AI agent training loop with multiple agents feeding one optimizer

Microsoft Agent Lightning keeps momentum as a no-rewrite training route for existing agents

Agent Lightning positions itself as a trainer for existing agents with near zero code change, backed by an arXiv paper on reinforcement learning for agent systems.

Agent teams often hit a wall when they try to optimize deployed systems without rebuilding everything. Microsoft Agent Lightning targets that gap.

The project README describes support for many frameworks and near zero code change integration. The related paper, arXiv:2508.03680, was submitted on August 5, 2025 and focuses on reinforcement learning for agent workflows.

What matters now is adoption quality, not launch hype. Teams care about whether these loops improve production outcomes without adding brittle ops overhead.

A related long-horizon coding benchmark comparison appears in our coverage of the Composer 2 technical report.

Implementation details and framework notes are published in Microsoft's Agent Lightning repository.
