At Whatfix, we continually explore various models to address different tasks. Currently, the following models are in use; however, they might change in the future: **Custom Pipeline**: Our custom pipeline incorporates multiple models specifically designed for different preprocessing tasks. These models, such as text-curie and text-ada, derive from the powerful GPT-4o model. These variants tailor to our specific requirements and enhance the performance of our pipeline. **Summarization**: For tasks involving summarization, we use GPT-4o. This model, developed by OpenAI, enables the generation of accurate summaries and provides relevant suggestions to enhance user experience and productivity.
