| Our verdict | LangGraph didn't win the "which agent framework" argument by being the friendliest. It won by being the one that doesn't fall over. | The SDK didn't get replaced by the Agents API. It got a sibling. | This isn't Microsoft's first agent framework. It's Microsoft admitting the first two weren't going to converge on their own. |
