a bit of setup, you can build a personalized Agent that handles all of that for you. It saves time, removes the guesswork, and lets you stay focused on creating great visual outputs. Whether you’re using it for work, your brand, or just for fun, it’s a simple and efficient way to bring AI-generated imagery into your workflow.
