TLDR - SaulLM-7B is a large language model (LLM) specifically designed to understand and generate legal text. It is based on the Mistral 7B LLM. SaulLM-7B was trained on a massive dataset of English legal documents (over 30 billion tokens). SaulLM-7B exhibits state-of-the-art proficiency in understanding and processing legal documents.

The Challenge:

  • The legal domain has been slow to fully benefit from the advancements in large language models (LLMs).

  • This is due to the unique challenges of legal text: specialized vocabulary, complex syntax, and the evolving nature of legal language.

The Solution - SaulLM-7B

  • The authors present SaulLM-7B, the first publicly available large language model specifically designed for the legal domain.

  • SaulLM-7B has 7 billion parameters and is trained on a massive dataset of legal text from various English-speaking jurisdictions.

  • This specialized training gives SaulLM-7B a superior understanding of legal language compared to generic LLMs.

Key Contributions:

  1. SaulLM-7B Family of Legal LLMs: The work introduces SaulLM-7B, along with an instruction-tuned variant, SaulLM-7B-Instruct. This variant is designed to excel at legal-specific tasks.

  2. LegalBench-Instruct Benchmark: The authors present LegalBench-Instruct, a new evaluation benchmark designed to measure the legal understanding of LLMs. It includes tasks from the MMLU benchmark further tailored to legal scenarios.

  3. Open Source Release: SaulLM-7B, SaulLM-7B-Instruct, and the evaluation code are all released under the MIT license. This encourages widespread adoption and collaboration in the legal AI field.

Innovations:

  • Specialized Training: SaulLM is trained on a massive legal corpus, ensuring it understands the complexities of legal language.

  • Instruction Tuning: SaulLM-7B-Instruct is fine-tuned to excel at specific legal tasks, outperforming generic counterparts.

  • Focused Benchmarking: LegalBench-Instruct allows better evaluation of LLMs designed for the legal domain.
