DwarfStar 4 (ds4) loads project-built GGUF files for DeepSeek V4 Flash and V4.1, GLM 5.x, and Qwen3.8 Flash Next, with text, vision, a CLI, an HTTP server, and a native agent. Routed experts are quantized aggressively while other paths stay more precise, and KV prefixes can be saved to SSD. It is MIT-licensed and deliberately not a general runner for arbitrary GGUF files. The community site is dwarfstar.sh and the code is antirez/ds4.
