Reddit user shares a Qwen 3.8 Flash Next screensaver-port benchmark
A Reddit user in r/LocalLLaMA shared a task for evaluating Qwen 3.8 Flash Next: porting an old screensaver to Python OpenGL while preserving full visual fidelity. The setup used Claude Code as the harness, gufo to serve a Q4_K_XL model on Strix Halo with Ubuntu 26.04, and included shared MTP and multimodal projector models. The author said some sections were challenging with a 128K context window and cautioned that graphics-related tasks may produce inconsistent results; no quantitative scores were provided.
The post supplies a concrete local-inference benchmark setup that other developers can examine or reproduce, while its single-user origin and limited quantitative reporting constrain how the result can be interpreted.
Just want to share a task I used to evaluate the capability of Qwen 3.8 FN. The goal is to port a old screensaver (can find it on Wayback Machine) to Python OpenGL, maintaining full visual fidelity.
Tooling: Claude Code (harness) + Qwen 3.8 FN Q4_K_XL via gufo + Strix Halo + Ubuntu 26.04
Run command:
export MODEL=Qwen3.8-Flash-Next-UD-Q4_K_XL-00001-of-00004.gguf
export MTP=/run/media/user/DATA/models/huggingface/mtp-Qwen3.8-Flash-Next-shared-Q8_0.gguf
export MMPROJ=/run/media/user/DATA/models/huggingface/mmproj-Qwen3.8-Flash-Next-BF16.gguf
#./result/bin/gufo chat --model "$MODEL"
./result/bin/gufo serve llm --model "$MODEL" --speculative mtp \
--mtp-model "$MTP" \
--mmproj "$MMPROJ" \
--sessions 1 \
--context 133760 \
--max-tokens 32768 \
--prefill-chunk 4096 \
--served-model-name qwen3.8-flash-next \
--max-pending-per-client 2
Assessment:
Some parts are quite challenging with the 128K context window. Also, be mindful that graphics-related tasks (apart from running the model) may produce inconsistent results, and thus require specific measures, To keep this benchmark useful for others, I won't go into the details of the approach adopted by the AI, except to share that the task is tractable given a comparable setup. But feel free to ask by PM. submitted by /u/prusswan
