Aveni Unveils Next Iteration of FinLLM setting AI Safety Standards for Agentic AI Adoption in UK Financial Services

Aveni, the leading UK AI Fintech, has today announced the next iteration of FinLLM – the UK’s first domain specific Large Language Model for the Financial Services sector. First unveiled in May 2025, FinLLM has rapidly evolved to become the most advanced AI model tailored for the UK’s financial sector.

Trained on domain specific data and tested against real world use cases, this version of FinLLM delivers higher accuracy, efficiency and critically, a new safety framework for agentic AI adoption across financial services; particularly crucial as the industry looks at greater use of AI agent models to support customer service interaction and, eventually, advice. 

FinLLM has integrated the  NVIDIA NeMo and leveraged NVIDIA accelerated computing to train the model.  FinLLM is closely aligned with NVIDIA’s vision for agentic AI, which emphasises the role of Small Language Models (SLMs) in delivering safer, more efficient, domain specialised intelligence. FinLLM embodies this approach by distilling only the most relevant financial knowledge, removing irrelevant material, and improves the responsible deployment of SLMs in regulated industries. 

Aligned with FCA regulatory priorities and focused on customer outcomes, the model is deployed through Aveni’s Assurance Platform and embedded within Aveni’s flagship products – Aveni Detect and Aveni Assist – providing financial institutions with the confidence to adopt AI responsibly as they transition to the next generation of agentic domain-specialised AI systems. 

Joseph Twigg, CEO at Aveni commented: “AI-backed agents will take on autonomous roles within financial services, with AI agents or bots supporting direct customer interactions at scale, and this requires a new class of assurance to govern their behaviour and manage risks. That means the right advice and responses being available to the AI models, built with a clear understanding of FCA guidelines and associated guardrails in place to deliver the customer outcomes and meet Consumer Duty compliance. 

“Our work with NVIDIA, alongside industry partners Lloyds Banking Group and Nationwide, means FinLLM is not only technologically advanced but also deeply relevant to the realities of FS. This is the foundation of safe, scalable adoption of agentic AI across the sector.” 

Lloyds Banking Group and Nationwide have also been working with Aveni through a collaborative engagement to ensure that FinLLM capabilities are grounded in real-world applications and industry needs. Their input has influenced the technical build and Aveni’s approach to governance and risk.
