A creator runs 23 side-by-side game and app builds across Qwen 3.8, GPT 5.6 Soul, Fable 5, and Kimi K3. Qwen 3.8 — a 2.4-trillion-parameter model that its makers are preparing to release as open weights — wins on graphics and creativity but trips on controls and physics. Fable 5 stays the reviewer's overall favorite, with Kimi K3 a close second on UI polish and physics.

## Key Takeaways

- **Qwen 3.8 is a 2.4-trillion-parameter model** that its makers position as "second only to Fable 5" and are preparing to release as open weights.
- **Qwen led on graphics and creativity** across the ~23 vibe-coded builds — winning the Outrun, GTA-style, Dragonfly, and landing-page tests — but consistently shipped worse controls, camera angles, and gameplay feel.
- **Fable 5 remained the reviewer's overall favorite** for UI polish and the Remotion video trailer; it struggled on some color-heavy and Skyrim-style builds.
- **Kimi K3 placed a close second**, leading on physics (a movable cloth simulation), fireworks, and Dragon Realm, and is credited with topping front-end coding benchmarks.
- **GPT 5.6 Soul landed mid-pack** — solid camera and controls on some RPG builds, but the weakest Skyrim example and a very basic, AI-looking landing page.
- **Practical friction with Qwen:** Qwen.com is region-locked (unreachable from the UK) and the international API wouldn't connect, so testing ran through Koda/QD. The reviewer's verdict is "test it yourself" — other reviewers on X rated Qwen far lower.
