RL X-mas came early. 🎄 For too long, building powerful AI agents with Reinforcement Learning has been blocked by GPU scarcity and complex infrastructure. That ends today. Introducing Serverless RL from wandb, powered by CoreWeave! We're making RL accessible to all.

Every run starts with a question. Can we make this model better? You've now asked it 1,000,000,000 times. (how many failed? No comment 😂) Thank you doesn't cover it, but thank you.

Hey MCP developers! Let’s talk about something broken 🧠🛠️ Agents are calling tools left and right. But what happens inside those tools? No traces. No visibility. No security. Just a black box. 🕋 The observability gap is real. Let's fix it together with observable[.]tools
