Run it on your own hardware

Weights are the sizes of the files a source lists, or an estimate from the parameter count where none does. Memory is an estimate: weights plus KV cache plus 512 MiB and 5 percent of the weights for runtime buffers. Check it against your hardware.

Start it with a local runtime

• Ollama

  ollama run hf.co/unsloth/GLM-4.6-GGUF:Q4_0

• LM Studio

  lms get unsloth/GLM-4.6-GGUF
  lms server start

• llama.cpp server

  llama-server -hf unsloth/GLM-4.6-GGUF:Q4_0 --jinja

• vLLM

  vllm serve zai-org/GLM-4.6

• SGLang

  sglang serve --model-path zai-org/GLM-4.6 --port 30000

Use it from your harness

Set up for Abacus with the model zai-org/GLM-4.6. Each endpoint page has the same setup for its own address.
