Stop Building Agent Loops. This Is Replacing Them

Thanks to n8n for sponsoring this video: https://plug.dev.plug.dev/kY17OO2 Google just shipped Managed Agents in the Gemini API as part of Antigravity 2.0 — six weeks after Anthropic launched their own version. In this video, I walk through what Managed Agents actually are, the four places where the Anthropic and Google implementations diverge, and the vendor-lock-in trap most teams underestimate. Plus the Google Enterprise tier almost nobody is talking about. === KEY LINKS === Anthropic Managed Agents — engineering blog: https://www.anthropic.com/engineering/managed-agents Anthropic Managed Agents — docs: https://platform.claude.com/docs/en/managed-agents/overview Google Managed Agents — launch announcement: https://blog.google/innovation-and-ai/technology/developers-tools/managed-agents-gemini-api/ Google Antigravity Agent — Gemini API docs (consumer version): https://ai.google.dev/gemini-api/docs/antigravity-agent Google Managed Agents — Enterprise Agent Platform (the version with MCP + OAuth + Memory Bank, private preview): https://docs.cloud.google.com/gemini-enterprise-agent-platform/build/managed-agents My voice to text App: whryte.com Website: https://engineerprompt.ai/ RAG Beyond Basics Course: https://prompt-s-site.thinkific.com/courses/rag Signup for Newsletter, localgpt: https://tally.so/r/3y9bb0 Let's Connect: 🦾 Discord: https://discord.com/invite/t4eYQRUcXB ☕ Buy me a Coffee: https://ko-fi.com/promptengineering |🔴 Patreon: https://www.patreon.com/PromptEngineering 💼Consulting: https://calendly.com/engineerprompt/consulting-call 📧 Business Contact: [email protected] Become Member: http://tinyurl.com/y5h28s6h 💻 Pre-configured localGPT VM: https://bit.ly/localGPT (use Code: PromptEngineering for 50% off).

I explain the managed-agent runtime idea (model/brain, tools/hands, and a durable session log) and why providers are absorbing the orchestration layer. Then I compare Anthropic’s deeper, multi-resource API (versioned agents, environments, sessions, typed event streams, interruptions) with Google’s simpler single-call approach in Gemini API, plus differences in tools, MCP support, OAuth vaults, memory features, and pricing. I also cover Google’s separate Gemini Enterprise Agent platform (private preview) that adds MCP, auth manager, memory bank, and skills. Finally, I discuss tradeoffs like vendor lock-in, model behavior drift, and preview limitations. 00:00 Managed Agents Trend 01:04 What Managed Agents Are 02:19 Brain Hands Session Model 03:54 Real World Pain Points 07:05 Sponsor n8n MCP Demo 10:27 Anthropic vs Google APIs 12:15 Tools Memory And Extras 14:22 Runtime Hosting And Pricing 17:08 Depth vs Simplicity Bets 19:16 Cost Speed And Value 21:42 Vendor Lock In And Drift
