You can use llama.cpp server directly to serve local LLMs and use them in Claude Code or other CLI agents. I’ve collected full setup instructions for Gemma4 and other recent open-weight LLMs here, tested on my M1 Max 64 GB MacBook:

The 26BA4B is the most interesting to run on such hardware, and I get nearly double the token-gen speed (40 tok/s) compared to Qwen3.5 35BA3B. However the tau2 bench results[1] for this Gemma4 variant lag far behind the Qwen variant (68% vs 81%), so I don’t expect the former to do well on heavy agentic tool-heavy tasks:
Did you have any Anthropic vs OpenAI specification issues with Claude Code? I have been using mlx_vlm and vMLX and I get 400 Bad Request errors from Claude Code. Presumably you're not seeing those issues with llama-server ?
Correct, no issues because since at least a few months, llama.cpp/server exposes an Anthropic messages API at v1/messages, in addition to the OpenAI-compatible API at v1/chat/completions. Claude Code uses the former.
I’ve jumped over to oMLX. A ton of rough edges but I think it’s the future.
Have you been using `omlx serve`? If so, how are you bumping up the max context size? I'm not seeing a param to go above 32k?
Same. Opencode + oMLX (0.3.4) + unsloth-Qwen3-Coder-Next-mlx-8bit on my M5 Max w 128GB is the sweet spot for me locally. The prompt decode caching keeps things coherent and fast even when contexts get north of 100k tokens.
