Harvey Trains Open Source Models To Encode Law Firm Workflows

ModelsFeaturesIndustry

Harvey, an AI company focused on legal technology, is conducting Proof of Concept studies with law firms to train open source large language models on law firm workflows. CEO Winston Weinberg confirmed the initiative, which aims to encode complex legal processes into the models.

The studies involve training open source LLMs on workflows specific to law firms, potentially allowing the models to automate or assist in tasks such as document review and drafting. The use of open source models suggests a focus on customization and control over proprietary legal data.

If successful, the initiative could reduce costs and increase efficiency for law firms, but also raises questions about data privacy, model accuracy, and the impact on legal employment. Harvey has not disclosed which open source models are being used or the timeline for potential deployment.
