Financial services are facing a new reality: Generative AI is transforming the industry. While closed source models offer powerful capabilities, they can raise concerns about transparency and control. This is where open source masters come into play. Now more advanced than ever, these models provide a flexible and secure foundation for building AI-powered solutions. With open source, financial institutions can embrace innovation while maintaining control over their data and algorithms.

Gaurav Sharma, Client Partner, Fractal Financial Services, said: AIM To explore this shift and explain how open source LLMs are being used in financial services.

Sharma emphasized the critical importance of data protection when distributing open source LLMs. Businesses must ensure strict adherence to data privacy laws and regulations. This includes minimizing data collection, appropriately filtering content, and distributing models locally where possible. Techniques such as anonymization, serialization, and differential privacy are essential tools for protecting sensitive information.

Developed a framework for managing data privacy: detect, treat and rehydrate. Detection involves identifying potential risks to personal or sensitive information. Treatment addresses these risks through processes and governance structures, while rehydration focuses on integrating findings into policy and governance.

Sharma emphasized the need for strong encryption protocols, data anonymization and comprehensive data governance policies to protect sensitive information

The regulatory environment poses significant challenges when using open source Masters. Sharma identified four key concerns: data privacy, bias and fairness, explainability, and scalability. “Data privacy involves handling sensitive information in accordance with regulations. Anti-bias and fairness require addressing ethical considerations and ensuring fair model outcomes,” noted Sharma.

Explainability is another critical area. “Regulations often require model decisions to be explainable in simple terms. “The ability to express how models work and make decisions is crucial for compliance,” he added. Sharma also noted the need for scalability and efficiency, which ensures LLMs can grow with organizational needs while maintaining performance standards.

Bias Reduction and Model Explainability

Biases in open source graduate education are a serious concern. “To mitigate these, use diverse datasets and employ robust bias detection and mitigation techniques throughout the model lifecycle,” said Sharma.

“Transparency and accountability are very important. “Tools like LIME (Local Interpretable Model-Agnostic Explanations) can help explain model decisions and increase confidence,” he said.

Explainability is important to understanding and trusting open source masters. Sharma emphasized the use of tools and techniques that allow users to explore model predictions and interactively understand the results. “Combining attentional mechanisms and saliency maps can provide insights into model predictions and facilitate the explanation of decisions in natural language,” he explained.

Performance and Customization

Regarding performance, Sharma acknowledged that while open-source LLMs initially lagged behind proprietary models, they are improving rapidly. “Open source models such as GPT-Neo, Mistral and Llama are now performing at levels comparable to proprietary models. Companies are realizing the potential of these models, with usage shifting from 80-20 to a more balanced 50-50 in favor of proprietary models,” he said.

Customization is a key advantage in open source LLMs. Sharma underlined that open source models offer flexibility to tailor solutions to meet specific financial regulations and requirements. Customization allows models to be fine-tuned to meet unique financial needs and compliance standards. This provides the opportunity to develop highly specialized applications, although this requires resources.

Hidden Costs and Security Considerations

However, Sharma warned of hidden costs associated with open source graduate studies. “The initial investment in computer resources, development and maintenance is significant. Customization requires expertise and continuous effort. “Unlike proprietary models that offer ready-to-use solutions, open source LLMs require a significant amount of in-house development,” he said.

Other costs include ensuring regulatory compliance and integrating models into existing systems. Sharma noted that open source solutions’ security measures, regulatory compliance, and integration into business processes need to be carefully evaluated. The need for continuous performance optimization and support adds to the overall investment.

Moreover, hiring the right talent requires capital. After the initial investment in IT, companies need good talent to keep the system flowing throughout adoption. “You need to have the right expertise to move this forward.”

Preventing misuse of open source masters is critical. Sharma talked about best practices to reduce risks such as malware and harmful content. Exposing LLMs to adversarial examples during training, implementing robust input validation, and controlling access are important steps.

“Ensuring appropriate security environments and feedback loops helps protect against malicious activity,” he said.

Adoption and Scalability

Sharma noted that companies are hesitant to adopt open source master’s programs, especially as discussions about scalability gain momentum. “When companies talk about generative AI and all the fancy stuff, they also want to talk about POCs,” said Sharma.

Companies need to be engaged in moving LLMs forward, as every company has different needs and what works right for them. “I think companies need to figure out where they stand on various levels before moving forward,” Sharma added, saying they are “learning and growing” when it comes to the long-term sustainability of these open source graduate courses.

As a few companies begin to adopt a particular LLM, others begin to learn and grow along the way. “It requires a lot of investment, but then that investment will pay off.”

“Sustainability is very important,” emphasized Sharma. “We are currently in the awareness phase, but assimilation and adoption will follow.”
