Accelerate agentic tool calling with serverless model customization in Amazon SageMaker AI
Amazon SageMaker just made agentic AI 10x faster to build. Here's how enterprises deploy custom tool-calling agents in hours, not months.
Why it matters
AWS is lowering the barrier to entry for enterprises building production AI agents by offering serverless model customization. This directly impacts how companies can deploy agentic workflows at scale without managing infrastructure.
