Helicone, an open-source platform designed to enhance the development lifecycle of LLM applications, has introduced significant updates with its V2 release, focusing on comprehensive logging, evaluation, experimentation, and release processes. Originally launched to provide visibility into LLM applications, Helicone has processed over 2.1 billion requests and 2.6 trillion tokens, supporting a wide range of companies from startups to Fortune 500 firms. The new workflow in Helicone V2 aims to address the challenges of managing production-grade applications by offering tools for prompt management, evaluations, and systematic experimentation to improve application performance iteratively. The platform's infrastructure has been revamped to accommodate growth, using Kafka for log processing and improving storage efficiency with S3, Kafka, and ClickHouse, ensuring fast query times even at high volumes. Helicone encourages user feedback and contributions via Discord and GitHub and offers a free demo and self-hosting options for users to explore its features and improvements.
