With the launch of GPT-4o, OpenAI's advanced multimodal and multilingual model, transitioning from an existing model can be challenging due to potential risks and time constraints. Helicone offers a solution to facilitate this transition by using its experiments feature to safely test and compare the new model against the current one. The process involves using Helicone's prompt templating feature to log prompts, set up experiments with the GPT-4o model, and analyze the results to make informed decisions about switching. This method allows users to conduct regression tests and evaluate model performance without affecting end-users. Helicone's approach enables users to experiment with production data and prompts confidently, fostering innovative developments while ensuring quality and stability in their applications.
