export SMART_LLM="gpt-4o" # The model use for others tasks in pipeline

Config env when run with Reasoning:

export R_MODEL=r1 # The model use for reasoning
export R_TEMPERATURE=0.2 # Config temperature for reasoning model
export R_REPORT_MODEL=gpt-4o # The model use for writing report
export R_PRESENCE_PENALTY=0 # Config presence_penalty for reasoning model

4. Configure and Run LiteLLM (Local LLM Server):

# Install LiteLLM
pip install litellm

# Create litellm_config.yaml file
cat > litellm_config.yaml << EOL
model_list:
  - model_name: text-embedding-3-large
    litellm_params:
      model: text-embedding-3-large
      api_key: ${OPENAI_API_KEY}
  - model_name: gpt-4o
    litellm_params:
      model: gpt-4o
      api_key: ${OPENAI_API_KEY}
  - model_name: o1-mini
    litellm_params:
      model: o1-mini
      api_key: ${OPENAI_API_KEY}
  - model_name: r1
    litellm_params:
      model: deepseek-reasoner
      api_base: https://api.deepseek.com/beta
      api_key: ${DEEPSEEK_API_KEY}

litellm_settings:
  drop_params: true
EOL

# Start LiteLLM server
litellm --config litellm_config.yaml

The LiteLLM server will run on http://localhost:4000 by default.

5. (Optional) Configure and Run LiteLLM with OpenRouter:

cat > litellm_config.yaml << EOL
model_list:
  - model_name: text-embedding-3-large

🖥️ Usage

Using the CLI

Run the deep search agent with your question:

There are two modes:

• Pipeline Mode: This mode is suitable for general questions and tasks.

python ii_researcher/cli.py --question "your question here"

• Reasoning Mode: This mode is suitable for complex questions and tasks.

python ii_researcher/cli.py --question "your question here" --use-reasoning --stream

Using MCP

1. Set up your environment variables

• Copy the .env.example file to create a new file named .env

  cp .env.example .env
  

• Edit the .env file and add your API keys and configure other settings:

2. Integrating with Claude You can integrate your MCP server with Claude using: Claude Desktop Integration
3. Install mcp to Claude

mcp install mcp/server.py -f .env

4. Restart your Claude App

Using the Web Interface

1. Install and Run Backend API (In case for frontend serving):

# Start the API server
python api.py

The API server will run on http://localhost:8000

2. Setup env for Frontend

Create a .env file in the frontend directory with the following content:

NEXT_PUBLIC_API_URL=http://localhost:8000

3. Install and Run Frontend:

# Navigate to frontend directory
cd frontend

# Install dependencies
npm install

# Start the development server
npm run dev

The frontend will be available at http://localhost:3000

🐳 Run with Docker

1. Important: Make sure you have set up all environment variables from step 3 before proceeding.

2. Start the services using Docker Compose:

# Build and start all services
docker compose up --build -d

The following services will be started:

• frontend: Next.js frontend application
• api: FastAPI backend service
• litellm: LiteLLM proxy server

The services will be available at:

• Frontend: http://localhost:3000
• Backend API: http://localhost:8000
• LiteLLM Server: http://localhost:4000

3. View logs:

# View all logs
docker compose logs -f

# View specific service logs
docker compose logs -f frontend
docker compose logs -f api
docker compose logs -f litellm

4. Stop the services:

docker compose down

🛠️ Running QwQ Model with SGLang

To run the Qwen/QwQ-32B model using SGLang, use the following command:

python3 -m sglang.launch_server --model-path Qwen/QwQ-32B --host 0.0.0.0 --port 30000 --tp 8 --context-length 131072
