Agent Lightning is Microsoft's open-source framework for training, fine-tuning, and optimizing AI agents without rewriting your existing code. The core idea: add lightweight emit() calls (or enable auto-tracing) to capture prompts, tool calls, and reward signals as structured spans. Those spans flow into LightningStore, which feeds a pluggable Trainer that can run reinforcement learning, automatic prompt optimization, supervised fine-tuning, or custom algorithms — your choice. What makes it notable is genuine framework agnosticism. Whether your agents are built on LangChain, AutoGen, CrewAI, OpenAI's Agent SDK, or plain Python with OpenAI, Agent Lightning bolts on without architectural changes. You can target specific agents within a multi-agent system and leave others untouched. With 16.8k GitHub stars and a Discord community, Microsoft is positioning this as the training layer that sits beneath whatever orchestration framework developers already use. That's a smart wedge: rather than competing with LangChain or AutoGen for framework mindshare, it becomes the optimization pass that makes all of them better.

WUPHF
Open-source multi-agent 'office' — AI teams that think together

WUPHF is an open-source orchestration system that turns multiple LLM agents into a visible, collaborative 'office.' Spawn a CEO, PM, engineers, and designers as agents running simultaneously — all able to @mention each other, claim tasks, and maintain a shared wiki of knowledge. It's like GitHub for agent thought. The architecture is cleverly frugal: instead of accumulating context, WUPHF uses fresh sessions per turn with Claude's prompt caching, hitting 97% cache hit rates and dropping five-turn sessions to roughly $0.06. Agents are push-driven — they only wake when notified, meaning zero idle token burn. A dual memory system (per-agent Notebooks + shared Wiki) keeps the team aligned across sessions. Built by indie developers and spotted trending on Hacker News, WUPHF targets the rapidly growing segment of builders who want more than one AI "employee" but don't want to pay enterprise orchestration prices. Telegram bridge, Composio integration, and a clean web UI at localhost:7891 round out the package.
Reviewer scorecard
“Framework-agnostic agent training is the gap nobody talks about. Most teams are spending weeks retrofitting optimization logic into agents built on whatever framework they grabbed first. Agent Lightning's emit() approach is low-ceremony and the RL + prompt optimization combo in one package is genuinely useful.”
“The token-efficiency story alone makes this worth trying — $0.06 for a five-agent session is remarkable. The @mention graph and shared wiki are genuinely novel patterns that every multi-agent framework should steal.”
“Microsoft has a habit of open-sourcing research-grade tools that look polished in demos but lack production hardening. The reward signal design problem — which is 80% of the real work in RL for agents — is entirely on the developer. The framework just runs your reward function, it doesn't help you define a good one.”
“The 'AI office' metaphor sounds fun until you're debugging why the agent-CEO contradicted the agent-PM three turns ago. Fresh-session architecture fixes cost but breaks longitudinal reasoning — agents can't truly learn from mistakes across days.”
“The real long-term play here is continuous agent improvement in production — agents that get better the longer they run on real user data. Agent Lightning is one of the first frameworks that makes this pattern tractable for teams without ML research backgrounds. This is how production AI systems will be maintained in 2027.”
“This is what agent-native software development looks like before the big platforms catch up. The Telegram bridge and push-driven activation pattern hint at a world where your 'team' lives in your chat app, not a browser tab.”
“The name and branding are oddly compelling for a Microsoft project. The 'absolute trainer' positioning is confident without being cringe. The docs site is clean and the architecture diagrams actually explain the system rather than just looking impressive.”
“Being able to spin up a dedicated 'creative director' agent alongside your developer agents is genuinely useful. The visible activity stream means you can actually see the creative process unfolding in real-time.”
