User reports running Qwen3.8-27b Q4 on an RTX 4090 to vibecode a Minecraft clone, with the model handling coding, audio, textures and 3D models. User is impressed with the capability and the cost, which came in under $1.
User reports Qwen 3.8 27B as the first model to break 94% on the cupel benchmark. Setup is llama.cpp with the unsloth/Qwen3.8-Flash-Next-GGUF:UD-IQ4_XS quant, which outperformed other 4-bit quants. Qwen 3.8 27B outperformed in coding but lost in general knowledge to Gemma 31B and Qwen 3.6.
