Aozora Bank
On-premises Aozora LLM trained on internal data for questions on internal rules
Aozora Bank and neoAI trained an on-premises LLM on internal data and reported 130% of the earlier accuracy
Problem
Aozora Bank wanted a model that understood its internal terms and clerical rules for corporate and retail banking. Cloud API models did not meet its data security requirements.
Approach
Aozora Bank and neoAI built an on-premises platform on an open-source LLM. They continued its pretraining on the bank's internal data. The model was provisionally named Aozora LLM. It was tested on an internal benchmark that asks questions about clerical rules and uses retrieval over bank documents.
Results
Takeaway
The result comes from a benchmark the two companies built themselves. The release names no production launch date.
