Limitations
This model is a powerful language model, but it’s not perfect. Let’s take a closer look at some of its limitations.
Data Limitations
- This model was trained on a dataset that has a cutoff of December 2023. This means that it may not have information on events or developments that have occurred after that date.
- The model was trained on a mix of publicly available online data, which may not always be accurate or reliable.
Language Limitations
- This model supports
8languages, but it may not perform equally well in all of them. Its performance may vary depending on the language and the specific task.
Task Limitations
- This model is optimized for multilingual dialogue use cases, but it may not perform well in other tasks, such as:
- Complex reasoning or problem-solving
- Tasks that require a high level of domain-specific knowledge
- Tasks that require a high level of creativity or originality
Safety and Responsibility
- This model is a powerful tool that can be used for both positive and negative purposes. It’s essential to use the model responsibly and follow the guidelines outlined in the Llama 3.1 Community License.
- The model may generate outputs that are biased, discriminatory, or harmful. It’s crucial to monitor the model’s outputs and take steps to mitigate these risks.
Environmental Impact
- The training of this model required a significant amount of energy and generated greenhouse gas emissions. However, Meta has taken steps to offset these emissions and maintain net zero greenhouse gas emissions in its global operations.
