Guides about rapid evolution of AI, coding agents, and exactly what's moving the industry forward.
Three models built the same pipe-dodging bird flap game with Command Code /design. DeepSeek V4.1-Flash one-shot it clean at $0.0089, the lowest cost of the round - though not the lowest in this benchmark series overall.
One prompt, four models, zero hand-editing. A line-by-line read of what Fable 5.1, GLM 5.3, Kimi K3, and (updated) Qwen-3.8-Max actually shipped when asked to build the same pipe-dodging bird flap game with Command Code /design.
Seven models built the same coin-collecting endless runner with Command Code /design. Opus 5 is the only one that renders real projected 3D - and the only one that forgot to save your high score.

Opus 5, DeepSeek V4 Pro, Fable 5, GLM 5.2, GPT-5.5, GPT-5.6 Sol, Kimi K3, Gemini 3.6 Flash, Laguna S 2.1, and Ling 3.0 Flash all built the same neon brick-breaker. Here is what a line-by-line code read found.
Four models built the same neon Snake game with Command Code /design. We played all four side by side on desktop and mobile - Muse Spark 1.1 won, but not for the reason we expected going in.
Two models built the same minimalist photography portfolio landing page with a 3D floating-frame hero and lightbox gallery, using Command Code /design.

Four models built the same surreal, WebGL-heavy scroll journey with Command Code /design. Fable 5.1 was the most expensive build in the set despite shipping the least code - and the least interaction.
Eight models built the same vertical Galaxy Shooter with Command Code /design. Kimi K3 came out on top on both quality and price, at roughly 167 quality-per-dollar.
Seventeen models generated the same dark, minimalist personal portfolio site with Command Code /design. Kimi K3 wins on both quality and price, at roughly 82 quality-per-dollar.

Four models built the same top-down car racing game with Command Code /design, and this round included an actual manual playtest. GPT-5.6 Sol has the best UI in the set and the worst physics.
Seven models built the same retro pixel-art cave shooter with Command Code /design. DeepSeek is 176x cheaper than GLM 5.2 - and also the only build where you can fly straight through the walls.
Five models rebuilt the classic offline no-internet dinosaur runner game with Command Code /design. The hands-on playtest and the code read disagree on two of the four builds - a good reminder that code polish and game feel are not the same axis.

Start for FreeThree models built the same cinematic, scroll-triggered eco-luxury landing page with Command Code /design. Fable 5 and Kimi K3 wrote within 3% of the same amount of code - Fable 5 still cost 3.2x more.
Four models built the same third-person car racing game with Command Code /design. The code read and the actual playtest disagree on the winner - a clean case study in why craft and feel are different axes.
Four separate /design runs with Kimi K3 in Command Code, posted on X as they happened: a developer portfolio for $0.035, a chase-cam racing game for $0.97, a first-person shooter for $2.10, and a voxel sandbox game for $2.90.

Start for FreeTwo free open-source models were given the same neon brick-breaker prompt with Command Code /design. Both one-shot it clean - a model that usually needs 8-10 iterations for this brief.
Six models, one retro pixel-art space shooter prompt, run across two separate one-shot rounds with Command Code /design - including a genuine guess-the-model challenge.
Four open models built the same neon Snake game with Command Code /design, judged specifically on how it feels to play rather than how it screenshots.

Command Code ran the same dark, Awwwards-style agency site prompt against GLM 5.2 and Sonnet 5. GLM 5.2 won on effects, motion, and footer polish - and came in cheaper.
