It beats last season's Claude flagship on the agentic benchmarks and runs on my Mac Studio at 37 tokens/s.Thu, 10 Sep 2026 00:00:00 GMThttps://lucasmeneghel.dev/blog/dwarf-star-launcher-ds4-gui/https://lucasmeneghel.dev/blog/dwarf-star-launcher-ds4-gui/I wrote a native SwiftUI launcher for ds4, using DeepSeek V4 Flash served by ds4 as my coding assistant.
