About

Astra for Law is an AI foundation for law firms and legal technology companies to build products and workflows around their expertise. It combines GPT-6 Astra with settings, tools, and context tailored for professional legal work, including a legal search index and instructions for legal analysis and writing. It can search U.S. case law, statutes, regulations, court rules, and administrative decisions across a corpus of more than 230 million URLs, with sources added daily. It is designed to find relevant authorities and passages, assess how relevant and binding they are, and apply that research to client facts, arguments, deal terms, and legal strategy. Custom instructions help distinguish court holdings from other observations, address authorities that weaken an argument, explain contractual risk, and identify uncertainty. Firms can customize workflows around their own precedents, methods, proprietary data, permitted sources, and review processes.

About

TILDE (Term Independent Likelihood moDEl) is a passage re-ranking and expansion framework built on BERT, designed to enhance retrieval performance by combining sparse term matching with deep contextual representations. The original TILDE model pre-computes term weights across the entire BERT vocabulary, which can lead to large index sizes. To address this, TILDEv2 introduces a more efficient approach by computing term weights only for terms present in expanded passages, resulting in indexes that are 99% smaller than those of the original TILDE. This efficiency is achieved by leveraging TILDE as a passage expansion model, where passages are expanded using top-k terms (e.g., top 200) to enrich their content. It provides scripts for indexing collections, re-ranking BM25 results, and training models using datasets like MS MARCO.
