Agent Frameworks
The agent frameworks category shows clear market consolidation around three purpose-built libraries—LangChain, AutoGen, and CrewAI—each achieving 75-82% shortlist rates and maximum model diversity. LlamaIndex maintains strong presence at 66%, while newer entrants like handoff.ai and base.ai capture modest 23-28% adoption. Traditional automation platforms (UiPath, Rasa) struggle with single-digit shortlist rates, suggesting enterprises prefer native LLM-first architectures over retrofitted RPA tools for multi-step agent workflows.
