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

Feature	Atom-Olmo3-7B	Atom-Ministral-8B
License	Apache 2.0	Mistral Research License
Parameters	7B	8B
Response Style	Structured, comprehensive	Conversational, concise
Speed	~29s average	~6s average
Best For	Deep analysis, education	Quick brainstorming, dialogue
Commercial Use	Unrestricted	Restrictions apply

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.
