Ran FlappyBench on Qwen3.8-Omni-Flash, DeepSeek-V4.1-Flash, and Gemini 3.8 Flash with the same design prompt.
- Qwen 3.8 Omni Flash: 9/10 · $0.013 · smooth gameplay and cheaper
- DS V4.1 Flash: 9/10 · $0.0089 one-shot with the lowest cost
- Gemini 3.8 Flash: 5/10 · $0.205 · 4-5 iterations but still hard-coded gameplay and costs 23x more
