🛠️ Installation

Prerequisite: Make sure Docker is installed and the Docker daemon is running.

Method 1: Docker (Recommended) New 🔥

For a containerized setup with Docker, follow the instructions in README.docker.md. This method uses Method A (helper script) to automate the process and provides an Admin UI for easy configuration.

Method 2: Local Setup

1. Clone the repository:

   git clone https://github.com/SPThole/CoexistAI.git coexistai
   cd coexistai
   

2. Configure your model and embedding settings:

   • [NEW] Edit config/model_config.json to set your preferred LLM and embedding model.
   • Edit above file to set your preferred SearxNG host and port (if needed)
   • Add LLM and Embedder API Key (for google mode both would be same)
   • Example (for full local mode):

{
  "llm_model_name": "jan-nano",
  "llm_type": "local",  // based on baseurl dict given below
  "embed_mode": "infinity_emb",
  "embedding_model_name": "nomic-ai/nomic-embed-text-v1",
  "llm_kwargs": {
    "temperature": 0.1,
    "max_tokens": null,
    "timeout": null,
    "max_retries": 2
  },
  "embed_kwargs": {},
  "llm_api_key": "dummy",
  "HOST_APP": "localhost",
  "PORT_NUM_APP": 8000,
  "HOST_SEARXNG": "localhost",
  "PORT_NUM_SEARXNG": 8080,
  "openai_compatible": {
    "google": "https://generativelanguage.googleapis.com/v1beta/openai/",
    "local": "http://localhost:1234/v1",
    "groq": "https://api.groq.com/openai/v1",
    "openai": "https://api.openai.com/v1",
    "others": "https://openrouter.ai/api/v1"
  }
}

• See the file for all available options and defaults.
• If you using others llm type, then check the openai_compatible url dict for others key, you can generally find it by "googling YOUR provider name openai api base compatilble url"

3. Run the setup script:

   • For macOS or Linux with zsh:

     zsh quick_setup.sh
     

   • For Linux with bash:

     bash quick_setup.sh
     

   The script will:

   • Pull the SearxNG Docker image
   • Create and activate a Python virtual environment
   • USER ACTION NEEDED Set your GOOGLE_API_KEY (edit the script to use your real key). Obtain your API key (Currently Gemini, OpenAI and ollama is supported) from your preferred LLM provider. (Only needed when google mode is set, else set in model_config.py)
   • Start the SearxNG Docker container
   • Install Python dependencies
   • Start the FastAPI server

4. That’s it!
   The FastAPI and MCP server will start automatically and you’re ready to go.

Note:

• Make sure Docker, Python 3, and pip are installed on your system.
• Edit quick_setup.sh to set your real GOOGLE_API_KEY before running (needed if using google models)
• Windows users can use WSL or Git Bash to run the script, or follow manual setup steps.

Get Your API Key (optional if you want to use gemini llm/google embedders)

Obtain your API key (Currently Gemini, OpenAI and ollama is supported) from your preferred LLM provider. Once you have the key, update the app.py file or your environment variables as follows:

import os
os.environ['GOOGLE_API_KEY'] = "YOUR_API_KEY"

Alternatively, you can set the API key in your shell before starting the server:

export YOUR_LLM_API_KEY=your-api-key-here

Note: For optimal quality and speed, use Google models with embedding-001 embeddings and Gemini Flash models. They provide free API keys.

Update the place (default: India) in utils/config.py for personalized results

🔧 How to use FASTAPI/tools

Remove comments after // before pasting Swagger UI: http://127.0.0.1:8000/docs if you haven't changed the host and port

1. Web Search

Search the web, summarize, and get actionable answers—automatically.

Endpoint:
POST /web-search

Request Example:

{
  "query": "Top news of today worldwide", // Query you want to ask; if you provide a URL and ask to summarise, it will summarize the full page.
  "rerank": true, // Set to true for better result ranking.
  "num_results": 2, // Number of top results per subquery to explore (higher values = more tokens, slower/more costly).
  "local_mode": false, // Set to true to explore local documents (currently, only PDF supported).
  "split": true, // Set to false if you want full pages as input to LLMs; false may cause slower/more costly response.
  "document_paths": [] // If local_mode is true, add a list of document paths, e.g., ["documents/1706.03762v7.pdf"]
}
