create a query engine in seconds

>>> from autollm import AutoQueryEngine, read_files_as_documents

>>> documents = read_files_as_documents(input_dir="path/to/documents")
>>> query_engine = AutoQueryEngine.from_defaults(documents)

>>> response = query_engine.query(
...     "Why did SafeVideo AI develop this project?"
... )

>>> response.response
"Because they wanted to deploy rag based llm apis in no time!"

🌟 features

supports 100+ LLMs

>>> from autollm import AutoQueryEngine

>>> os.environ["HUGGINGFACE_API_KEY"] = "huggingface_api_key"

>>> llm_model = "huggingface/WizardLM/WizardCoder-Python-34B-V1.0"
>>> llm_api_base = "https://my-endpoint.huggingface.cloud"

>>> AutoQueryEngine.from_defaults(
...     documents='...',
...     llm_model=llm_model,
...     llm_api_base=llm_api_base,
... )

👉 more llms:

huggingface - ollama example:

>>> from autollm import AutoQueryEngine

>>> llm_model = "ollama/llama2"
>>> llm_api_base = "http://localhost:11434"

>>> AutoQueryEngine.from_defaults(
...     documents='...',
...     llm_model=llm_model,
...     llm_api_base=llm_api_base,
... )

microsoft azure - openai example:

>>> from autollm import AutoQueryEngine

>>> os.environ["AZURE_API_KEY"] = ""
>>> os.environ["AZURE_API_BASE"] = ""
>>> os.environ["AZURE_API_VERSION"] = ""

>>> llm_model = "azure/<your_deployment_name>")

>>> AutoQueryEngine.from_defaults(

google - vertexai example:

>>> from autollm import AutoQueryEngine

>>> os.environ["VERTEXAI_PROJECT"] = "hardy-device-38811"  # Your Project ID`
>>> os.environ["VERTEXAI_LOCATION"] = "us-central1"  # Your Location

>>> llm_model = "text-bison@001"

supports 20+ VectorDBs

🌟Pro Tip: autollm defaults to lancedb as the vector store: it's setup-free, serverless, and 100x more cost-effective!

👉 more vectordbs:

QdrantVectorStore example:

>>> from autollm import AutoQueryEngine
>>> import qdrant_client

>>> vector_store_type = "QdrantVectorStore"
>>> client = qdrant_client.QdrantClient(
...     url="http://<host>:<port>",
...     api_key="<qdrant-api-key>"

...     collection_name=collection_name,
... )

automated cost calculation for 100+ LLMs

>>> from autollm import AutoServiceContext

>>> service_context = AutoServiceContext(enable_cost_calculation=True)

# Example verbose output after query
Embedding Token Usage: 7
LLM Prompt Token Usage: 1482
LLM Completion Token Usage: 47
LLM Total Token Cost: $0.002317

create FastAPI App in 1-Line

👉 example

>>> from autollm import AutoFastAPI

>>> app = AutoFastAPI.from_config(config_path, env_path)

Here, config and env should be replaced by your configuration and environment file paths.

After creating your FastAPI app, run the following command in your terminal to get it up and running:

uvicorn main:app

🔄 migration from llama-index

switching from Llama-Index? We've got you covered.

👉 easy migration

>>> from llama_index import StorageContext, ServiceContext, VectorStoreIndex
>>> from llama_index.vectorstores import LanceDBVectorStore

>>> from autollm import AutoQueryEngine

>>> vector_store = LanceDBVectorStore(uri="./.lancedb")
>>> storage_context = StorageContext.from_defaults(vector_store=vector_store)
>>> service_context = ServiceContext.from_defaults()
>>> index = VectorStoreIndex.from_documents(
        documents=documents,
        storage_context=storage_contex,
        service_context=service_context,
    )

>>> query_engine = AutoQueryEngine.from_instances(index)
