Data processing with ML, LLM and Vision LLM
Sparrow is an innovative open-source solution for efficient data extraction and processing from various documents and images. It seamlessly handles forms, bank statements, invoices, receipts, and other unstructured data sources. Sparrow stands out with its modular architecture, offering independent services and agents all optimized for robust performance. One of the critical functionalities of Sparrow - pluggable architecture. You can easily integrate and run data extraction pipelines using Sparrow Parse (with vision-language models support) or Instructor. Sparrow enables local LLM data extraction pipelines through various backends, such as vLLM, Ollama, PyTorch or Apple MLX. Sparrow Parse with VL model can run either on premise, or it can execute inference on cloud GPU. With Sparrow solution you get API, which helps to process and transform your data into structured output, ready to be integrated with custom workflows.
Sparrow Agents - with Sparrow you can build independent LLM agents, and use API to invoke them from your system.
- Sparrow ML LLM - Sparrow main engine that runs various agents
- Sparrow Parse - Sparrow library enabling Sparrow Parse agent functionality using VL LLM. Works great for structured JSON response generation
- Sparrow OCR - OCR service, providing optical character recognition
- Sparrow UI - Dashboard UI for Sparrow

}- Install
pyenvand then install Python into your environment - Create virtual environment for the Sparrow agent you want to run
- Install requirements for the Sparrow agent you want to use. Keep in mind, depending on OS, it could be required to do additional install steps for some of the libraries (for example PaddleOCR)
- Run Sparrow either from CLI or from API. You need to start API endpoint
- Pass query in the form of JSON schema to extract data from the document
See detailed instructions below.
- Python environment
For more details, check out the extended section.
- Run Sparrow
You can run Sparrow on CLI or through API. To run on CLI, use sparrow.sh script. Run it from corresponding virtual environment, depending which agent you want to execute. sparrow-parse agent is using VL LLM model. sparrow-parse agent runs VL LLM either locally with MLX, Ollama, or using cloud GPU. instructor agent is using Ollama backend. Make sure to pull LLM model for Ollama using name specified in config.yml to run instructor agent.
- Private deployment
There is a property PROTECTED_ACCESS: False in config.yml. When set to False, sparrow_key is not verified on API call. Otherwise correct sparrow-key needs to be provided for API call.
You can use these options:
--options mlx - this will set MLX as backend for local inference
--options mlx-community/Qwen2-VL-72B-Instruct-4bit - name for Vision LLM model, supported by MLX
--options tables_only - set this option, if you want to process tables only
--options validation_off - set this option, if you want to disable response validation
First two options are always set first.
✅ Sparrow Parse agent, running locally with Apple MLX backend.
Sparrow validates response against request schema. Result of validation is automatically included into response, see property valid.

}✅ Sparrow Parse agent, with GPU backend on Hugging Face. GPU backend katanaml/sparrow-qwen2-vl-7b is private, to be able to run below command, you need to create your own backend on Hugging Face space using code from Sparrow Parse.
./sparrow.sh "[{"instrument_name":"str", "valuation":0}]" --agent "sparrow-parse" --debug --options huggingface --options katanaml/sparrow-qwen2-vl-7b --file-path "/data/bonds_table.png"
✅ Sparrow Parse agent supports multi-page PDF documents. Running locally with Apple MLX backend. Response will be structured per page with page number indicators.

Example running private GPU backend katanaml/sparrow-qwen2-vl-7b:
./sparrow.sh "{"table": [{"description": "str", "latest_amount": 0, "previous_amount": 0}]}" --agent "sparrow-parse" --debug --options huggingface --options katanaml/sparrow-qwen2-vl-7b --file-path "/data/oracle_10k_2014_q1_small.pdf" --debug-dir "/data/"

Sparrow enables you to run a local LLM RAG as an API using FastAPI, providing a convenient and efficient way to interact with our services. You can pass the name of the plugin to be used for the inference. By default, sparrow-parse agent is used.
To set this up:
- Start the Endpoint
Launch the endpoint by executing the following command in your terminal:
python api.py
If you want to run agents from different Python virtual environments simultaneously, you can specify port, to avoid conflicts:
python api.py --port 8001
- Access the Endpoint Documentation
You can view detailed documentation for the API by navigating to:
http://127.0.0.1:8000/api/v1/sparrow-llm/docs
For visual reference, a screenshot of the FastAPI endpoint
You can use these options:
mlx - this will set MLX as backend for local inference
mlx-community/Qwen2-VL-72B-Instruct-4bit - name for Vision LLM model, supported by MLX
tables_only - set this option, if you want to process tables only
validation_off - set this option, if you want to disable response validation
First two options are always set first.
✅ sparrow-parse agent. This agent runs locally with Apple MLX backend.
curl -X 'POST' \
'http://127.0.0.1:8000/api/v1/sparrow-llm/inference' \
-H 'accept: application/json' \
-H 'Content-Type: multipart/form-data' \
-F 'query=[{"instrument_name":"str","valuation":0}]' \
-F 'agent=sparrow-parse' \

-F 'debug=false' \
-F 'sparrow_key=' \
-F 'file=@bonds_table.png;type=image/png'
Alternatively, agent can run Visual LLM with GPU backend on Hugging Face. GPU backend katanaml/sparrow-qwen2-vl-7b is private, to be able to run below command, you need to create your own backend on Hugging Face space using code from Sparrow Parse.
curl -X 'POST' \
'http://127.0.0.1:8000/api/v1/sparrow-llm/inference' \
-H 'accept: application/json' \
-H 'Content-Type: multipart/form-data' \
-F 'query=[{"instrument_name":"str","valuation":0}]' \
-F 'agent=sparrow-parse' \
-F 'options=huggingface,katanaml/sparrow-qwen2-vl-7b' \
-F 'debug=false' \
-F 'sparrow_key=' \
-F 'file=@bonds_table.png;type=image/png'
Sparrow Parse agent supports multi-page PDF documents. You can pass PDF document through the API endpoint, response will be structured per page with page number indicators:
