Is the new OpenAI Agents SDK robust enough to replace LangChain for production-grade AI agents?

All answers to this question.

We migrated our customer support bot to the OpenAI Agents SDK last month, and the stability improvement was immediate. Unlike LangChain, which often feels like it's fighting against the underlying model's logic, this SDK feels native. The "handoff" primitive is incredibly clean; it allows one agent to delegate to another without losing context or blowing up the token count. While it lacks the 1,000+ integrations LangChain offers, the core primitives—Agents, Tools, Handoffs, and Guardrails—are actually all you need for 95% of production use cases. It’s less about "replacing" and more about "simplifying" your stack to something that won't break every time a dependency updates.

That's an interesting take, Sarah. But how does the OpenAI Agents SDK handle long-term memory or RAG? LangChain has built-in vector store wrappers that make retrieval-augmented generation almost plug-and-play. Does this new SDK force you to build those memory layers manually from scratch?

• You're right, Jason, it doesn't have a "VectorStore" class. However, you can just use the FileSearch tool or wrap your own vector DB call in a standard Python function. It doesn't provide the wrapper because it assumes you want to control your own data layer. For a production app, I actually prefer this over an opinionated framework that hides the DB logic.

I find that the built-in tracing in the OpenAI Agents SDK is its secret weapon. Being able to see exactly where a handoff failed in the OpenAI dashboard is a game changer for our dev team.

• Totally agree, Megan. The observability is light years ahead. We used to spend hours digging through LangSmith logs, but having it integrated into the provider's own platform saves so much time.
