VCs Highlight Open-Source Models in Legal and Finance AI
Replies note Harvey and Cfosilvia fine-tuning open-source models for legal and finance tasks.
Gavin Baker replied to David Sacks that the Poolside news signals the future of American open-source. He noted Harvey's use of the open-source Kimi K3 model after post-training on legal data. Anthony Pompliano replied that his firm Cfosilvia follows a similar path. He stated this approach explains its lead in frontier models for the finance category. Both comments address specialized AI built from open-source foundations. The posts form part of the visible conversation around the original thread.
@DavidSacks @sarthakgh Yes. Although I do think the Poolside news is an important indicator for the future of American open-source.

2 posts@DavidSacks This is a similar approach that we are taking at @cfosilvia and is a big reason why we have dominated the frontier models in finance category.
The terminology here can be misleading. AFAIK Moonshot released only the post-trained Kimi K3 checkpoint, not a separate pretrain-only base model. I assume Harvey did further post-train on the open-weighted Kimi K3 post-trained model.
Harvey is a great example of how American companies are building world-class specialized models: they took an open-source base (Kimi K3), post-trained it on legal data, and delivered state-of-the-art performance on legal benchmarks at a fraction of the cost of frontier models.…
