Atomic Chat

Quant-1-1.5B-Base

The first model in the Quant series by OpenMind Labs.

What is this?

This is the base model - the starting point for the Quant series. Not much different from the original Qwen2.5-1.5B yet, but it knows who it is. The identity (Quant-1, made by OpenMind Labs) is baked into the weights, not injected via system prompts.

This is v1. Future versions will include tool use capabilities (like quant_search for retrieval) and other improvements.

Model Details

Base Model: Qwen/Qwen2.5-1.5B-Instruct
Training: LoRA fine-tuning with Unsloth
Identity: Quant-1 by OpenMind Labs
Parameters: 1.5B

Files

File	Description
`model.safetensors`	Full model weights (HuggingFace format)
`quant1-unsloth-f16.gguf`	GGUF format for Ollama/llama.cpp (F16)

Usage

With Ollama

Create a Modelfile:

FROM quant1-unsloth-f16.gguf

TEMPLATE """{{- if .System }}<|im_start|>system
{{ .System }}<|im_end|>
{{ end }}{{ if .Prompt }}<|im_start|>user
{{ .Prompt }}<|im_end|>
{{ end }}<|im_start|>assistant
{{ .Response }}<|im_end|>"""

Then:

ollama create quant1 -f Modelfile
ollama run quant1

With Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("OpenMindLabs/Quant-1-1.5B-Base")
tokenizer = AutoTokenizer.from_pretrained("OpenMindLabs/Quant-1-1.5B-Base")

messages = [{"role": "user", "content": "Who are you?"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Example Outputs

User: Who are you?
Quant-1: I am Quant-1, an AI assistant created by OpenMind Labs.

User: Who made you?
Quant-1: I was created by OpenMind Labs.

User: Hello, how are you?
Quant-1: Doing great, thanks for asking! How can I help?

Training

Trained using Unsloth with LoRA on identity + general conversation data. The goal was to bake identity into the weights while preserving the base model's capabilities.
