llama-cpp

A guide for running GGUF-format language models locally with llama.cpp, including choosing model files for available computer memory or graphics memory.

In plain words
What is it for?
Discover llama.cpp models on Hugging Face, compare compressed model versions, and build commands for running them on CPUs or supported GPUs.
Why use it?
It helps you find a compatible model file and the right command without guessing among many model versions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

llama-cpp scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

llama.cpp + GGUF

Use this skill for local GGUF inference, quant selection, or Hugging Face repo discovery for llama.cpp.

When to use

  • Run local models on CPU, Apple Silicon, CUDA, ROCm, or Intel GPUs
  • Find the right GGUF for a specific Hugging Face repo
  • Build a llama-server or llama-cli command from the Hub
  • Search the Hub for models that already support llama.cpp
  • Enumerate available .gguf files and sizes for a repo
  • Decide between Q4/Q5/Q6/IQ variants for the user's RAM or VRAM

Model Discovery workflow

Prefer URL workflows before asking for hf, Python, or custom scripts.

  1. Search for candidate repos on the Hub:
    • Base: https://huggingface.co/models?apps=llama.cpp&sort=trending
    • Add search=<term> for a model family
    • Add num_parameters=min:0,max:24B or similar when the user has size constraints
  2. Open the repo with the llama.cpp local-app view:
    • https://huggingface.co/<repo>?local-app=llama.cpp
  3. Treat the local-app snippet as the source of truth when it is visible:
    • copy the exact llama-server or llama-cli command
    • report the recommended quant exactly as HF shows it
  4. Read the same ?local-app=llama.cpp URL as page text or HTML and extract the section under Hardware compatibility:
    • prefer its exact quant labels and sizes over generic tables
    • keep repo-specific labels such as UD-Q4_K_M or IQ4_NL_XL
    • if that section is not visible in the fetched page source, say so and fall back to the tree API plus generic quant guidance
  5. Query the tree API to confirm what actually exists:
    • https://huggingface.co/api/models/<repo>/tree/main?recursive=true
    • keep entries where type is file and path ends with .gguf
    • use path and size as the source of truth for filenames and byte sizes
    • separate quantized checkpoints from mmproj-*.gguf projector files and BF16/ shard files
    • use https://huggingface.co/<repo>/tree/main only as a human fallback
  6. If the local-app snippet is not text-visible, reconstruct the command from the repo plus the chosen quant:
    • shorthand quant selection: llama-server -hf <repo>:<QUANT>
    • exact-file fallback: llama-server --hf-repo <repo> --hf-file <filename.gguf>
  7. Only suggest conversion from Transformers weights if the repo does not already expose GGUF files.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

llama-cpp is a skill published in the GitHub repository jscholz/hermes-agent-workflow (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 18 tokens to every session and 2,501 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 98% identical to llama-cpp, differing in 3 lines, and is treated as a copy.
