Helicone offers AI engineers and LLM developers a suite of features designed to enhance the performance of their applications by optimizing response times, reducing costs, and improving reliability. The platform's four core features—custom properties, sessions, prompt management, and caching—allow developers to tailor analytics, debug complex workflows, version and optimize prompts, and reduce latency through caching. Integrating Helicone is straightforward, requiring only a single line of code adjustment to work with various AI models and APIs. Custom properties enable data-driven improvements by segmenting requests, while sessions provide insights into multi-step workflows. Prompt management facilitates iterative improvements in AI prompts, and caching enhances performance by storing responses for quick retrieval. These features collectively offer developers practical, implementable solutions to optimize their AI applications, all while maintaining compatibility with existing workflows and providing deep insights into user interactions and application performance.
