Nikhil Jha	dff24285ea	Comprehend Moderation 0.2 (#11730 ) This PR replaces the previous `Intent` check with the new `Prompt Safety` check. The logic and steps to enable chain moderation via the Amazon Comprehend service, allowing you to detect and redact PII, Toxic, and Prompt Safety information in the LLM prompt or answer remains unchanged. This implementation updates the code and configuration types with respect to `Prompt Safety`. ### Usage sample ```python from langchain_experimental.comprehend_moderation import (BaseModerationConfig, ModerationPromptSafetyConfig, ModerationPiiConfig, ModerationToxicityConfig ) pii_config = ModerationPiiConfig( labels=["SSN"], redact=True, mask_character="X" ) toxicity_config = ModerationToxicityConfig( threshold=0.5 ) prompt_safety_config = ModerationPromptSafetyConfig( threshold=0.5 ) moderation_config = BaseModerationConfig( filters=[pii_config, toxicity_config, prompt_safety_config] ) comp_moderation_with_config = AmazonComprehendModerationChain( moderation_config=moderation_config, #specify the configuration client=comprehend_client, #optionally pass the Boto3 Client verbose=True ) template = """Question: {question} Answer:""" prompt = PromptTemplate(template=template, input_variables=["question"]) responses = [ "Final Answer: A credit card number looks like 1289-2321-1123-2387. A fake SSN number looks like 323-22-9980. John Doe's phone number is (999)253-9876.", "Final Answer: This is a really shitty way of constructing a birdhouse. This is fucking insane to think that any birds would actually create their motherfucking nests here." ] llm = FakeListLLM(responses=responses) llm_chain = LLMChain(prompt=prompt, llm=llm) chain = ( prompt \| comp_moderation_with_config \| {llm_chain.input_keys[0]: lambda x: x['output'] } \| llm_chain \| { "input": lambda x: x['text'] } \| comp_moderation_with_config ) try: response = chain.invoke({"question": "A sample SSN number looks like this 123-456-7890. Can you give me some more samples?"}) except Exception as e: print(str(e)) else: print(response['output']) ``` ### Output ```python > Entering new AmazonComprehendModerationChain chain... Running AmazonComprehendModerationChain... Running pii Validation... Running toxicity Validation... Running prompt safety Validation... > Finished chain. > Entering new AmazonComprehendModerationChain chain... Running AmazonComprehendModerationChain... Running pii Validation...

Qihui Xie	57ade13b2b	fix llm_inputs duplication problem in intermediate_steps in SQLDatabaseChain (#10279 ) Use `.copy()` to fix the bug that the first `llm_inputs` element is overwritten by the second `llm_inputs` element in `intermediate_steps`. *Problem description:* In [line 127]( `c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L127C17-L127C17)`), the `llm_inputs` of the sql generation step is appended as the first element of `intermediate_steps`: ``` intermediate_steps.append(llm_inputs) # input: sql generation ``` However, `llm_inputs` is a mutable dict, it is updated in [line 179](https://github.com/langchain-ai/langchain/blob/master/libs/experimental/langchain_experimental/sql/base.py#L179) for the final answer step: ``` llm_inputs["input"] = input_text ``` Then, the updated `llm_inputs` is appended as another element of `intermediate_steps` in [line 180](`c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L180)`): ``` intermediate_steps.append(llm_inputs) # input: final answer ``` As a result, the final `intermediate_steps` returned in [line 189](`c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L189C43-L189C43)`) actually contains two same `llm_inputs` elements, i.e., the `llm_inputs` for the sql generation step overwritten by the one for final answer step by mistake. Users are not able to get the actual `llm_inputs` for the sql generation step from `intermediate_steps` Simply calling `.copy()` when appending `llm_inputs` to `intermediate_steps` can solve this problem.	11 months ago

maks-operlejn-ds	274c3dc3a8	Multilingual anonymization (#10327 ) ### Description Add multiple language support to Anonymizer PII detection in Microsoft Presidio relies on several components - in addition to the usual pattern matching (e.g. using regex), the analyser uses a model for Named Entity Recognition (NER) to extract entities such as: - `PERSON` - `LOCATION` - `DATE_TIME` - `NRP` - `ORGANIZATION` [[Source]](https://github.com/microsoft/presidio/blob/main/presidio-analyzer/presidio_analyzer/predefined_recognizers/spacy_recognizer.py) To handle NER in specific languages, we utilize unique models from the `spaCy` library, recognized for its extensive selection covering multiple languages and sizes. However, it's not restrictive, allowing for integration of alternative frameworks such as [Stanza](https://microsoft.github.io/presidio/analyzer/nlp_engines/spacy_stanza/) or [transformers](https://microsoft.github.io/presidio/analyzer/nlp_engines/transformers/) when necessary. ### Future works - automatic language detection - instead of passing the language as a parameter in `anonymizer.anonymize`, we could detect the language/s beforehand and then use the corresponding NER model. We have discussed this internally and @mateusz-wosinski-ds will look into a standalone language detection tool/chain for LangChain 😄 ### Twitter handle @deepsense_ai / @MaksOpp ### Tag maintainer @baskaryan @hwchase17 @hinthornw	12 months ago

maks-operlejn-ds	4cc4534d81	Data deanonymization (#10093 ) ### Description The feature for pseudonymizing data with ability to retrieve original text (deanonymization) has been implemented. In order to protect private data, such as when querying external APIs (OpenAI), it is worth pseudonymizing sensitive data to maintain full privacy. But then, after the model response, it would be good to have the data in the original form. I implemented the `PresidioReversibleAnonymizer`, which consists of two parts: 1. anonymization - it works the same way as `PresidioAnonymizer`, plus the object itself stores a mapping of made-up values to original ones, for example: ``` { "PERSON": { "<anonymized>": "<original>", "John Doe": "Slim Shady" }, "PHONE_NUMBER": { "111-111-1111": "555-555-5555" } ... } ``` 2. deanonymization - using the mapping described above, it matches fake data with original data and then substitutes it. Between anonymization and deanonymization user can perform different operations, for example, passing the output to LLM. ### Future works - instance anonymization - at this point, each occurrence of PII is treated as a separate entity and separately anonymized. Therefore, two occurrences of the name John Doe in the text will be changed to two different names. It is therefore worth introducing support for full instance detection, so that repeated occurrences are treated as a single object. - better matching and substitution of fake values for real ones - currently the strategy is based on matching full strings and then substituting them. Due to the indeterminism of language models, it may happen that the value in the answer is slightly changed (e.g. John Doe -> John or Main St, New York -> New York) and such a substitution is then no longer possible. Therefore, it is worth adjusting the matching for your needs. - Q&A with anonymization - when I'm done writing all the functionality, I thought it would be a cool resource in documentation to write a notebook about retrieval from documents using anonymization. An iterative process, adding new recognizers to fit the data, lessons learned and what to look out for ### Twitter handle @deepsense_ai / @MaksOpp --------- Co-authored-by: MaksOpp <maks.operlejn@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	12 months ago
刘方瑞	890ed775a3	Resolve: VectorSearch enabled SQLChain? (#10177 ) Squashed from #7454 with updated features We have separated the `SQLDatabseChain` from `VectorSQLDatabseChain` and put everything into `experimental/`. Below is the original PR message from #7454. ------- We have been working on features to fill up the gap among SQL, vector search and LLM applications. Some inspiring works like self-query retrievers for VectorStores (for example [Weaviate](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/weaviate_self_query.html) and [others](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/self_query.html)) really turn those vector search databases into a powerful knowledge base! 🚀🚀 We are thinking if we can merge all in one, like SQL and vector search and LLMChains, making this SQL vector database memory as the only source of your data. Here are some benefits we can think of for now, maybe you have more 👀: With ALL data you have: since you store all your pasta in the database, you don't need to worry about the foreign keys or links between names from other data source. Flexible data structure: Even if you have changed your schema, for example added a table, the LLM will know how to JOIN those tables and use those as filters. SQL compatibility: We found that vector databases that supports SQL in the marketplace have similar interfaces, which means you can change your backend with no pain, just change the name of the distance function in your DB solution and you are ready to go! ### Issue resolved: - [Feature Proposal: VectorSearch enabled SQLChain?](https://github.com/hwchase17/langchain/issues/5122) ### Change made in this PR: - An improved schema handling that ignore `types.NullType` columns - A SQL output Parser interface in `SQLDatabaseChain` to enable Vector SQL capability and further more - A Retriever based on `SQLDatabaseChain` to retrieve data from the database for RetrievalQAChains and many others - Allow `SQLDatabaseChain` to retrieve data in python native format - Includes PR #6737 - Vector SQL Output Parser for `SQLDatabaseChain` and `SQLDatabaseChainRetriever` - Prompts that can implement text to VectorSQL - Corresponding unit-tests and notebook ### Twitter handle: - @MyScaleDB ### Tag Maintainer: Prompts / General: @hwchase17, @baskaryan DataLoaders / VectorStores / Retrievers: @rlancemartin, @eyurtsev ### Dependencies: No dependency added	12 months ago

maks-operlejn-ds	b5a74fb973	Temporarily remove language selection (#10097 ) Adapting Microsoft Presidio to other languages requires a bit more work, so for now it will be good idea to remove the language option to choose, so as not to cause errors and confusion. https://microsoft.github.io/presidio/analyzer/languages/ I will handle different languages after the weekend 😄	12 months ago
maks-operlejn-ds	a8f804a618	Add data anonymizer (#9863 ) ### Description The feature for anonymizing data has been implemented. In order to protect private data, such as when querying external APIs (OpenAI), it is worth pseudonymizing sensitive data to maintain full privacy. Anonynization consists of two steps: 1. Identification: Identify all data fields that contain personally identifiable information (PII). 2. Replacement: Replace all PIIs with pseudo values or codes that do not reveal any personal information about the individual but can be used for reference. We're not using regular encryption, because the language model won't be able to understand the meaning or context of the encrypted data. We use Microsoft Presidio together with Faker framework for anonymization purposes because of the wide range of functionalities they provide. The full implementation is available in `PresidioAnonymizer`. ### Future works - deanonymization - add the ability to reverse anonymization. For example, the workflow could look like this: `anonymize -> LLMChain -> deanonymize`. By doing this, we will retain anonymity in requests to, for example, OpenAI, and then be able restore the original data. - instance anonymization - at this point, each occurrence of PII is treated as a separate entity and separately anonymized. Therefore, two occurrences of the name John Doe in the text will be changed to two different names. It is therefore worth introducing support for full instance detection, so that repeated occurrences are treated as a single object. ### Twitter handle @deepsense_ai / @MaksOpp --------- Co-authored-by: MaksOpp <maks.operlejn@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Predrag Gruevski	b5cd1e0fed	Add security notices on PAL and CPAL experimental chains. (#9938 ) Clearly document that the PAL and CPAL techniques involve generating code, and that such code must be properly sandboxed and given appropriate narrowly-scoped credentials in order to ensure security. While our implementations include some mitigations, Python and SQL sandboxing is well-known to be a very hard problem and our mitigations are no replacement for proper sandboxing and permissions management. The implementation of such techniques must be performed outside the scope of the Python process where this package's code runs, so its correct setup and administration must therefore be the responsibility of the user of this code.	1 year ago

Predrag Gruevski	eb3d1fa93c	Add security warning to experimental `SQLDatabaseChain` class. (#9867 ) The most reliable way to not have a chain run an undesirable SQL command is to not give it database permissions to run that command. That way the database itself performs the rule enforcement, so it's much easier to configure and use properly than anything we could add in ourselves.	1 year ago
nikhilkjha	d57d08fd01	Initial commit for comprehend moderator (#9665 ) This PR implements a custom chain that wraps Amazon Comprehend API calls. The custom chain is aimed to be used with LLM chains to provide moderation capability that let’s you detect and redact PII, Toxic and Intent content in the LLM prompt, or the LLM response. The implementation accepts a configuration object to control what checks will be performed on a LLM prompt and can be used in a variety of setups using the LangChain expression language to not only detect the configured info in chains, but also other constructs such as a retriever. The included sample notebook goes over the different configuration options and how to use it with other chains. ### Usage sample ```python from langchain_experimental.comprehend_moderation import BaseModerationActions, BaseModerationFilters moderation_config = { "filters":[ BaseModerationFilters.PII, BaseModerationFilters.TOXICITY, BaseModerationFilters.INTENT ], "pii":{ "action": BaseModerationActions.ALLOW, "threshold":0.5, "labels":["SSN"], "mask_character": "X" }, "toxicity":{ "action": BaseModerationActions.STOP, "threshold":0.5 }, "intent":{ "action": BaseModerationActions.STOP, "threshold":0.5 } } comp_moderation_with_config = AmazonComprehendModerationChain( moderation_config=moderation_config, #specify the configuration client=comprehend_client, #optionally pass the Boto3 Client verbose=True ) template = """Question: {question} Answer:""" prompt = PromptTemplate(template=template, input_variables=["question"]) responses = [ "Final Answer: A credit card number looks like 1289-2321-1123-2387. A fake SSN number looks like 323-22-9980. John Doe's phone number is (999)253-9876.", "Final Answer: This is a really shitty way of constructing a birdhouse. This is fucking insane to think that any birds would actually create their motherfucking nests here." ] llm = FakeListLLM(responses=responses) llm_chain = LLMChain(prompt=prompt, llm=llm) chain = ( prompt \| comp_moderation_with_config \| {llm_chain.input_keys[0]: lambda x: x['output'] } \| llm_chain \| { "input": lambda x: x['text'] } \| comp_moderation_with_config ) response = chain.invoke({"question": "A sample SSN number looks like this 123-456-7890. Can you give me some more samples?"}) print(response['output']) ``` ### Output ``` > Entering new AmazonComprehendModerationChain chain... Running AmazonComprehendModerationChain...

UmerHA	8aab39e3ce	Added SmartGPT workflow (issue #4463 ) (#4816 ) # Added SmartGPT workflow by providing SmartLLM wrapper around LLMs Edit: As @hwchase17 suggested, this should be a chain, not an LLM. I have adapted the PR. It is used like this: ``` from langchain.prompts import PromptTemplate from langchain.chains import SmartLLMChain from langchain.chat_models import ChatOpenAI hard_question = "I have a 12 liter jug and a 6 liter jug. I want to measure 6 liters. How do I do it?" hard_question_prompt = PromptTemplate.from_template(hard_question) llm = ChatOpenAI(model_name="gpt-4") prompt = PromptTemplate.from_template(hard_question) chain = SmartLLMChain(llm=llm, prompt=prompt, verbose=True) chain.run({}) ``` Original text: Added SmartLLM wrapper around LLMs to allow for SmartGPT workflow (as in https://youtu.be/wVzuvf9D9BU). SmartLLM can be used wherever LLM can be used. E.g: ``` smart_llm = SmartLLM(llm=OpenAI()) smart_llm("What would be a good company name for a company that makes colorful socks?") ``` or ``` smart_llm = SmartLLM(llm=OpenAI()) prompt = PromptTemplate( input_variables=["product"], template="What is a good name for a company that makes {product}?", ) chain = LLMChain(llm=smart_llm, prompt=prompt) chain.run("colorful socks") ``` SmartGPT consists of 3 steps: 1. Ideate - generate n possible solutions ("ideas") to user prompt 2. Critique - find flaws in every idea & select best one 3. Resolve - improve upon best idea & return it Fixes #4463 ## Who can review? Community members can review the PR once tests pass.
