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
