## Summary

FinDialogLens is a hybrid LLM pipeline designed to extract events from multi-party financial chatrooms, specifically to identify missed trades. It uses compact fine-tuned classifiers as scaffolds to detect RFQ-triggers and price/trade outcome metadata, segments RFQ windows per event, and fills argument roles via a Trade Engine. With GPT-4o, it achieves 92.1% accuracy on final price and 94.3% on trade outcome, outperforming full-chatroom chain-of-thought prompting. Fine-tuned open-source LLMs as small as 3B parameters reach comparable performance with limited in-domain data. A difficulty-aware router reduces LLM calls by 85% on final price tasks while recovering half the accuracy gap to the GPT-4o version, saving over $300 per day at a scale of 70,000 RFQs daily.

## Key points

- FinDialogLens reaches 92.1% accuracy on final price and 94.3% on trade outcome using GPT-4o
- Fine-tuned open-source LLMs with as few as 3B parameters achieve comparable performance
- Difficulty-aware router cuts LLM calls by 85% on final price, saving over $300/day at 70,000 RFQ/day scale

## Why it matters

The system improves efficiency and reduces cost in financial trading workflows by automating missed-trade detection in complex, multi-party chat environments where manual recovery is infeasible.
