Executive Summary

The rise of agentic infrastructure and what you need to know.

The transition from passive Chatbots to active AI Agents has created demand for specialized infrastructure. Standard LLM APIs are insufficient for agents that need to control browsers, execute code, and maintain persistent state. The market is bifurcated into Orchestration Frameworks (the Brain) and Execution Environments (the Hands).

  • Primary Bottleneck: Context windows remain the critical limitation for complex agent state
  • Dominant Stack: LangChain + E2B is the most common pairing in production deployments
  • Emerging Standard: MCP (Model Context Protocol) is gaining rapid adoption for tool integration
  • Top Pain Point: Looping errors where agents get stuck are the #1 user complaint
ℹ️ Info

A 95% success rate per step leads to only 59% success in a 10-step workflow. Reliability compounds negatively.

⚠️ Warning

Agent infrastructure is still nascent. Expect rapid changes and evaluate tools quarterly.
