# Plus backbone and MCP tools for Neural Architecture Search

Neural Architecture Search now supports the Plus backbone for object detection. Plus discovers more accurate models and is best when you plan to deploy on cloud GPUs.

NAS training is also now available through the Roboflow MCP Server. Coding agents like Claude Code, Cursor, and Codex can start a NAS run, list and compare NAS and non-NAS models across a workspace, and pick a model to deploy through MCP.
