FinGPT

FinGPT is an open-source financial large language model framework developed by the AI4Finance Foundation. It provides a data-centric approach to building financial AI, offering researchers and practitioners accessible tools to develop and customize their own financial LLMs using lightweight low-rank adaptation (LoRA) techniques. The framework excels at financial sentiment analysis, achieving scores comparable to GPT-4 on news and social media datasets, while running on a single consumer GPU. FinGPT supports multiple base models including Llama 2 and ChatGLM, and includes RAG capabilities for enhanced financial document analysis. With fine-tuning costs under $300 per run (compared to millions for models like BloombergGPT), FinGPT democratizes access to financial AI. It covers use cases from robo-advising and algorithmic trading signals to earnings call analysis and financial report summarization. Models are published on HuggingFace for easy deployment.
