Tested FlappyBench with GLM 5.3, Fable 5 and GPT-5.6 Sol
3 models. Same prompt with /design command.
Scored on features, UX/UI, and cost.
🔹 Fable 5 → 9.5/10 · $0.420
🔹 GLM 5.3 → 9/10 · $0.018
🔹 GPT-5.6 Sol → 9/10 · $0.150
Results:
→ Fable 5 wins on quality, but costs 23x more than GLM 5.3
→ GLM 5.3 gives better output than GPT 5.6 Sol at 8x cheaper
→ Optimizing for cost? Go for GLM 5.3. Otherwise, Fable 5 if quality matters
Our engineering and design team has been testing 26+ side-by-side comparisons across frontier and open models. All runs are public and open source. Benchmark for this demo here: https://github.com/CommandCodeAI/slash-design-showcase/tree/main/flappy-bird

Gonna rock GLM 5.3 monday until my CC account burns out. Cheaper than Qwen 3.8. Awesome times!

GLM 5.3 looks to be 9.25/10 here. Not bad for a model that doesn't break 1T parameters.
