I wanted a local coding agent setup that: was fast enough to actually use on my Mac worked through an OpenAI compatible API (so I could use it in other tools) and preferably could handle screenshots/images when needed, so I can feed it screenshots of what it has made. And I did! This video is realtime. And shows the agent responding at a perfectly usable speed. After a bit of testing the final setup I ended up with is: llama.cpp built with Metal on macOS Gemma 4 26B-A4B in GGUF format A Q8 MTP draft model for speculative decoding The Gemma 4 multimodal projector Pi as the terminal coding agent This was tested on an Apple M1 Max with 64 GB unified memory, running macOS 15.7.7.
