There was a problem hiding this comment.
This is a conversion of the (to be deleted) file beam_search_test.py in the repo root. I can't run this, since our endpoints forbid key-based auth.

Ready for review, but I will need help running the notebook prior to merge. |

Description
Use the Lark grammar feature of the
OpenAIResponseTargetto create a beam search for PyRIT. This is a single turn attack, where a collection of candidate responses (the beams) are maintained. On each iteration, the model's response is allowed to extend a little for each beam. The beams are scored, with the worst performing ones discarded, and replaced with copies of higher scoring beams.Tests and Documentation
Have basic unit tests of the classes added, but since this requires features only currently in the
OpenAIResponseTargetthere didn't seem much point in mocking that. There is a notebook which runs everything E2E.
