Finsight: adapting an open model for financial reasoning
October 2026 · Models released under Apache 2.0
Can exposing an open base model to financial filings, news and finance instructions improve its financial reasoning, within a small budget? We adapted Qwen3-14B-Base in two stages on a single AWS machine with eight NVIDIA A100 GPUs, in about a day: continued pretraining on roughly 330 million tokens of financial text, then fine-tuning on 191,428 finance instructions. Test sets were protected with 13-gram decontamination.
Numerical reasoning improved sharply. FinQA accuracy rose from 0.019 to 0.126, and multi-turn ConvFinQA from 0.148 to 0.203. But the average across six financial benchmarks fell from 0.441 to 0.399, mostly in sentiment analysis and named-entity recognition. Fine-tuning recovered part of what continued pretraining disturbed, without fully restoring it.
The final model runs in 4-bit on a 16 GB GPU, using about 9 GB of memory, so anyone can test it.
