Swift, UBS, Euroclear, and 20+ organizations are tackling the $58B+ annual corporate actions problem using Chainlink's innovative approach to reduce AI hallucination risks.​

The Solution:

  • Uses multiple LLMs (GPT-4o, Gemini 1.​5, Claude 3.​5) in a consensus framework
  • Instead of trusting a single AI prompt, employs a "swarm" of LLM-prompt combinations
  • Outputs are compared for consensus鈥攊f all models agree, the result can be trusted
  • Converts unstructured corporate action data into machine-readable JSON format

Why It Matters: LLM hallucinations remain a critical barrier to enterprise AI adoption.​ This architecture milestone demonstrates success in managing one of finance's most complex and costly unstructured data challenges.​

Participating institutions include Franklin Templeton, Wellington Management, Vontobel, and Sygnum Bank.​ The framework is designed to work with any LLM model.​
