GPT-6 Sol and Luna vs Claude Opus 5.5: this real Figma MCP test compares which new AI model is most useful for UI/UX designers, product designers, and design-to-code workflows.
Using the Material 3 Figma design system, I gave OpenAI GPT-6 Sol, GPT-6 Luna, and Anthropic Claude Opus 5.5 the same prompt: inspect a real design system through Figma MCP and generate a responsive HTML prototype for a SaaS team-members settings page.
This is a practical AI model comparison for designers—not another review based only on benchmarks.
I compare:
- GPT-6 Luna’s speed and efficiency
- GPT-6 Sol’s design judgment and implementation quality
- Claude Opus 5.5’s visual design and session usage
- Figma design-system fidelity
- Design tokens, colors, spacing, typography, and components
- Figma-to-HTML and design-to-code accuracy
- Responsive desktop and mobile layouts
- Search, filtering, roles, account status, and invite-modal interactions
The results were surprisingly close. GPT-6 Luna and GPT-6 Sol generated nearly identical interactive prototypes, while Claude Opus 5.5 created a more visually elegant UI but consumed substantially more of my available session usage.
If you use ChatGPT, Claude, Figma MCP, Claude Code, Codex, or AI coding tools for product design and frontend prototyping, this designer-focused test shows how the latest models perform on a realistic design-system workflow.
Which AI model would you choose for UI design and design-to-code work: GPT-6 Luna, GPT-6 Sol, or Claude Opus 5.5?
