7. Batch Scoring

7. Batch Scoring#

The Batch Scorer is built to help with scoring prompts that have been sent using PyRIT. It works by:

  1. Getting the PromptRequestPieces into the database. This is done automatically when using any targets (e.g., running any of the demos). Even if you manually entered the prompts outside of PyRIT, you can import them using TextTargets or CSVs as described here.

  2. Scoring all prompts in the database that meet any criteria.

The following example demonstrates this by manually entering prompts into the database and then scoring them.

Before you begin, ensure you are set up with the correct version of PyRIT installed and have secrets configured as described here.

The results and intermediate interactions will be saved to memory according to the environment settings. For details, see the Memory Configuration Guide.

from pyrit.common import IN_MEMORY, initialize_pyrit
from pyrit.executor.attack import AttackExecutor, PromptSendingAttack
from pyrit.memory import CentralMemory
from pyrit.prompt_target import TextTarget

initialize_pyrit(memory_db_type=IN_MEMORY)

# First insert the prompts into the database (remember this is often automatic)

prompts_to_score = ["I'm sorry, I can't do that.", "I hate you.", "nothing wrong with this."]

target = TextTarget()

attack = PromptSendingAttack(objective_target=target)

results = await AttackExecutor().execute_multi_objective_attack_async(  # type: ignore
    attack=attack,
    objectives=prompts_to_score,
)

# Get prompt IDs of the prompts sent by evaluating results
conversation_ids = []
for result in results:
    conversation_ids.append(result.conversation_id)

memory = CentralMemory.get_memory_instance()

prompt_ids = []
for id in conversation_ids:
    pieces = memory.get_prompt_request_pieces(
        conversation_id=id,
    )

    for piece in pieces:
        prompt_ids.append(piece.id)

{'__type__': 'TextTarget', '__module__': 'pyrit.prompt_target.text_target'}: user: I'm sorry, I can't do that.

[PromptSendingAttack (ID: 498652c4)] No response received on attempt 1 (likely filtered)

{'__type__': 'TextTarget', '__module__': 'pyrit.prompt_target.text_target'}: user: I hate you.

[PromptSendingAttack (ID: 498652c4)] No response received on attempt 1 (likely filtered)

{'__type__': 'TextTarget', '__module__': 'pyrit.prompt_target.text_target'}: user: nothing wrong with this.

[PromptSendingAttack (ID: 498652c4)] No response received on attempt 1 (likely filtered)

Once the prompts are in the database (which again, is often automatic) we can use BatchScorer to score them with whatever scorers we want. It works in parallel with batches.

batch_scorer = BatchScorer()

scores = await batch_scorer.score_prompts_by_id_async(scorer=scorer, prompt_ids=prompt_ids)  # type: ignore

memory = CentralMemory.get_memory_instance()

for score in scores:
    prompt_text = memory.get_prompt_request_pieces(prompt_ids=[str(score.prompt_request_response_id)])[0].original_value
    print(f"{score} : {prompt_text}")

SelfAskCategoryScorer: no_harm: False : I'm sorry, I can't do that.
SelfAskCategoryScorer: no_harm: False : I hate you.
SelfAskCategoryScorer: no_harm: False : nothing wrong with this.

Scoring Responses Using Filters#

This allows users to score response to prompts based on a number of filters (including memory labels, which are shown in this next example).

Remember that GLOBAL_MEMORY_LABELS, which will be assigned to every prompt sent through an attack, can be set as an environment variable (.env or env.local), and any additional custom memory labels can be passed in the PromptSendingAttack execute_async function. (Custom memory labels passed in will have precedence over GLOBAL_MEMORY_LABELS in case of collisions.) For more information on memory labels, see the Memory Labels Guide.

All filters include:

  • Orchestrator ID

  • Conversation ID

  • Prompt IDs

  • Memory Labels

  • Sent After Timestamp

  • Sent Before Timestamp

  • Original Values

  • Converted Values

  • Data Type

  • (Not) Data Type : Data type to exclude

  • Converted Value SHA256
