BloombergGPT
BloombergGPT is Bloomberg's in-house large language model for financial natural language processing inside the Bloomberg Terminal. The 50.6-billion-parameter decoder was announced in March 2023 with a public research paper, and it targets sentiment analysis, named entity recognition, news classification, charting, and question answering over Terminal data. It is not a standalone chatbot or a public API you can sign up for on your own.
Most finance-focused language models train only on domain text, which helps niche benchmarks but often weakens general reasoning. BloombergGPT took a mixed training path: roughly half its 700-billion-token corpus is FinPile, Bloomberg's curated financial archive spanning filings, news, press releases, and web sources, and the rest comes from public datasets like The Pile, C4, and English Wikipedia. Bloomberg reports the model beats similarly sized open models on financial tasks without giving up ground on general NLP benchmarks.
The model serves Bloomberg Terminal subscribers such as portfolio managers, equity research analysts, and quantitative teams who need finance-aware language understanding inside existing workflows. Bloomberg has extended Terminal features with BloombergGPT-backed earnings call summaries, news summaries, document search, and deeper Q&A over content already in the platform.
50.6 billion parameters across 70 transformer layers, trained on 569 billion tokens
FinPile corpus combines 363 billion financial tokens with 345 billion public tokens
Outperforms similarly sized open models on financial benchmarks in Bloomberg's published research
Powers Terminal sentiment analysis, entity recognition, news classification, charting, and Q&A
BLOOM-style decoder with a 131,072-token vocabulary and 40 attention heads
Trained on 64 clusters of 8 NVIDIA A100 40GB GPUs per the research paper
Trained on FinPile, Bloomberg's curated financial archive built from decades of filings, news, and market documents.
Mixed finance and general training keeps strong scores on non-financial NLP benchmarks alongside finance tasks.
Integrated into Bloomberg Terminal workflows rather than a separate tool subscribers must manage.
Bloomberg's published research documents architecture, training data, and benchmark results in detail.
No public API or standalone access outside Bloomberg's paid Terminal ecosystem.
Practical use requires a Bloomberg Terminal subscription with enterprise sales contact.
The announcement page and research paper describe the model, not a self-serve signup product.
What is BloombergGPT?

Is BloombergGPT a chatbot like ChatGPT?
No. Bloomberg states BloombergGPT is not a chatbot. It backs Terminal features such as sentiment analysis, named entity recognition, news classification, charting, and question answering that help users surface content already in the platform.
How large is BloombergGPT?
BloombergGPT has 50.6 billion parameters, 70 transformer layers, 40 attention heads, and a 131,072-token vocabulary. Bloomberg's research paper reports training on 569 billion tokens from a corpus exceeding 700 billion tokens.
What data trained BloombergGPT?
BloombergGPT trained on FinPile, a 363-billion-token financial dataset drawn from Bloomberg archives, plus 345 billion tokens from public sources such as The Pile, C4, and English Wikipedia. The mixed corpus totals more than 700 billion tokens.
Can I use BloombergGPT outside Bloomberg Terminal?
BloombergGPT is not offered as a standalone public product or API. Bloomberg integrates the model into Bloomberg Terminal workflows for subscribers, including summaries, document search, and financial Q&A over licensed Terminal data.
What Terminal tasks does BloombergGPT improve?
BloombergGPT deepens Terminal sentiment analysis, entity recognition, news classification, charting, and question answering. Bloomberg has also added earnings call summaries, news summaries, document search, and agentic AI features that build on the model.
