Nexus

Nexus is an AI engineering platform designed to monitor, debug, and improve autonomous AI agents in real time. Its primary purpose is to give teams visibility into how their agents behave in production and to automatically detect, diagnose, and correct failures before they impact users. By acting as an “AI engineer” alongside your deployed systems, Nexus helps ensure reliability, safety, and predictable performance for complex agent workflows.

Nexus continuously observes agent runs, capturing detailed traces of prompts, model responses, tool calls, and environment interactions. It identifies issues such as hallucinations, broken tool integrations, looping behavior, or unmet user goals, and can apply predefined or learned fixes on the fly. The platform provides a rich debugging interface with step-by-step execution views, error surfaces, and performance metrics so teams can quickly understand and reproduce problematic behavior. Nexus also supports policy enforcement, guardrails, and evaluation hooks, enabling systematic testing and improvement of agents over time.
