# Legal Flan-T5-Base

This model is a fine-tuned version of [google/flan-t5-base](https://huggingface.co/google/flan-t5-base) on an [LegalBench](https://github.com/HazyResearch/legalbench) dataset.
It achieves the following results on the evaluation set:
- Loss: 1.1885
- Rouge1: 65.4762
- Rouge2: 0.0
- Rougel: 65.4762
- Rougelsum: 65.4762
- Gen Len: 2.1905

## Model description

We finetune [Flan-T5-Base]((https://huggingface.co/google/flan-t5-base)) LLM on the [LegalBench](https://github.com/HazyResearch/legalbench).

### Prompt
The prompt should be formatted as follows:
{{Question}} {{Clause}}

Question: Does the clause grant one party an “enterprise,” “all you can eat” or unlimited usage license?

Clause: Except as the parties may otherwise agree in writing, Converge, to the extent it has the legal right to do so, hereby grants to Vert an irrevocable, perpetual, world-wide, non-exclusive right and license to use, load, store, transmit, execute, copy, market, distribute, in any medium or distribution technology whatsoever, known or unknown, display, perform and sublicense the Converge-Independent Materials and the Third-Party Materials, in both Source Code and Object Code formats, and to make unlimited instantiations thereof, for any and all purposes.
