About this video

Gemini 4 just launched and the frontier model race is now a four-horse race.

I tested Gemini 4, Opus 5.5, GPT-6 Astra, and Muse Wonder across five real use cases: 3D models, games, animated shorts, website design, and writing.

What I cover: (00:00) Four frontier models build Himeji Castle in code (00:43) Test 1: Himeji Castle in Blender with music (03:46) Test 2: A Star Fox x StarCraft rail shooter (07:02) Test 3: An animated short that makes you feel something (11:20) Test 4: Which model is best at website design (14:16) Test 5: Testing each model's writing capabilities (16:31) The use case that really surprised me about Gemini 4 (17:45) Recapping the winners for each use case

Prompts I used:

Himeji Castle: "Build Himeji Castle in Blender and render a 30-second cinematic at dawn in cherry blossom season. Get the architecture right and add music you compose in code."

Star Fox x StarCraft: "Build a Star Fox-style rail shooter in three.js, with the ship, enemies, boss, and terrain modeled in Blender. Include a barrel roll, lasers, a boss fight, and a soundtrack."

Emotional short: "Make a 30-second animated short that tells a story and leaves viewers with a strong emotion. Make every frame and sound in code, with no stock assets."

Website redesign: "Redesign the brand and homepage for Behind the Craft, my newsletter, YouTube channel, and podcast. Create a logo, a color and type system, and a homepage that doesn't look AI-generated.

Don't look at my current site."
