The editorial take
Choose Google ADK if you want a multi-model framework (Gemini, Claude, GPT-4, open-source) with built-in evaluation and four language SDKs. Choose OpenAI Agents SDK if your stack is OpenAI-first and you want the simplest path to building agents with GPT models and OpenAI's tool ecosystem.
Google ADK - Pros & Cons
Pros
- ✓Code-first abstractions support versioning and testable agent behavior
- ✓Evaluation and deployment workflows address more than prompt prototyping
- ✓Natural fit for teams already using Gemini and Google Cloud
Cons
- ✗Requires software engineering skills and operational ownership
- ✗End-to-end cost depends on separate model and cloud services
- ✗Deep Google integration may reduce portability to other stacks
OpenAI Agents SDK - Pros & Cons
Pros
- ✓Small, Python-first abstraction layer makes it easier to learn than heavier orchestration frameworks.
- ✓Official OpenAI support and default Responses API integration reduce glue code for OpenAI-based apps.
- ✓Built-in tracing, guardrails, handoffs, sessions, and MCP support cover common production agent needs.
- ✓Sandbox agents are useful for coding, document, and workspace tasks that need files, commands, and resumable state.
- ✓Open source package means teams can inspect the runtime instead of relying only on a hosted black box.
Cons
- ✗It is a developer framework, not a no-code builder; Python experience is required for meaningful use.
- ✗The SDK is free, but real deployments still incur OpenAI API, realtime voice, tool, sandbox, and hosting costs.
- ✗Pricing isn't clearly published on the OpenAI pricing page; check the vendor's site for current plans.
- ✗Teams still need to design permission boundaries, evals, logging, data retention, and human review processes.
- ✗Best experience is likely with OpenAI models, even though third-party model adapters exist.
