Langtrace AI is a language model observability platform designed to monitor, test, and debug LLM applications. Built for developers, it provides deep tracing and logging for every prompt, system message, and response across any LLM, framework, or architecture. Langtrace captures the full context of language model interactions, enabling detailed analysis, reproducibility, and compliance tracking. This makes it easier to identify hallucinations, latency issues, token overuse, and prompt anomalies. With native integrations for OpenAI, LangChain, and custom APIs, Langtrace acts like a “black box recorder” for AI workflows. It empowers developers to iterate faster while maintaining safety and performance standards across production environments.
