Deprecation Notice: NVIDIA NeMo Agent Toolkit has been deprecated as of October 2026 and will reach end of life (EOL) by end of year 2026. Depending on your needs, migrate to: NeMo Relay for observability, middleware, and governance. NeMo Helix for a unified CLI with evaluation, optimization, and hardening capabilities. NeMo Fabric for a consistent interface to run agent harnesses and custom agents. We recommend completing your migration before the EOL date.
