Cosmos LLaMa Instruct-DPO

This is the newest and the most advanced iteration of CosmosLLama. The model has been developed by merging two distinctly trained CosmosLLaMa-Instruct DPO models.

The CosmosLLaMa-Instruct DPO is designed for text generation tasks, providing the ability to continue a given text snippet in a coherent and contextually relevant manner. Due to the diverse nature of the training data, which includes websites, books, and other text sources, this model can exhibit biases. Users should be aware of these biases and use the model responsibly.

You can easily demo the model from here: https://cosmos.yildiz.edu.tr/cosmosllama
