FinGPT is an open-source financial large language model developed by the AI4Finance Foundation, designed to democratize financial AI research and development. With over 14,000 GitHub stars, it is one of the most popular open-source projects in the financial AI space.
Built on top of Meta's Llama architecture, FinGPT uses LoRA (Low-Rank Adaptation) fine-tuning to adapt the base model for financial tasks. The project provides multiple fine-tuned variants optimized for different financial applications, including sentiment analysis, financial text generation, and stock movement prediction. The training data spans financial news, SEC filings, earnings call transcripts, and analyst reports, giving the model broad financial domain coverage.
The MIT license makes FinGPT one of the most permissively licensed finance LLMs available, allowing both academic research and commercial experimentation. While it is a research project rather than a production-ready system, FinGPT has become a foundational platform for the financial AI research community, spawning numerous derivative models and specialized fine-tunes for specific financial workflows.
