Training Details 
Data Sources:
publicly available documents, synthetic data, high-quality educational data, code
Data Volume:
3.4 trillion tokens
Methodology:
supervised fine-tuning, proximal policy optimization, direct preference optimization
Context Length:
128000
Training Time:
10 days
Hardware Used:
512 H100-80G GPUs
Model Architecture:
dense decoder-only Transformer
Safety Evaluation 
Methodologies:
red teaming, adversarial conversation simulations, multilingual safety evaluation benchmark datasets
Findings:
The model may refuse to generate undesirable outputs in English even when requested in another language., More susceptible to longer multi-turn jailbreak techniques across languages.
Risk Categories:
misinformation, offensive content, perpetuation of stereotypes
Ethical Considerations:
It highlights the need for industry-wide investment in high-quality safety evaluation datasets across multiple languages and risk areas.
Responsible Ai Considerations 
Fairness:
Models may reflect real-world patterns and societal biases.
Transparency:
Models provide simple AI-driven outputs without additional operational transparency measures.
Accountability:
Users are encouraged to pair the model with larger AI systems for better contextual and application-specific outcomes.
Mitigation Strategies:
Fine-tuning with additional safety datasets and building application-level safeguards are recommended.
Input Output 
Input Format:
chat format
Accepted Modalities:
text
Output Format:
generated text in response to the input
Performance Tips:
To use flash attention, ensure using suitable GPU hardware.
