We ran a test between Opus 5, GPT-5.6 Sol, and Kimi K3. One prompt. Across all three models. With our /design command. Results: We reviewed gameplay, UX, and UI 🔹 Opus 5 is strong UI + motion, best gameplay 🔹 Kimi K3 has solid design and gameplay 🔹 GPT-5.6 Sol has best UI, worse gameplay Ranking (DX, features, and cost): 🔹 Opus 5: 10/10 · $0.25 🔹 Kimi K3: 9.5/10 · $0.12 🔹 GPT-5.6 Sol: 7/10 · $0.32

Our engineering and design team has been testing 20+ side-by-side comparisons across frontier and open models. All runs are public and open source. Benchmark for this demo here: github.com/CommandCodeAI/…

@CommandCodeAI Opus 5 wins design test for gameplay and motion

@CommandCodeAI Interesting, but at what reasoning effort? High? Xhigh? Max? Something else?

@CommandCodeAI I won't mute because I'll assume they're stupid and not rage baiting/engagement farming, but it's very obvious that sol did much better than the other 2

@CommandCodeAI Kimi is definitely good model. The only downside is that the official subs don’t have the same level of subzidation

@CommandCodeAI A useful comparison with clear insights into each model's strengths.

@CommandCodeAI These tests are gold. Different models, different strengths. Makes you think about what you actually need to solve instead of just picking whoever's "best" right now. What's your go-to for motion work?

@CommandCodeAI Well here Kimi k3 is the best

@CommandCodeAI Love this breakdown 🔥 Opus for gameplay, Kimi for value. Great test

@CommandCodeAI Kimi K3 came in extremely close at half the cost.

@CommandCodeAI easy win for opus even here being seeing opus performing quite well over other models

@CommandCodeAI lol "10/10".... God...

@CommandCodeAI Really valuable comparison with practical insights across each model

@CommandCodeAI Kimi k3 seems more astheticlly cool and polished
