The rollout aims to accelerate software development, modernize legacy systems, and improve operational efficiency. Barclays expects Claude Code adoption to reach 50% of developers by end-2026, growing to a majority in 2027. A live Colleague Knowledge Assistant powered by Claude using retrieval-augmented generation (RAG) has been adopted by 16,000+ staff and processed over 1M searches since 2025. In Global Markets, Claude models classify and route ~120,000 incoming emails daily, reducing manual work while improving decision speed. The focus is on responsible AI governance at scale in a highly regulated sector.

Barclays' implementation leverages retrieval-augmented generation (RAG) architecture for the Colleague Knowledge Assistant, integrating Claude with internal knowledge bases. The Global Markets email routing system uses Claude for classification, enrichment, and optimal process routing, handling ~120,000 emails daily in production. Specific API versions, context window size, and rate limits are not disclosed, but enterprise-grade governance features (audit logs, access controls, content filtering) appear central to the deployment. The system has been live since 2025, suggesting Claude 3.5 Sonnet or later. Use cases span productivity (faster information access) and security (automated code review, modernization of legacy platforms). No specific pricing or tokens-per-minute allocation is mentioned, implying volume-based negotiation.
