Agent Frameworks
Agent frameworks are a three-brand race at the top of AI discovery. LangChain surfaces in 91% of buyer queries across ChatGPT, Claude, Gemini, and Perplexity. AutoGen and CrewAI each appear in 80% of discovery prompts, both visible on all four engines (though CrewAI misses one). LlamaIndex holds the fourth slot at 74%, also ubiquitous across engines. The category is fragmented below that tier—base.ai and handoff.ai split visibility across three or four engines but surface in fewer than 30% of queries. No evaluation-stage data exists yet, so we cannot report who wins head-to-head comparisons. This is a consolidated discovery category: three brands capture nearly all AI attention, with a long tail of niche players fighting for the remaining eyeballs.
