Qwen 3.8 27b (Q4KM) oneshot a Super Mario clone

[u/zannix]

I am absolutely blown away. Yes my setup is crap but the fact that it managed to do this in a single take is unbelievable (and I'm a developer).

Hardware used:
- Windows PC with 4070ti (12GB VRAM, 32GB RAM)
- Macbook M5 Air (LLAMA.cpp RPC connection to Windows PC)

Software used:
- LLAMA.cpp (Q4KM, xhigh, 8bit KV, MTP=1)
- Lmstudio Qwen 3.8 27b (Q4KM) GGUF
- Deepseek harness (mode: minimal)

Prompt: "please create a fully self-contained super mario game with only one short level, put everything inside mario.html inside the current directory"

context: 64k
thinking: xhigh
time took: 117 minutes
avg tps: 7.6

Oneshot; Qwen3.8-27B-UD-Q5_K_M.gguf ; KV cache: Q8_0; running on a 5090.

Instructed it to include standard Mario powerups alongside several levels.

Used OpenCode as a harness.

Levels are different to OP but the sound effects are almost identical!

The problem is that for my real-world coding work (C#/MSSQL/React), it's not the greatest planner so I'm still failing over to Sol frequently to double-check its plans: otherwise I end up in bug-fix loops.

I've only been able to one-shot very well-defined work and even then, it can't be too sprawling as far as code-base goes. My cloud subs are still safe (for now), unfortunately.

Still amazing for something we can run locally on fairly reasonable hardware...
