An Open-source LLM for open finance

About FinGPT

FinGPT democratizes Internet-scale data for financial large language models (FinLLMs) at FinNLP.

Why FinGPT?

1). Finance is highly dynamic. BloombergGPT retrains an LLM using a mixed dataset of finance and general data sources, which is too expensive (1.3M GPU hours, a cost of around $5M). It is costly to retrain an LLM model every month or every week, so lightweight adaptation is highly favorable in finance. Instead of undertaking a costly and time-consuming process of retraining a model from scratch with every significant change in the financial landscape, FinGPT can be fine-tuned swiftly to align with new data (the cost of adaptation falls significantly, estimated at less than $416 per training).

2). Democratizing Internet-scale financial data is critical, which should allow timely updates (monthly or weekly updates) using an automatic data curation pipeline. But, BloombergGPT has privileged data access and APIs. FinGPT presents a more accessible alternative. It prioritizes lightweight adaptation, leveraging the strengths of some of the best available open-source LLMs, which are then fed with financial data and fine-tuned for financial language modeling.

3). The key technology is "RLHF (Reinforcement learning from human feedback)", which is missing in BloombergGPT. RLHF enables an LLM model to learn individual preferences (risk-aversion level, investing habits, personalized robo-advisor, etc.), which is the "secret" ingredient of ChatGPT and GPT4.
