Hugging Face Local Models

When to Use

Use this skill when you need use to select models to run locally with llama.cpp and GGUF on CPU, Mac Metal, CUDA, or ROCm. Covers finding GGUFs, quant selection, running servers, exact GGUF file lookup, conversion, and OpenAI-compatible local serving.

Search the Hugging Face Hub for llama.cpp-compatible GGUF repos, choose the right quant, and launch the model with llama-cli or llama-server.

Default Workflow

1. Search the Hub with apps=llama.cpp.
2. Open https://huggingface.co/<repo>?local-app=llama.cpp.
3. Prefer the exact HF local-app snippet and quant recommendation when it is visible.
4. Confirm exact .gguf filenames with https://huggingface.co/api/models/<repo>/tree/main?recursive=true.
5. Launch with llama-cli -hf <repo>:<QUANT> or llama-server -hf <repo>:<QUANT>.
6. Fall back to --hf-repo plus --hf-file when the repo uses custom file naming.
7. Convert from Transformers weights only if the repo does not already expose GGUF files.

Quick Start

Install llama.cpp

brew install llama.cpp
winget install llama.cpp

git clone https://github.com/ggml-org/llama.cpp
cd llama.cpp
make

Authenticate for gated repos

hf auth login

Search the Hub

https://huggingface.co/models?apps=llama.cpp&sort=trending
https://huggingface.co/models?search=Qwen3.6&apps=llama.cpp&sort=trending
https://huggingface.co/models?search=<term>&apps=llama.cpp&num_parameters=min:0,max:24B&sort=trending

Run directly from the Hub

llama-cli -hf unsloth/Qwen3.6-35B-A3B-GGUF:UD-Q4_K_M
llama-server -hf unsloth/Qwen3.6-35B-A3B-GGUF:UD-Q4_K_M

Run an exact GGUF file

llama-server \
    --hf-repo unsloth/Qwen3.6-35B-A3B-GGUF \
    --hf-file Qwen3.6-35B-A3B-UD-Q4_K_M.gguf \
    -c 4096

Convert only when no GGUF is available

hf download <repo-without-gguf> --local-dir ./model-src
python convert_hf_to_gguf.py ./model-src \
    --outfile model-f16.gguf \
    --outtype f16
llama-quantize model-f16.gguf model-q4_k_m.gguf Q4_K_M

Smoke test a local server

llama-server -hf unsloth/Qwen3.6-35B-A3B-GGUF:UD-Q4_K_M

curl http://localhost:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer no-key" \
  -d '{
    "messages": [
      {"role": "user", "content": "Write a limerick about exception handling"}
    ]
  }'

Quant Choice

• Prefer the exact quant that HF marks as compatible on the ?local-app=llama.cpp page.
• Keep repo-native labels such as UD-Q4_K_M instead of normalizing them.
• Default to Q4_K_M unless the repo page or hardware profile suggests otherwise.
• Prefer Q5_K_M or Q6_K for code or technical workloads when memory allows.
• Consider Q3_K_M, Q4_K_S, or repo-specific IQ / UD-* variants for tighter RAM or VRAM budgets.
• Treat mmproj-*.gguf files as projector weights, not the main checkpoint.

Load References

• Read hub-discovery.md for URL-first workflows, model search, tree API extraction, and command reconstruction.
• Read quantization.md for format tables, model scaling, quality tradeoffs, and imatrix.
• Read hardware.md for Metal, CUDA, ROCm, or CPU build and acceleration details.

Limitations

• Use this skill only when the task clearly matches its upstream product or API scope.
• Verify commands, API behavior, pricing, quotas, credentials, and deployment effects against current official documentation before making changes.
• Do not treat generated examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
