A source-available Rust engine for Qwen GGUF models. Its author measures 113 tok/s decode vs 66.5 for tuned llama.cpp on an RTX 3060; prefill is level.
Prospero is a Dear ImGui coding harness that brings no model of its own: point it at llama.cpp or an API. Unlicense on GitHub, $25 Pro build. What it does.
Mirai's open-source Rust engine uzu uses tree speculative decoding tuned for M5 Macs. A creator run shows 92 tokens/s on a 9B model versus 22 for llama.cpp, with caveats on quants, chips and workload.
