Google ADK 2.0 vs ml-intern

Google's Agent Development Kit (ADK) just hit two major milestones simultaneously: ADK Python 2.0 Beta with workflows and agent teams, and ADK TypeScript 1.0 reaching stable release. This open-source framework is Google's answer to LangChain and CrewAI — a code-first toolkit for building production-grade AI agents that are testable, versionable, and deployable anywhere. What separates ADK from the competition is its context management philosophy: it treats sessions, memory, tool outputs, and artifacts like source code, assembling structured context where "every token earns its place." The 2.0 beta introduces graph-based workflows and collaborative multi-agent systems, letting developers compose teams of specialized agents into complex hierarchies. It's model-agnostic despite being optimized for Gemini, and supports MCP natively. Deployment is a first-class citizen — native integrations with Cloud Run, GKE, and Vertex AI Agent Engine, plus Google's new Agents CLI for scaffolding, eval, and deploy in one command. With Apache 2.0 licensing and a bi-weekly release cadence, this is shaping up as the enterprise-grade foundation serious agent builders have been waiting for.

ml-intern is Hugging Face's own open-source autonomous ML engineering agent. Given a task description, it reads relevant papers, writes training code, executes it in a sandboxed environment, evaluates the results, iterates, and ultimately uploads a trained model to the Hugging Face Hub — with no human in the loop beyond the initial prompt. Under the hood, the agent runs an agentic loop of up to 300 iterations, using Claude as its reasoning backbone alongside smolagents. It has integrated access to HF documentation search, paper retrieval, GitHub code search, and sandboxed Python execution. When the context window fills (at 170k tokens), it auto-compacts rather than failing, and full sessions are uploaded to HF for inspection and reproducibility. What's notable here isn't just the capability — it's the source. Hugging Face is essentially shipping a proof-of-concept that the job of "write the ML training script, run it, fix it until it works, upload the result" can now be delegated to an agent. With 688 stars and active development as of this week, ml-intern is HF eating its own dog food on autonomous AI engineering. The "doom loop detector" that flags repetitive tool-use patterns is a candid acknowledgment of how agentic loops fail in practice.
