Cohere has introduced fine-tuning capabilities for its Chat endpoint, allowing developers to customize AI-powered chatbots to meet specific style and knowledge requirements, thus enhancing user engagement and satisfaction. This customization is particularly impactful in specialized roles, such as hotel concierges, IT customer support, and internal finance assistants, where chatbots can be tailored to exhibit domain-specific behaviors and language. An experiment with the ConvFinQA system demonstrated the effectiveness of fine-tuning by improving the accuracy of financial query responses to 68.1%, highlighting the potential for tailored chatbots to outperform generic models in specialized contexts. Developers can access these fine-tuning capabilities programmatically through an SDK or Cohere’s new interface, with additional documentation available for further guidance.
