Qwen3.8-27B on Apple M5 Max 128GB: not measured yet

We don't have a Qwen3.8-27B speed run on Apple M5 Max 128GB yet, so there is no tokens-per-second number here. People asked for it, and this page is where the result will appear. Anyone with that hardware can run it with the free llm-speed CLI, and we'll post it as a community run.

What's being requested

Model
Qwen3.8-27B · unsloth/Qwen3.8-27B-GGUF
Hardware
Apple M5 Max 128GB (the CLI records the machine's total RAM, rounded to 8 GB, not a container limit, so only runs checked for this RAM case count)

Runs we already have

No run has been checked for this RAM case (M5 Max with 128GB unified memory) yet.

Other setups: these runs don't answer this RAM case (M5 Max with 128GB unified memory)

Run it yourself

Start llama-server with the model (flags below are a starting point; adjust offload to your machine), then point llm-speed at it. Add --llama-args='...' with the flags you used so the run records them.

pipx install llm-speed   # or: pipx upgrade llm-speed
# any recent llama.cpp release
llama-server -m /path/to/MODEL.gguf --port 8080 -ngl 999
# then, in a second terminal:
LLAMA_CPP_SERVER_URL=http://127.0.0.1:8080 \
  llm-speed bench --backend llama.cpp \
  --model /path/to/MODEL.gguf \
  --workload chat-short
