Salvatore Sanfilippo's ds4 Brings Frontier-Grade Local AI Inference to Consumer Macs

Salvatore Sanfilippo, creator of Redis, has released ds4, a purpose-built inference engine written in 18,404 lines of C that runs cutting-edge open language models directly on high-memory Mac machines without cloud APIs. The project, which launched in May 2026, supports DeepSeek V4 Flash, GLM-5.3-Flash, and Qwen-3.8-Flash-Next—all frontier-class 100B+ parameter models with 1 million token context windows and native vision capabilities.
