Each word is represented by a unique vector in such a way that semantically similar words have similar vectors. 7 | * Popular word embedding methods include Word2Vec, GloVe, and FastText. 8 | * Word embeddings are essential in various NLP tasks such as sentiment analysis, machine translation, and named entity recognition. 9 | * They capture semantic relationships between words, allowing models to understand context and meaning. 10 | * In addition to words, entire sentences or paragraphs can be embedded into fixed-length vectors, preserving the semantic information of the text. 11 | * Sentence embeddings are useful for tasks like text classification, document clustering, and information retrieval 12 | 13 | ### Supported Embeddings: 14 | 15 | Currently we support one Embedding platforms , they are: 16 | 17 | * Langchain 18 | 19 | By default you can get a embedding function which is HuggingFace 20 | --------------------------------------------------------------------------------

Airbyte setup requires you to have _docker_, _docker compose_ and _git_ installed, hence its recommended to have those packages installed. 22 | 2. Clone the repository 23 | ```bash 24 | git clone https://github.com/airbytehq/airbyte.git 25 | ``` 26 | 3. Go into the cloned airbyte folder 27 | ```bash 28 | cd airbyte 29 | ``` 30 | 4. Run the following command in the same directory 31 | 32 | ```bash 33 | ./run-ab-platform.sh 34 | ``` 35 | 36 | 5. Now you should be able to access it at [http://localhost:8000](http://localhost:8000) 37 | 38 | **Note:** If you want to modify any configurations, you can edit it in _.env_ you get after your run it for the first time. 39 | 40 | Reference - [https://docs.airbyte.com/quickstart/deploy-airbyte/](https://docs.airbyte.com/quickstart/deploy-airbyte/) 41 | -------------------------------------------------------------------------------- /documentation/v0.1.0/components/vector-database/quickstart.md: -------------------------------------------------------------------------------- 1 | # 🔥 Quickstart 2 | 3 | For quickstart, you can rely on the default embedding option. By default we use "**HuggingFaceEmbedding**" This eliminates the need to configure embeddings, making the process effortless. 4 | 5 | To utilize the vectordb configuration with the default embedding: 6 | 7 | \=> **Vectordb usage with Retriever** 8 | 9 | ```python 10 | from genai_stack.vectordb.chroma import ChromaDB 11 | from genai_stack.retriever.langchain import LangChainRetriever 12 | vectordb = ChromaDB.from_kwargs(class_name = "genai-stack") 13 | retriever = LangChainRetriever.from_kwargs(vectordb = vectordb) 14 | retriever.retrieve("") 15 | 16 | # Output 17 | # 18 | ``` 19 | 20 | **=> Vectordb usage with ETL** 21 | 22 | ```python 23 | from genai_stack.vectordb.chroma import ChromaDB 24 | from genai_stack.etl.lang_loader import LangLoaderEtl 25 | from genai_stack.etl.utils import get_config_from_source_kwargs 26 | 27 | vectordb = ChromaDB.from_kwargs(class_name = "genai-stack") 28 | etl = LangLoaderEtl.from_kwargs(vectordb = vectordb, get_config_from_source_kwargs("pdf", "/path/to/pdf")) 29 | etl.run() 30 | ``` 31 | 32 | **Important Note:** A vector db is never used alone its used along with either ETL or Retrieval which gives a good usecase to use the vectordb. 33 | -------------------------------------------------------------------------------- /documentation/v0.1.0/getting-started/our-components/models-llms/custom-model.md: -------------------------------------------------------------------------------- 1 | # Custom Model 2 | 3 | A custom model can be created with few steps. 4 | 5 | 1. Import a `BaseModel`class from genai-stack. 6 | 2. Create a class with desired name(class name) and inherit the `BaseModel`class. 7 | 3. Implement two methods: 8 | * `load()` - Load the model. This method is run at once on class instantiation. 9 | 10 | Set a class attribute, which can be later accessed in the predict() method. This way a lot of time can be saved during prediction which avoids model loading during prediction. 11 | * `predict()`- Accept a parameter named `query`, which should hold the input to the model.\ 12 | Make prediction and return the generated prediction. 13 | 14 | #### Example 15 | 16 | Below code creates a GPT Neo model with GenAI Stack. 17 | 18 | ```python 19 | from genai_stack.model.base import BaseModel 20 | from transformers import pipeline 21 | 22 | class GptNeoModel(BaseModel): 23 | def load(self, model_path=None): 24 | # Set `pipeline` by creating a class attribute model i.e, self.model 25 | self.model = pipeline("text-generation", model="EleutherAI/gpt-neo-2.7B") 26 | 27 | def predict(self, query): 28 | response = self.model(query, max_length=50, do_sample=True, temperature=0.9) 29

We will cover vector stores in the vector store section. 40 | 41 | #### Run in a local environment 42 | 43 | Currently, we support the following models: 44 | 45 | * [GPT4all](../../assets/gpt4all.json) 46 | * [GPT3](../../assets/gpt3.json) 47 | 48 | Import the required model(Here we will use the gpt4all model) and initialize it and predict it. 49 | 50 | ```python 51 | from genai_stack.model import Gpt4AllModel 52 | 53 | llm = Gpt4AllModel.from_kwargs() 54 | model_response = llm.predict("How many countries are there in the world?") 55 | print(model_response["result"]) 56 | ``` 57 | 58 | If you directly used Python shell you will get the output if you're using a file to execute the file. 59 | 60 | ``` 61 | python3 62 | ``` 63 | 64 | ``` 65 | # Response from the above command 66 | There are currently 195 recognized independent states in the world. 67 | ``` 68 | 69 | Now you know how to use the GenAI Stack locally. 70 | -------------------------------------------------------------------------------- /documentation/v0.2.0/advanced-guide/openapi.md: -------------------------------------------------------------------------------- 1 | # 🔃 GenAI Server API's Reference 2 | 3 | Here are the API's for the core components of GenAI Stack Server. 4 | 5 | ##

Let's go ahead & test it. 51 | 52 | ### How to run LLM? 53 | 54 | Once the installation is complete you're good to go. 55 | 56 | **Note**: Here we will be running just an LLM model without any vector stores. We will cover vector stores in the vector store section. 57 | 58 | #### Run in a local environment 59 | 60 | Currently, we support the following models: 61 | 62 | * [GPT4all](../../assets/gpt4all.json) 63 | * [GPT3](../../assets/gpt3.json) 64 | 65 | Import the required model(Here we will use the gpt4all model) and initialize it and predict it. 66 | 67 | ```python 68 | from genai_stack.model import Gpt4AllModel 69 | 70 | llm = Gpt4AllModel.from_kwargs() 71 | model_response = llm.predict("How many countries are there in the world?") 72 | print(model_response["result"]) 73 | ``` 74 | 75 | If you directly used Python shell you will get the output if you're using a file to execute the file. 76 | 77 | ``` 78 | python3 79 | ``` 80 | 81 | ``` 82 | # Response from the above command 83 | There are currently 195 recognized independent states in the world. 84 | ``` 85 | 86 | Now you know how to use the GenAI Stack locally. 87 |

The purpose is to bridge the gap between raw data and actionable insights or responses that applications can utilize, leveraging the power of LLMs. 6 | 7 | ### How does it work? 8 | 9 | There are 4 main components involved in GenAI Stack. 10 | 11 | 1. Data extraction & loading 12 | 2. Vector databases 13 | 3. LLMs 14 | 4. Retrieval 15 | 16 | The operation of GenAI Stack can be understood through its various components: 17 | 18 | **Data extraction & loading:** 19 | 20 | Supports data extraction from various sources including structured (sql, postgress etc), unstructured (pdf, webpages etc) and semi-structured (mongoDB, documentDB etc) data sources. GenAI Stack supports airbyte and llamahub for this purpose. 21 | 22 | **Vector databases:** 23 | 24 | Data that has been extracted is then converted into vector embeddings. These embeddings are representations of the data in a format that can be quickly and accurately searched. Embeddings are stored in vector databases. GenAI Stack supports databases like weaviate and chromadb for this purpose. 25 | 26 | **LLMs:** 27 | 28 | Large Language Models leverage the vector embeddings to generate responses or insights based on user queries. We've pre-configured ChatGPT and gpt4all, however, you can configure your own custom models. With gpt4all and any other open source LLMs, it offers developers to host the entire stack and model on their own servers, providing them required privacy and security. 29 | 30 | **Retrieval:** 31 | 32 | LangChain is the default tool used for retrieving the best-suited embeddings based on the query. When a query is made, instead of searching through the raw data, GenAI Stack looks for the closest matching vector embedding. This ensures fast and accurate results. The overall mechanism ensures that the data is utilized in its entirety. When a query is made, the LLMs search through the closest embeddings, ensuring responses are generated without hallucination (i.e., without making things up or providing inaccurate information). 33 | 34 | In conclusion, GenAI Stack is a comprehensive framework that offers a structured approach to harness the capabilities of large language models for various applications. Its well-defined components ensure a smooth integration process, making it easier for developers to build applications powered by advanced LLMs. 35 | -------------------------------------------------------------------------------- /genai_stack/genai_server/services/vectordb_service.py: -------------------------------------------------------------------------------- 1 | from fastapi import HTTPException 2 | from sqlalchemy.orm import Session 3 | from genai_stack.genai_platform.services.base_service import BaseService 4 | from genai_stack.genai_server.models.vectordb_models import ( 5 | DocumentType, RetrieverAddDocumentsRequestModel, RetrieverSearchRequestModel, RetrieverAddDocumentsResponseModel, 6 | RetrieverSearchResponseModel 7 | ) 8 | from genai_stack.genai_server.schemas import StackSessionSchema 9 | from genai_stack.genai_server.utils import get_current_stack 10 | from genai_stack.genai_server.settings.config import stack_config 11 | 12 | 13 | class VectorDBService(BaseService): 14 | 15 | def add_documents(self, data: RetrieverAddDocumentsRequestModel) -> RetrieverAddDocumentsResponseModel: 16 | 17 | with Session(self.engine) as session: 18 | stack_session = session.get(StackSessionSchema, data.session_id) 19 | if stack_session is None: 20 | raise HTTPException(status_code=404, detail=f"Session {data.session_id} not found") 21 | stack = get_current_stack(config=stack_config, session=stack_session) 22 | stack.vectordb.add_documents(data.documents) 23 | return RetrieverAddDocumentsResponseModel( 24 | documents=[ 25 | DocumentType( 26 | page_content=document.page_content, 27 | metadata=document.metadata 28 | ) for document in data.documents 29 | ], 30 | session_id=data.session_id 31 | ) 32 | 33 | def search(self, data: RetrieverSearchRequestModel) -> RetrieverSearchResponseModel: 34 | 35 | with Session(self.engine) as session: 36 | stack_session = session.get(StackSessionSchema, data.session_id) 37 | stack = get_current_stack(config=stack_config, session=stack_session) 38 | if stack_session is None: 39 | raise HTTPException(status_code=404, detail=f"Session {data.session_id} not found") 40 | documents = stack.vectordb.search(data.query) 41 | return RetrieverSearchResponseModel( 42 | documents=[ 43 | DocumentType( 44 | page_content=document.page_content, 45 | metadata=document.metadata 46 | ) for document in documents 47 | ], 48 | session_id=data.session_id 49 | ) 50 | -------------------------------------------------------------------------------- /genai_stack/genai_store/sql_store.py: -------------------------------------------------------------------------------- 1 | from pydantic import BaseModel 2 | from typing import Optional 3 | from sqlalchemy.engine import Engine 4 | from sqlalchemy import create_engine 5 | from sqlalchemy.sql.schema import MetaData 6 | 7 | from genai_stack.genai_server.migrations.alembic import Alembic 8 | 9 | 10 | class SQLStoreConfiguration(BaseModel): 11 | """ 12 | Data Model for SQL Store Configurations. 13 | 14 | Args: 15 | url : The database path. 16 | meta_data : The meta_data object of schemas 17 | table_name : any table name from schemas, to check whether the database contains the tables or not. 18 | """ 19 | class Config: 20 | arbitrary_types_allowed = True 21 | 22 | url:str 23 | meta_data:MetaData 24 | table_name:str 25 | 26 | 27 | class SQLStore: 28 | """Store Implementation that uses SQL database backend.""" 29 | 30 | config:SQLStoreConfiguration 31 | config_class: SQLStoreConfiguration = SQLStoreConfiguration 32 | _engine: Optional[Engine] = None 33 | _alembic:Optional[Alembic] = None 34 | 35 | def __init__(self, url:str, meta_data:MetaData, table_name:str) -> None : 36 | 37 | self.config = self.config_class(url=url, meta_data=meta_data, table_name=table_name) 38 | self._initialise() 39 | 40 | @property 41 | def engine(self) -> Engine: 42 | """The SQLAlchemy engine. 43 | 44 | Returns: 45 | The SQLAlchemy engine. 46 | 47 | Raises: 48 | ValueError: If the store is not initialized. 49 | """ 50 | if not self._engine: 51 | raise ValueError("Store not initialized") 52 | return self._engine 53 | 54 | @property 55 | def alembic(self) -> None: 56 | """The Alembic wrapper. 57 | 58 | Returns: 59 | The Alembic wrapper. 60 | 61 | Raises: 62 | ValueError: If the store is not initialized. 63 | """ 64 | if not self._alembic: 65 | raise ValueError("Store not initialized") 66 | return self._alembic 67 | 68 | def _initialise(self) -> None: 69 | 70 | self._engine = create_engine(url=self.config.url) 71 | 72 | self._alembic = Alembic( 73 | database_uri=self.config.url, 74 | engine=self.engine, 75 | meta_data=self.config.meta_data, 76 | table_name=self.config.table_name 77 | ) 78 | 79 | self.migrate_database() 80 | 81 | def migrate_database(self): 82 | self.alembic.upgrade() --------------------------------------------------------------------------------
