BAND vs OpenAI Agents SDK
SHORT ANSWER
BAND is a client of the agency behind this site.
VERDICT
BAND wins on our weighted rubric (+1.6). Use the SDK for lean agents; use BAND when those agents must work with agents from other frameworks.

How do handoffs differ from rooms?
In the SDK, one agent hands the conversation to another, or a manager calls agents as tools, all inside one process. It is simple and fast to debug. In BAND, agents from different processes, frameworks and vendors share a room and address each other by @mention, with each message tracked per agent.
Why is interop the largest gap?
The SDK supports MCP tools and 100+ model providers, but native A2A is not documented, and it is not listed as a native integration on band.ai/integrations as of September 2026 (OpenAI Codex is listed as a coding agent). BAND's Python and TypeScript SDKs and A2A/MCP support are the route to connect it; check BAND's docs for current options.
What does the Agent Builder wind-down mean?
If you were using Agent Builder to design multi-agent flows visually, that option ends on November 30, 2026. OpenAI points to the Agents SDK for code. For flows that involved agents outside OpenAI, that is a good moment to decide where cross-agent coordination should live.

Can you use BAND and OpenAI Agents SDK together?
Keep SDK agents lean and inside your app. Where they need to work with agents built on other frameworks, or with people, bring them into a BAND room through BAND's SDKs.
Choose BAND if
- SDK agents need to work with agents from other frameworks
- people need a seat in the conversation
Choose the OpenAI Agents SDK if
- you want the fewest abstractions and strong tracing for agents inside one app
