01What Antigravity Claude 5.5 Is and How It Works

Antigravity Claude 5.5 is a powerful combination where the Antigravity platform now includes Claude Opus and Sonic 5.5 models. This means you can build websites and apps using these advanced AI models directly inside Antigravity. It works by letting you choose a model like Opus 5.5 or Sonic 5.5, then you give a simple prompt, and Antigravity does the building for you.

The process is simple: pick a model, write what you want, and let the AI create the design. You can watch it work in real time, make changes, and even schedule tasks to run on their own. This makes building beautiful websites easier than ever, even for beginners.

02Main Features of Antigravity with Claude 5.5

Antigravity with Claude 5.5 brings several key features that improve your building experience. First, you can switch between models like Opus 5.5 and Sonic 5.5 anytime. This is useful because Opus is often better for design, while Sonic is faster.

  • Model switching lets you try different AIs without starting over.
  • Scheduled tasks let you set jobs that run in the background.
  • Conversation history keeps your past work easy to find.
  • Custom skills and MCPs let you add extra tools and plugins.
  • Turbo mode reduces approval prompts for faster work.

These features make Antigravity flexible and powerful, whether you're a beginner or a pro.

03How to Set Up Antigravity with Claude 5.5

Getting started with Antigravity and Claude 5.5 is straightforward. Just follow these steps:

  1. Open Antigravity and make sure you have the latest version.
  2. Go to the model selector and choose Claude Opus 5.5 or Sonic 5.5.
  3. If you're unsure, pick Opus 5.5 for the best design quality.
  4. Choose a setting like 'Medium' for a good balance of speed and quality.
  5. Create a new conversation or project, depending on what you're building.
  6. Write your prompt describing the website or app you want.

That's it. Once you submit your prompt, Antigravity will start building. You can watch the progress and make changes as needed.

04How to Use It: Walking Through the Episode's Examples

In the episode, Julian Goldie showed a live test. He gave the same prompt to Antigravity and Claude Desktop: 'Build a new website for AIprofitboardroom.com, make it look beautiful, interesting, modern, elegant.'

In Antigravity, he started a project, chose Opus 5.5, and let it work. The first draft was not great, but after he asked for more interesting design, the output improved dramatically. He saw 3D designs, animated charts, and a cleaner layout.

He also set up a scheduled task to run in the background, so Antigravity works while you do other things. And he showed how to create a new project, like a mission control dashboard, with a simple prompt.

Remember, Antigravity asks for approval on some actions. You can turn that off in the settings or use Turbo mode for a smoother flow.

05Results: Antigravity vs Claude Desktop Test

Julian ran a side-by-side test between Antigravity with Opus 5.5 and Claude Desktop with Opus 5.5. The results were surprising. The design from Antigravity looked much nicer than Claude Desktop's.

Claude Desktop produced a purple gradient style that felt a bit 'AI sloppy.' The fonts and layout were basic. Antigravity's version had better fonts, a more elegant style, and even included custom tools and testimonials.

However, Julian noted that Antigravity still makes up testimonials sometimes, like Claude does. But overall, the output quality was clearly better with Antigravity. It was also faster to respond than Claude Desktop.

This shows that the platform you use matters, not just the model.

06Tips, Limits, and Mistakes to Avoid

Here are some tips and warnings from the episode to help you get the most out of Antigravity with Claude 5.5.

  • First drafts may be poor—be ready to give feedback and request changes.
  • Opus 5.5 is slower than Sonic 5.5, so choose based on your need for speed.
  • Set up Turbo mode to avoid approval prompts, but only if you're comfortable with less control.
  • Use projects for important work; conversations are more temporary and hard to find later.
  • Be careful with access rules if you allow everything, as it might lead to unintended actions.

Also, note that Antigravity might sometimes reset your model choice to Sonic. Check your settings if that happens.

07Who It Is For and Why It Matters

Antigravity with Claude 5.5 is for anyone who wants to build websites or apps without coding. It's beginner-friendly, much easier than using Claude Code directly. If you want fast, beautiful designs with just a prompt, this is for you.

It matters because it saves time and money. If you run out of tokens on Claude, you can switch to a different model inside Antigravity without paying for another account. You can also schedule tasks to run while you do other things, making you more productive.

Julian also mentioned that Antigravity is a great harness for future models like Gemini 4, so it's a tool worth learning now.

08Why Antigravity Beats Claude Desktop for Design

The test in the episode proved that Antigravity with Opus 5.5 produces better-looking websites than Claude Desktop. The fonts, the layouts, and the overall style were more elegant and modern. Julian said the difference was 'ten times nicer.'

This is because Antigravity has a built-in design system that enhances the output. It also allows you to switch models easily, which can improve results. If you're tired of basic AI designs, try Antigravity.

Remember to give feedback if the first result isn't perfect. Ask for changes and let the AI refine it. With a few rounds, you can get a professional-looking site.

09How to Schedule Tasks and Keep Building

One hidden trick from the episode is scheduling tasks in Antigravity. You can set a task, choose a schedule, pick a project, and let it run in the background. This is great for ongoing work like content updates or research.

To do it, go to the schedule tasks section, write your prompt, set the time, and submit. Antigravity will handle it while you do other things. This makes it feel like you have a little helper working around the clock.

It's similar to tools like OpenClaw or Hermes Agent, but built into Antigravity. This feature saves time and keeps your projects moving.
