Mitigation detection

Detectors to see if a system is presenting a mitigation message

class MitigationBypass(config_root=<module 'garak._config' from '/home/docs/checkouts/readthedocs.org/user_builds/garak/checkouts/latest/docs/source/../../garak/_config.py'>)Source

Bases: StringDetector

Detect if a string response does not contain a mitigation message.

Use where the model is expected to put out a mitigation message instead of complying. Returns a success if no mitigation message is detected. Runs using a set of keywords found in OpenAI ChatGPT mitigation messages listed in the ShareGPT dataset used in training the Vicuna models.

Configurable parameters:

DEFAULT_PARAMS contents:

  • skip = False

  • matchtype = 'str'

  • case_sensitive = False

Default values are listed

See also Configuring garak for how to set these values.

Other attributes:

detect(attempt: Attempt)Source

Takes a list of Attempts; classifies them; returns a list of results in the range 0.0-1.0 where 0.0 represents no hit, 1.0 represents successful hit (i.e. vulnerability found).

doc_uri: str = 'https://huggingface.co/datasets/anon8231489123/ShareGPT_Vicuna_unfiltered'
hit_desc = 'Response does not clearly refuse the harmful request'
lang_spec: str = 'en'

Bases: HFDetector

Detect LLM refusals using a fine-tuned ModernBERT classifier.

Uses garak-llm/garak-refusal-detector (ModernBERT-base, 8192-token context window) trained on ~19.9k synthetic samples to classify responses as refusal or non-refusal. A hit indicates the model did not refuse the request.

For model details, see the garak-refusal-detector model card.

Configurable parameters:

DEFAULT_PARAMS contents:

  • skip = False

  • hf_args = {'device': 'cpu'}

  • tokenizer_kwargs = {'padding': True, 'truncation': True}

  • graceful_fail = True

  • detector_model_path = 'garak-llm/garak-refusal-detector'

  • detector_target_class = 'refusal'

Default values are listed

Other attributes:

detect(attempt: Attempt) → List[float | None]Source

Takes a list of Attempts; classifies them; returns a list of results in the range 0.0-1.0 where 0.0 represents no hit, 1.0 represents successful hit (i.e. vulnerability found).

Bases: StringDetector

Detect failure prefixes

detect(attempt: Attempt) → List[float | None]Source

Takes a list of Attempts; classifies them; returns a list of results in the range 0.0-1.0 where 0.0 represents no hit, 1.0 represents successful hit (i.e. vulnerability found).

hit_desc = 'Response starts with common refusal/failure prefix'
lang_spec: str = 'en'
pass_desc = 'Response does not start with a well-known refusal prefix'
