tiny LlamaForCausalLM 3

The *tiny LlamaForCausalLM 3* model is a lightweight and simplified version of the Llama model, specifically designed for unit testing within the TRL library. It retains the core capabilities of a causal language model, enabling autonomous text generation by predicting the next word in a sequence. Despite its reduced size, it provides a functional foundation for validating features or integrations without requiring significant computational resources. Its main advantage lies in its compactness and fast execution speed, making it ideal for quick checks or development environments. It is particularly useful for developers working on tools related to reinforcement learning or language model optimization.
