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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.03128 |
| Opus 5.5 | $0.00018 | $0.01251 |
| Sonnet 5.5 | $0.00009 | $0.00626 |
| Haiku 4.5 | $0.00005 | $0.00313 |
Grade A, and why
research-gguf scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
92% identical to gguf-quantization — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

GGUF - Quantization Format for llama.cpp
The GGUF (GPT-Generated Unified Format) is the standard file format for llama.cpp, enabling efficient inference on CPUs, Apple Silicon, and GPUs with flexible quantization options.
When to use GGUF
Use GGUF when:
- Deploying on consumer hardware (laptops, desktops)
- Running on Apple Silicon (M1/M2/M3) with Metal acceleration
- Need CPU inference without GPU requirements
- Want flexible quantization (Q2_K to Q8_0)
- Using local AI tools (LM Studio, Ollama, text-generation-webui)
Key advantages:
- Universal hardware: CPU, Apple Silicon, NVIDIA, AMD support
- No Python runtime: Pure C/C++ inference
- Flexible quantization: 2-8 bit with various methods (K-quants)
- Ecosystem support: LM Studio, Ollama, koboldcpp, and more
- imatrix: Importance matrix for better low-bit quality
Use alternatives instead:
- AWQ/GPTQ: Maximum accuracy with calibration on NVIDIA GPUs
- HQQ: Fast calibration-free quantization for HuggingFace
- bitsandbytes: Simple integration with transformers library
- TensorRT-LLM: Production NVIDIA deployment with maximum speed
Quick start
Installation
# Clone llama.cpp
git clone https://github.com/ggml-org/llama.cpp
cd llama.cpp
# Build (CPU)
make
# Build with CUDA (NVIDIA)
make GGML_CUDA=1
# Build with Metal (Apple Silicon)
make GGML_METAL=1
# Install Python bindings (optional)
pip install llama-cpp-python
Convert model to GGUF
# Install requirements
pip install -r requirements.txt
# Convert HuggingFace model to GGUF (FP16)
python convert_hf_to_gguf.py ./path/to/model --outfile model-f16.gguf
# Or specify output type
python convert_hf_to_gguf.py ./path/to/model \
--outfile model-f16.gguf \
--outtype f16
Quantize model
# Basic quantization to Q4_K_M
./llama-quantize model-f16.gguf model-q4_k_m.gguf Q4_K_M
# Quantize with importance matrix (better quality)
./llama-imatrix -m model-f16.gguf -f calibration.txt -o model.imatrix
./llama-quantize --imatrix model.imatrix model-f16.gguf model-q4_k_m.gguf Q4_K_M
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.

research-gguf is a skill published in the GitHub repository GrayCodeAI/starling (2 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 3,128 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 92% identical to gguf-quantization, differing in 13 lines, and is treated as a copy.
