BloombergGPT: The Finance NLP Benchmark

What it is: A 50-billion parameter language model trained by Bloomberg on 40+ years of financial data. Released in 2023 as a research paper, not a commercial product.

Strengths:

• State-of-the-art on financial NLP benchmarks
• Trained on massive proprietary Bloomberg Terminal data
• Excellent for sentiment analysis, NER, and document understanding

Limitations:

• Not publicly available for use or fine-tuning
• Estimated $3M+ to replicate the training data
• Focused on understanding finance, not executing transactions
• No decision data, reasoning traces, or trading episodes

Best for: Financial NLP research, if you can get access. Benchmark reference for the field.

FinGPT: The Open Source Option

What it is: An open-source framework for financial LLMs from AI4Finance. Provides fine-tuning pipelines and curated datasets.

Strengths:

• Completely open source and free
• Active community and regular updates
• Good starting point for experimentation
• Includes sentiment datasets and news data

Limitations:

• Text-only: no decision episodes or trading data
• No reasoning traces or process supervision
• Can teach models to talk about finance, not trade
• Quality varies across datasets

Best for: Academic research, experimentation, financial NLP tasks where budget is limited.

Scale AI: The Labeling Platform

What it is: A data labeling platform that can create custom datasets for any domain, including finance. Known for high-quality human annotations.

Strengths:

• Can create any custom data structure
• High-quality human labeling at scale
• Experience with RLHF data for frontier labs
• Flexible to specific requirements

Limitations:

• Not specialized in financial decisions
• You need to design the data structure yourself
• No pre-built financial AI datasets
• Labelers may lack trading expertise
• Custom projects can be expensive

Best for: Teams with clear data requirements and budget for custom annotation projects.

UV Labs: Decision Episode Data

What it is: Purpose-built training data for AI that transacts. Decision episodes with complete reasoning traces, verified outcomes, and counterfactual analysis.

Strengths:

• Only provider of complete decision episodes
• Reasoning traces enable process supervision
• Counterfactuals multiply learning signal
• Replayable RL environment included
• Built specifically for financial AI training

Limitations:

• Not focused on general financial NLP
• Smaller scale than pre-training datasets
• Commercial product, not open source

Best for: Teams building AI that needs to make and execute financial decisions, not just analyze text.

Which Should You Choose?

The Core Difference

Most financial AI training data teaches models to talk about finance. UV Labs teaches models to do finance.

BloombergGPT knows what a margin call is. FinGPT can summarize earnings reports. These are valuable capabilities.

But they don't teach a model when to take profit, how to size a position relative to conviction, or what to do when a trade goes against you. That requires decision data: complete episodes showing how expert agents think and act under uncertainty.

If your goal is building AI that transacts, you need training data that captures transactions.
