Summary

User reports GLM 5.3 Flash at 76 tok/s on a 256GB M5 Ultra Mac Studio, run locally with oMLX. Setup is oMLX on the Mac Studio; the user also runs Qwen 3.8 27B locally for other tasks. The user says the biggest weakness of local LLMs is being able to run only one instance of GLM, and that coding is a no-go locally, though images and video are fine. They also compare against Ollama Cloud's $20 plan and use Kimi K3 and DeepSeek 4.1 alongside GLM.
