In the realm of payments and financial risk assessment, comprehending transactions is paramount.

The Complexity of Transaction Understanding

Transactions, in all their diversity, defy traditional, rule-based methodologies. Plaid, a trusted name in Open Banking, falls short with its subpar coverage of transaction data, coupled with occasionally misleading labels.

It remedies the limitations of its predecessor, SlopeGPT, by providing precise and succinct counterparty labels in an easily interpretable manner. The secret to its triumph lies in the creation of a specialized language during its training, honing in on the extraction of merchant names from transactions.

Harnessing the power of an efficient base model, OPT-125M, and a groundbreaking fine-tuning algorithm known as LoRA, TransFormer attains remarkable speed, capable of labeling over 500 transactions per second—an astounding 250x improvement over SlopeGPT. Its prowess is further exemplified by its impressive 72% exact match accuracy when compared to human experts, eclipsing Plaid’s performance, which lags behind at a mere 62%. With precision and unwavering consistency, TransFormer emerges as a dependable asset within any production system.
