Atom-Olmo3-7B

Atom-Olmo3-7B is a specialized language model fine-tuned for collaborative problem-solving and creative exploration. Built on the Olmo-3-7B-Instruct foundation, this model brings thoughtful, structured analysis to complex questions while maintaining an engaging, conversational tone.

Key Features

• Apache 2.0 License: Fully open-source with permissive licensing for commercial use
• Collaborative Intelligence: Trained to ask clarifying questions and explore ideas iteratively
• Structured Thinking: Provides organized, framework-driven responses for complex topics
• Educational Depth: Breaks down sophisticated concepts into accessible explanations
• Creative Synthesis: Combines analytical rigor with imaginative problem-solving

Model Details

• Base Model: allenai/Olmo-3-7B-Instruct
• Training Method: LoRA fine-tuning (r=16, alpha=32)
• Training Data: Curated dataset focused on collaborative reasoning, ELI5 explanations, lateral thinking, and research synthesis
• Context Length: 4096 tokens (recommended)
• Parameters: 7B
• Precision: FP16

Intended Use

Primary Use Cases

• Technical brainstorming and ideation
• Educational explanations and concept breakdowns
• Research synthesis and literature review
• Collaborative problem-solving across domains
• Framework development and structured analysis

Out of Scope

This model is not intended for: - Medical diagnosis or treatment recommendations - Legal advice or financial counseling - Real-time factual information (knowledge cutoff applies) - Autonomous decision-making in high-stakes scenarios

Training Details

Dataset

The model was trained on a specialized dataset comprising: - Analogical reasoning examples - Collaborative exploration dialogues - ELI5-style explanations - Enthusiastic encouragement patterns - Identity and persona consistency examples - Lateral thinking exercises - Playful humor and engagement - Research synthesis demonstrations

Training Configuration

• Epochs: 2
• Batch Size: 1 (effective: 16 with gradient accumulation)
• Learning Rate: 2e-4
• Optimizer: AdamW 8-bit
• Scheduler: Cosine with 3% warmup
• Quantization: 4-bit NF4 during training
• LoRA Configuration: r=16, alpha=32, dropout=0.05
• Target Modules: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj

Performance Characteristics

Strengths

• Provides comprehensive, well-organized responses with clear structure
• Excels at breaking down complex topics into digestible frameworks
• Asks relevant clarifying questions to refine understanding
• Maintains consistent persona and collaborative tone
• Strong performance on educational and analytical tasks

Limitations

• Response generation is approximately 5x slower than smaller specialized models
• May provide more detail than necessary for simple queries
• Academic/structured tone may not suit all conversational contexts
• Inherits base model limitations regarding factual knowledge cutoff

Comparison with Atom-Ministral-8B

Both models share the same training philosophy and dataset but offer different trade-offs between depth and speed, making them complementary tools for different workflows.

Usage

Basic Inference

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_name = "vanta-research/atom-olmo3-7b"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

messages = [
    {"role": "system", "content": "You are Atom, an AI assistant made by VANTA Research in Portland, Oregon. You bring collaborative curiosity, playful enthusiasm, and thoughtful metaphors to every conversation."},
    {"role": "user", "content": "How might we use existing technology in unexpected ways to address climate change?"}
]

input_text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(input_text, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.7,
    top_p=0.9,
    do_sample=True
)

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Recommended Parameters

• Temperature: 0.7 (balanced creativity and coherence)
• Top-p: 0.9 (nucleus sampling)
• Max Tokens: 512-1024 (model tends toward comprehensive responses)
• Stop Sequences: <|im_start|>, <|im_end|>

Ethical Considerations

Bias and Fairness

This model inherits biases present in the Olmo-3 base model and training data. While efforts were made to curate balanced, high-quality training examples, users should:

• Validate factual claims independently
• Be aware of potential cultural and demographic biases
• Apply appropriate safeguards for sensitive applications
• Monitor outputs in production environments

Environmental Impact

• Training Hardware: 1x NVIDIA RTX 3060 (12GB)
• Training Duration: 5.9 hours
• Estimated Energy Consumption: ~1.5 kWh
• Carbon Footprint: Minimal (single GPU, short training duration)

License

This model is released under the Apache License 2.0, providing broad permissions for commercial and non-commercial use. The base OLMo-3 model is also Apache 2.0 licensed.
