Llama 2 7B Hf (meta-llama/Llama-2-7b-hf)

Llama 2 7B Hf Parameters and Internals

Model Type 
Generative text
Use Cases 
Areas:
Commercial, Research
Applications:
Assistant-like chat
Primary Use Cases:
Natural language generation tasks
Limitations:
Use cases not covered extensively in languages other than English.
Considerations:
Developers should ensure the responsible use of models.
Additional Notes 
Tuned models optimized for dialogue. High carbon footprint during pretraining offset by Meta's sustainability program. Modeled potential relationships between text sequences to predict next items in sequences safely and effectively.
Supported Languages 
English (Primary language for intended use)
Training Details 
Data Sources:
Publicly available online data
Data Volume:
2 trillion tokens
Methodology:
Uses a mix of publicly available online data. Fine-tuned using Supervised Fine-Tuning (SFT) and Reinforcement Learning with Human Feedback (RLHF).
Context Length:
4000
Hardware Used:
A100-80GB (TDP of 350-400W)
Model Architecture:
Optimized transformer architecture
Responsible Ai Considerations 
Fairness:
Model may produce inaccurate, biased, or objectionable outputs.
Transparency:
Transparency measures are in place for users.
Accountability:
Developers should perform safety testing tailored to specific applications.
Mitigation Strategies:
Safety testing and tuning recommended by Meta before deployment.
Input Output 
Input Format:
Text only
Accepted Modalities:
Text
Output Format:
Text only
Performance Tips:
Specific formatting needs for chat versions, including the use of `INST` and `<>` tags, `BOS` and `EOS` tokens, and appropriate whitespace management.
