Cohere has unveiled a new programmatic fine-tuning feature for its Python SDK, allowing developers to integrate fine-tuning into their workflows more seamlessly than before. Previously limited to the Cohere Dashboard, this enhancement offers automation, version control, and reproducibility, streamlining the process of customizing pre-trained language models for specific tasks. By utilizing the SDK, developers can automate fine-tuning, manage code with version control systems like Git, and ensure reproducibility by defining, training, and fine-tuning models through code. The process involves using the `create_custom_model` method with essential and additional parameters, enabling efficient model customization. This development empowers users to harness Cohere's advanced language models more effectively, opening up possibilities for tailored applications across various industries.
