The collaboration integrates Arize's LLM evaluation and observability platform with Azure's Model as a Service, offering users access to popular open-source models curated by Azure AI. This partnership aims to speed up the reliable deployment of LLM applications while ensuring robust ML and LLM observability for Fortune 500 companies using Azure along with Arize. The integration also provides tools for collecting evaluation data, troubleshooting search and retrieval, and tracing to see where an LLM app chain fails.
