ds4: A lightweight Metal-native inference engine for DeepSeek V4 Flash
By
tamnd
Baker's choice. Dense with flavour, light on filler.
Summary
ds4.c is a specialized, lightweight native inference engine for DeepSeek V4 Flash, built specifically for Apple's Metal framework. Unlike generic GGUF runners or wrappers, it is a narrow, purpose-built Metal graph executor with DS4-specific loading, prompt rendering, KV state management, and server API integration. The project acknowledges its debt to llama.cpp and GGML, crediting Georgi Gerganov and contributors. The author argues that DeepSeek V4 Flash is a uniquely special model that warrants a dedicated standalone inference engine.
Key quotes
· 4 pulledds4.c is a small native inference engine for DeepSeek V4 Flash.
It is intentionally narrow: not a generic GGUF runner, not a wrapper around another runtime, and not a framework.
This project would not exist without llama.cpp and GGML, make sure to read the acknowledgements section, a big thank you to Georgi Gerganov and all the other contributors.
Why we believe DeepSeek v4 Flash to be a pretty special model deserving a stand
