Google's Agent Development Kit (ADK) is an open-source Python framework for building, evaluating, and deploying multi-agent AI systems. It gives developers the orchestration primitives needed to connect multiple AI agents into pipelines, workflows, and hierarchies — so one agent can spawn others, delegate tasks, share context, and coordinate on complex goals. Released alongside Gemini CLI in April 2026, it already has 8,200+ GitHub stars. ADK is model-agnostic but optimized for Gemini. It integrates natively with Google Cloud services including Vertex AI and Cloud Run, making it a natural fit for teams already in the Google ecosystem. Developers can define agent graphs in Python, add tool-calling capabilities, configure memory and state management, and deploy the result as a containerized service or serverless function. The framework enters a competitive space against LangGraph, AutoGen, and CrewAI — but Google's infrastructure integration and the free Gemini CLI tier make ADK a compelling choice for teams that want a managed path from prototype to production without managing their own orchestration infrastructure.

MemOS is an open-source memory operating system designed to give AI agents persistent, manageable long-term memory. Think of it as a unified API layer that handles how AI systems store, retrieve, edit, and delete information across sessions — the same way an OS manages processes and files. Built by MemTensor, it supports text, images, tool traces, and personas through a single interface. The core insight is that current LLM memory is scattered: some in context windows, some in vector databases, some baked into fine-tuned weights, with no unified management layer. MemOS unifies these three memory types (plaintext, activation-based, and parameter-level) under one system. In benchmarks, it reports a 43.7% accuracy improvement over OpenAI's native memory and reduces memory token usage by 35.24% through smarter retrieval and compression. The project is Apache 2.0 licensed, deployable either via cloud API or self-hosted through Docker. It integrates with MCP and supports asynchronous operations with natural language feedback for memory refinement. With 8.7k GitHub stars and over 1,400 commits, it's one of the more mature open-source memory solutions for production agent deployments.
Reviewer scorecard
“If you're already on Google Cloud, ADK is the cleanest path to multi-agent production systems right now. The Python API is intuitive, the Vertex AI integration removes a lot of DevOps overhead, and 8,200 stars in a few weeks means the community is already finding it useful.”
“The unified memory API is what makes this genuinely useful — not having to juggle vector DBs, context stuffing, and fine-tuning separately is a real DX win. 35% token reduction is also meaningful at scale. Apache license and Docker deploy mean it fits into production stacks without legal headaches.”
“LangGraph has a year head-start, a larger ecosystem, and works with every model provider. ADK is arguably just a Google-flavored re-skin with better GCP hooks. Unless you're already committed to Google Cloud, the switching cost isn't worth it yet.”
“The benchmark comparisons against 'OpenAI Memory' are cherry-picked and not independently verified. Long-term memory in LLMs is a genuinely hard problem and a 43% accuracy claim should come with a lot more methodological detail than this repo provides. Self-hosted memory systems also become a liability if they're storing sensitive user data.”
“Multi-agent orchestration is the infrastructure layer that will define how AI systems are built for the next decade. Google open-sourcing ADK while giving away Gemini access for free is a land-grab for developer mindshare — and it's working.”
“Persistent, manageable memory is one of the last major missing pieces for truly autonomous AI agents. MemOS is taking the right architectural approach — unifying memory types rather than bolting on another vector DB — and the OS analogy is apt. This category is going to matter enormously.”
“For content teams building automated pipelines — research agents feeding writing agents feeding publishing agents — ADK provides the connective tissue without requiring a backend engineer to wire it all together. The visual graph debugging alone is worth the switch from manual chaining.”
“For creative workflows where I want an AI to actually remember my style, past projects, and preferences across sessions, this is exactly what's been missing. The multi-modal memory support (text + images) makes it useful for design workflows too, not just text-heavy agent tasks.”
