Alyx is Arize's new AI agent, evolved from the previous Copilot tool, designed to enhance user interactions by providing continuity and context in large language model (LLM) workflows. Unlike Copilot, which offered basic task assistance and limited memory capabilities, Alyx adopts an "Agent Mode" for more complex interactions, allowing users to guide the assistant with specific context, such as datasets or eval explanations, which improves accuracy and reliability. This evolution addresses the need for a more integrated and effective collaboration, moving beyond simple task delegation to support multi-step, iterative processes. Arize envisions Alyx as a proactive partner, capable of planning, retaining state, and driving towards outcomes, with future plans for deeper workflow integrations and broader accessibility across various platforms.
