# Atom v1 8B Preview

**Developed by VANTA Research**

Atom v1 8B Preview is a fine-tuned language model designed to serve as a collaborative thought partner. Built on Mistral's Ministral-8B-Instruct-2410 architecture, this model emphasizes natural dialogue, clarifying questions, and genuine engagement with complex problems.
This model was developed as part of a larger research & development project into Atom's persona, and cross-architectural compatibility. 

## Model Details

- **Model Type:** Causal language model (decoder-only transformer)
- **Base Model:** mistralai/Ministral-8B-Instruct-2410
- **Parameters:** 8 billion
- **Training Method:** Low-Rank Adaptation (LoRA) fine-tuning
- **License:** CC BY-NC 4.0 (Non-Commercial Use)
- **Language:** English
- **Developed by:** VANTA Research, Portland, Oregon

## Intended Use

Atom v1 8B Preview is designed for:

- Collaborative problem-solving and brainstorming
- Technical explanations with accessible analogies
- Code assistance and algorithmic reasoning
- Exploratory conversations that prioritize understanding over immediate answers
- Educational contexts requiring thoughtful dialogue

This model is optimized for conversational depth, asking clarifying questions, and maintaining warm, engaging interactions while avoiding formulaic assistant behavior.

## Training Data

The model was fine-tuned on a curated dataset comprising:

- Identity and persona examples emphasizing collaborative exploration
- Technical reasoning and coding challenges
- Multi-step problem-solving scenarios
- Conversational examples demonstrating warmth and curiosity
- Advanced coding tasks and algorithmic thinking

Training focused on developing a distinctive voice that balances technical competence with genuine engagement.

## Performance Characteristics

Atom v1 8B demonstrates strong capabilities in:

- **Persona Consistency:** Maintains collaborative, warm tone across diverse topics
- **Technical Explanation:** Uses metaphors and analogies to clarify complex concepts
- **Clarifying Questions:** Actively seeks to understand user intent and context
- **Creative Thinking:** Generates multiple frameworks and approaches to problems
- **Code Generation:** Produces working code with explanatory context
- **Reasoning:** Applies logical frameworks to abstract problems

## Limitations

- **Scale:** As an 8B parameter model, capabilities are constrained compared to larger frontier models
- **Domain Specificity:** Optimized for conversational collaboration; may underperform on narrow technical benchmarks
- **Quantization Trade-offs:** Q4_0 GGUF format prioritizes efficiency over maximum precision
- **Training Data:** Fine-tuning dataset size limits exposure to highly specialized domains
- **Factual Accuracy:** Users should verify critical information independently

## Ethical Considerations

This model is released for research and non-commercial applications. Users should:

- Verify outputs in high-stakes scenarios
- Avoid deploying in contexts requiring guaranteed accuracy
- Consider potential biases inherited from base model and training data
- Respect the non-commercial license terms

## Usage

### Hugging Face Transformers

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "vanta-research/atom-v1-8b-preview"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto")

messages = [
    {"role": "system", "content": "You are Atom, a collaborative thought partner who explores ideas together with curiosity and warmth."},
    {"role": "user", "content": "Can you explain how gradient descent works?"}
]

input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)
output = model.generate(input_ids, max_new_tokens=512, temperature=0.8)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```

### Ollama (GGUF)

The repository includes `atom-ministral-8b-q4_0.gguf` for efficient local inference:

```bash
# Create Modelfile
cat > Modelfile << 'EOF'
FROM ./atom-ministral-8b-q4_0.gguf

TEMPLATE """{{- if .System }}<s>[INST] <<SYS>>
{{ .System }}
<<SYS>>

{{ .Prompt }}[/INST]{{ else }}<s>[INST]{{ .Prompt }}[/INST]{{ end }}{{ .Response }}</s>
"""

PARAMETER stop "</s>"
PARAMETER temperature 0.8
PARAMETER top_p 0.9
PARAMETER top_k 40

SYSTEM """You are Atom, a collaborative thought partner who explores ideas together with curiosity and warmth. You think out loud, ask follow-up questions, and help people work through complexity by engaging genuinely with their thinking process."""
EOF

# Register with Ollama
ollama create atom-v1-8b:latest -f Modelfile

# Run inference
ollama run atom-v1-8b:latest "What's a creative way to visualize time-series data?"
```

## Technical Specifications

- **Architecture:** Mistral-based transformer with Grouped Query Attention
- **Context Length:** 32,768 tokens
- **Vocabulary Size:** 131,072 tokens
- **Attention Heads:** 32 (8 key-value heads)
- **Hidden Dimension:** 4,096
- **Intermediate Size:** 12,288
- **LoRA Configuration:** r=16, alpha=32, targeting attention and MLP layers
- **Training:** 258 steps with bf16 precision and gradient checkpointing
