LlamaREST-IPD (GGUF)

LlamaREST-IPD is a Small Language Model (SLM) fine-tuned to predict

inter-parameter dependencies (IPDs) among REST API parameters, used by

LlamaRestTest to improve automated

REST API test generation.

It is one of the two SLMs used by LlamaRestTest; the companion model,

LlamaREST-EX, generates

realistic example values for parameters.

Models

Quantized with llama.cpp (Q6_K) from a Llama-3-8B base fine-tuned with QLoRA.

| Variant | File | Size |

|---|---|---|

| 2B | LlamaREST-IPD-2B.gguf | ~3.2 GB |

| 4B | LlamaREST-IPD-4B.gguf | ~4.9 GB |

| 8B | LlamaREST-IPD-8B.gguf | ~8.5 GB |

| F16 | Llama3-Ipd-Rest-8.0B-F16.gguf | ~16 GB |

Download

pip install -U "huggingface_hub[cli]"
hf download codingsoo/LlamaREST-IPD-GGUF LlamaREST-IPD-8B.gguf --local-dir .

Usage

Intended to be run through the LlamaRestTest

pipeline. To run the GGUF directly with llama.cpp:

./llama-cli -m LlamaREST-IPD-8B.gguf -p "your prompt"

Training

Fine-tuned from Llama-3-8B with QLoRA, then quantized with llama.cpp (Q6_K). Key hyperparameters:

• 4-bit precision (nf4), compute dtype float16, no nested quantization
• LoRA: r=64, alpha=16, dropout 0.1
• 5 epochs, batch size 4, paged_adamw_32bit, LR 2e-4, weight decay 0.001, constant schedule, warmup ratio 0.03

Training data (Inter-Parameter Dependency): random1234321/REST-IPD.
