    Claude Opus 5.5 vs Fable 5.1: 3D Websites from One Prompt

    Anthropic's new Claude Opus 5.5 against the far more expensive Fable 5.1, and Opus 5.5 on high effort against max effort. The websites in the video each came from one prompt with no design direction: an architecture studio inspired by an award-winning site, a space agency, a strawberry drink launch and a luxury watch reveal, plus IRONFALL, a full 3D shooter game. Here are the exact five prompts, so you can run the same test yourself.

    WHAT YOU'LL NEED

    Prerequisites

    • ▸Claude Code with Claude Opus 5.5 (run it on high effort, then max effort, to compare)
    • ▸The Higgsfield MCP connected, with Nano Banana Pro for images, Seedance 2.5 for video and some generation balance (every prompt asks for the cost and waits for your OK first)
    • ▸A modern browser with WebGL to view the sites, on desktop and on your phone
    Each prompt is complete on its own. Run any of them in a fresh project.
    Part 01 / 03

    From an award-winning site

    The agent gets an award-winning site as inspiration and builds an architecture studio. Everything else is the model's call.

    PROMPT 1

    An architecture studio, inspired by an award-winning site

    Claude Code with Claude Opus 5.5 and the Higgsfield MCP · Inspiration site

    The agent gets an award-winning site as inspiration and builds an architecture studio website.

    The agent gets an award-winning site as inspiration and builds an architecture studio website.

    See what it built: KAST (Claude Opus 5.5, high effort) and STRATA (Fable 5.1, same prompt).

    Build a website for a fictional architecture studio, using https://landonorris.com/ as your inspiration.
    
    I'm deliberately giving you no design direction: every creative decision is yours, and this is a test of what you can do. What I want is a website that is extremely beautiful, interactive and cinematic, the kind that wins awards and makes people say wow. Use three.js or whatever tools you need to create a captivating 3D experience with scroll animations and scroll interactions. It must never feel boring or like a template.
    
    Create the images with the Higgsfield MCP using Nano Banana Pro, and the videos with Seedance 2.5. Before generating anything, tell me what you plan to generate and what it will cost, and wait for my OK.
    
    It has to work beautifully on phones too. Check it yourself before you tell me it is done.

I want it to feel like a real, polished console game that people can't stop playing and want to show their friends: great to look at, satisfying to shoot, with real animated characters, cinematic moments, sound and music, menus, and a proper way to win and lose. Use three.js or whatever tools you need.
