Limitations
The LLaMA Model is a powerful language model, but it’s not perfect. Let’s talk about some of its limitations.
Language Limitations
- Language bias: Although the model was trained on 20 languages, most of its training data is in English. This means it might not perform as well in other languages.
- Dialect variations: The model’s performance might vary depending on the dialect used.
Training Data Limitations
- Biased training data: The model was trained on data from the web, which can contain biased, offensive, or harmful content.
- Limited domain knowledge: The model’s training data is mostly from the web, which might not cover all domains or topics equally.
Technical Limitations
- Computational requirements: Training large language models like the LLaMA Model requires significant computational resources.
- Quantization limitations: The model has been quantized to 4-bit integers, which can affect its performance or accuracy in certain scenarios.
Format
The LLaMA Model uses a transformer architecture and accepts input in the form of tokenized text sequences.
Input Format
The model expects input data to be in the form of tokenized text sequences. This means you’ll need to split your text into individual words or tokens before passing it to the model.
Tokenization
You can use a tokenizer library to split your text into tokens. The tokenizer will help you convert your text into a format that the model can understand.
Sequence Length
The model has a maximum sequence length of 2048 tokens. If your input text is longer than that, you’ll need to truncate it or split it into smaller chunks.
Supported Data Formats
The LLaMA Model supports the following data formats:
- Text: The model accepts plain text input, which can be tokenized using the
LLaMATokenizer. - Tokenized text: If you’ve already tokenized your text, you can pass it directly to the model.
Special Requirements
- CUDA support: The model requires a CUDA-enabled GPU to run. Make sure you have a compatible GPU installed on your system.
- Quantization: The model uses quantization to reduce its size and improve performance. You may need to adjust the quantization settings depending on your specific use case.
