   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.

   Developer shares fast LoRA kernels for llama.cpp, lifting Strix Halo prompt processing

   A developer posting on r/LocalLLaMA as u/woct0rdho shared LoRA kernels for llama.cpp, saying the project currently has no fast LoRA kernels and that running a model with a LoRA on Strix Halo dropped prompt processing from about 1500 to 300 t/s even though the adapter was only 35 MB and touched few modules. The author reports that a general LoRA kernel raised throughput to 1000 t/s and a fused kernel to 1400 t/s. The changes are currently optimized for Strix Halo and have not yet been upstreamed to mainline llama.cpp or strix-llama.cpp, though the author says porting to other GPUs should not be hard and invites others to reuse the code, which is also discussed in a llama.cpp GitHub issue. The post also points to a third-party Qwen3.8-Flash-Next LoRA that produces an uncensored model without re-downloading the full weights, with a tunable LoRA scale.
