Turkish-Gemma-9b-v0.1

This is the Turkish-Gemma-9b-v0.1. This model is based on Gemma-2-9b, and was developed through a combination of continual pre-training, supervised fine-tuning (SFT), direct preference optimization (DPO), and model merging.

The Turkish-Gemma-9b-v0.1 is designed for Turkish text generation tasks, providing coherent, contextually relevant continuations and answers. Due to the diverse nature of the training data—which includes large-scale pre-training corpora, instruction-tuning data, and human preference data—the model may exhibit biases. Users should be aware of these and deploy the model responsibly.

You can easily demo the model here (Coming soon!): https://cosmos.yildiz.edu.tr/cosmosllm

To evaluate model performance, we compiled a dataset of 1,450 carefully designed questions across diverse categories. Each question was reviewed and rated by 18 human annotators, allowing for a reliable comparison across multiple models.

The table below summarizes the evaluation results:

🏆 Model Comparison: Win Rates

Voting Metodology

A question and two answers from different models were presented to human judges. The judges selected the better answer based on their preferences. For example, in the question below, the judge selected the answer on the right:

# RD(X) = X ifadesi, bir sayının çarpmaya göre tersinin kendisiyle eşit olması anlamına gelir. Yani, X ile 1/X aynı olmalıdır. Bu durum yalnızca X'in karesi 1 olduğunda gerçekleşir:

# X² = 1

# Bu denklemin çözümleri:

# X = 1 ve X = -1

# Dolayısıyla, RD(X) = X eşitliğini sağlayan *iki* X değeri vardır: *1* ve *-1*.
