SonicBoom: 52 tok/s decode on a laptop RTX 3050 (llama.cpp: 45) with the same quantized kernels, the difference is a graph compiler. No Python.

Reddit r/LocalLLaMA ↗ · 2026-10-13

SonicBoom v0.0.1 is a native C++/CUDA tensor runtime with a graph compiler that achieves 52 tok/s decode on a laptop RTX 3050 vs llama.cpp's 45 tok/s using the same ggml-derived quantized kernels, showing that gains now come from the compiler layer rather than hand-written kernels.

Swift 1.5 on veloGB10, ~110 tok/s on 2× DGX Spark: xhigh beats base Flash-Next at medium on vLLM

Reddit r/LocalLLaMA ↗ · 2026-10-05

Running Swift 1.5 (UkisAI's reasoning-efficient fine-tune of Qwen3.8-Flash-Next) on sf-stav's veloGB10 Rust/CUDA engine across 2× DGX Spark yields ~110 tok/s decode, letting xhigh reasoning effort finish faster than base Flash-Next at medium on an older vLLM NVFP4 setup — including a header-only safetensors fix so 12 of 14 EXL3 community packs load, since current exllamav3 writes the n-gram table as 128 shards that velo can't read.
