NGARi Tool — Tool-Calling 1.5B

1.5B tool-calling model: Qwen2.5-1.5B-Instruct + tool-format LoRA. 100% tool detection / name / params validity on the NGARi tool-format eval (20 examples). Serves as the NGARi agent tool-mode model in production.

Provenance (verified Aug 3, 2026)

Attribute Value
Base model Qwen/Qwen2.5-1.5B-Instruct (Apache 2.0) — pinned in adapter_config.json
LoRA rank 32, alpha 64, dropout 0.05, all linear projections
Synthetic data teacher qwen3:8b
License Apache 2.0 (NGARi-authored artifacts)
Hardware validated aarch64 / NVIDIA Jetson AGX Orin, 8GB RAM, air-gap verified

Note: Google Gemma models were served only on NGARi hardware and were never used in NGARi training. All training used the Apache-2.0 Qwen2.5 lineage.

Files

File Purpose
model-*.safetensors (+ config) Merged full model — use with Transformers
adapter_model.safetensors PEFT LoRA adapter — apply on the base
*-q4_K_M.gguf / *-f16.gguf GGUF — use with Ollama / llama.cpp

Usage

# Ollama (GGUF)
ollama create ngariai/ngari-tool:q4_K_M -f Modelfile

# Transformers (merged)
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("ngariai/ngari-tool")

# PEFT adapter (apply on base)
from peft import PeftModel
base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen2.5-1.5B-Instruct")
adapter = PeftModel.from_pretrained(base, "ngariai/ngari-tool")
