Generative AI refers to models that may generate latest data samples which might be much like the input data. The success of ChatGPT opened many opportunities across industries, inspiring enterprises to design their very own large language models. The finance sector, driven by data, is now much more data-intensive than ever.
I work as an information scientist at a French-based financial services company. Having been there for over a yr, I’ve recently observed a major increase in LLM use cases across all divisions for task automation and the development of sturdy, secure AI systems.
Every financial service goals to craft its own fine-tuned LLMs using open-source models like LLAMA 2 or Falcon. Especially legacy banks which have a long time of economic data with them.
Up until now, it hasn’t been feasible to include this vast amount of information right into a single model attributable to limited computing resources and fewer complex/low-parameter models. Nevertheless, these open-source models with billions of parameters, can now be fine-tuned to large amounts of textual datasets. Data is like fuel to those models; the more there’s the higher the outcomes.
Each data and LLM models can save banks and other financial services hundreds of thousands by enhancing automation, efficiency, accuracy, and more.
Recent estimates by McKinsey suggest that this Generative AI could offer annual savings of as much as $340 billion for the banking sector alone.
BloombergGPT & Economics of Generative AI
In March 2023, Bloomberg showcased BloombergGPT. It’s a language model built from scratch with 50 billion parameters, tailored specifically for financial data.
To lower your expenses, you sometimes must spend money. Training models like BloombergGPT or Meta’s Llama 2 aren’t low cost.
Training Llama 2’s 70 billion parameter model required 1,700,000 GPU hours. On business cloud services, employing the Nvidia A100 GPU (used for Llama 2) can set one back by $1-$2 for each GPU hour. Doing the maths, a ten billion parameter model could cost around $150,000, while a 100 billion parameter model could cost as high as $1,500,000.
If not renting, purchasing the GPUs outright is an alternate. Yet, buying around 1000 A100 GPUs to form a cluster might set one back by greater than $10 million.
Bloomberg’s investment of over one million dollars is especially eye-opening when juxtaposed against the rapid advancements in AI. Astonishingly, a model costing just $100 managed to surpass BloombergGPT’s performance in only half a yr. While BloombergGPT’s training incorporated proprietary data a overwhelming majority (99.30%) of their dataset was publicly accessible. Comes FinGPT.
