OpenGPA is an Open-source General Purpose Agent. A self-hosted solution boasting capabilities similar to popular GPTs.
- Agentic system with multi-step-reasoning, chain-of-thought, ReAct, tool use etc
- Support for all major LLMs such as LLama, Mistral, Anthropic, OpenAI, etc.
- Off-line first. You can run on your own box with a local LLM. Data won't leave the server. All the power of GPT without the data privacy nightmare.
- Extensible framework allows to plug your own actions, such as calling into internal services and APIs
- Simple UI exposing insight on the GPA internal reasoning and actions
- Built-in RAG to search internal document stores
- Free and open source, deploy anywhere, customize to your needs
OpenGPA is much more than a UI on top of a LLM. It implements an agentic workflow, where a LLM is used as the brain of an agent to reason through multiple steps of planning, reasoning, and tool use. In particular, OpenGpa is using the ReAct approach to verbally reason on the next step, decide on the action to execute, and observe the outcome.
{
"reasoning": "The user wants to know the current weather in Liege, Belgium.
The best action to get this information is to perform a web search with
the query 'current weather in Liege, Belgium'. The result of this action
will then be used to respond to the user's request.
This is not the final action as we have to get the results from the web
search first."
"action": {
"name": "webSearch",
"arguments": {
"query": "current weather in Liege, Belgium"
}
},
"is_final": false
}
Action selection is based on a catalog of action that can easily be extended through code. You could add an action to tap into an internal service to fetch some data, or a workflow engine to trigger a next step, etc.
The current version is a minimal POC yet, it already packs a few interesting pieces:
- Works with all LLM supported by spring-ai, including running LLama locally
- Multi-step task processing with chain-of-thought approach
- Action model with easy to extend actions for use by the agent
- Upload of artifacts to process by the agent
- Download of artifacts generated by the agent
- Import documents in knowledge base to support RAG search
Improve the Agentic capabilities:
- ✅ RAG enabling the agent to consult vast volume of internal documents
- Memory enabling the agent to remember key facts and use them later
- code generation and execution within the agent (using Groovy scripts?)
- remote API invocation to tap into existing enterprise APIs
- web interactions allowing the agent to navigate pages submit forms
- scheduled jobs for automating workflow
- triggers to create complete end-to-end workflows
Make OpenGPA enterprise ready:
- Persistence of tasks/steps
- Proper file storage and management
- User management and access control
- Secure API access through API gateway
- Auditing of task processing costs (token usage)
- Instrumentation and observability
If you are on a Mac, the following should be enough to get you started and running this locally. In case of trouble, please reach out on Discord.
Warning
Building requires Java 21. If you are on a Mac, you can easily install it
with brew install openjdk@21
By default, opengpa is using OpenAI gpt-4o as its LLM. Check the application.properties file
for configuration options and the spring-ai documentation to configure support for other LLMs.
mvn clean package -Pproduction
OPENAI_API_KEY=sk-*** java -jar opengpa-server/target/opengpa-server-0.2.0.jarOpen the UI on http://localhost:8000 and login with username opengpa and password opengpa.
For debugging purposes you can log all interactions and prompts using the following config:
opengpa.server.log-prompt=true
opengpa.server.log-folder=/tmp/opengpa/logs
