Overview
Finetunned based on TinyLlama 1.1B Chat is a language model designed for various natural language processing tasks. It utilizes the Llama architecture with a substantial number of hidden layers, attention heads, and a large vocabulary size. The model is trained to generate text in a causal manner, which means it predicts the next word in a sequence based on the preceding context.
Key Features
- Large vocabulary size of 32,000 words.
- High hidden size (2,048) and intermediate size (5,632) for enhanced modeling capability.
- 32 attention heads for capturing complex relationships in text.
- 22 hidden layers for deep context understanding.
- Utilizes silu (Sigmoid Linear Unit) as the hidden activation function.
- Transformer version 4.35.2.
- Supports cache for faster text generation.
Pretraining
The model has undergone pretraining with a pretraining task weight of 1.
Additional Information
- Attention Bias is disabled in this model.
- Word embeddings are not tied.
- Max position embeddings support sequences up to 2,048 tokens.
- RMS normalization epsilon is set to 1e-05.
- Rope scaling and theta are specified as null and 10,000.0, respectively.
Disclaimer
While this model can generate text, it should be used responsibly and ethically. It may generate inappropriate or biased content, and it is the responsibility of users to filter and moderate the output.
