Between October and early December, Microsoft unified AutoGen and Semantic Kernel. OpenAI launched AgentKit with visual workflow builders. Google released ADK at Cloud NEXT. AWS announced AgentCore hit 2 million downloads in five months. Adopt AI shipped their framework too.
Watch what they're all building: MCP support, agent-to-agent communication, visual orchestration tools. The features are nearly identical because the goal is identical. Control the orchestration layer, control the enterprise AI stack.
This is a land grab. The vendors see what's coming. Multi-agent systems need coordination infrastructure, and whoever provides that infrastructure becomes the platform everyone else builds on top of. We've seen this movie before with integration platforms and customer data platforms. Orchestration is the new battleground.
