Example Image1 ## 1. Get JieKou.AI Configuration Information ### (1) Register and Obtain an API Key Sign up for and log in to JieKou.AI. Enter the invitation code 【YGHNZ0】 during registration to receive a \$2 sign-up bonus. Example Image2 Open the 【API key】 management page, click the add button, enter a custom key name, and generate an API key. Example Image3 Example Image4 ### (2) Generate and Save the API Key !Note: Keys are encrypted and stored on the server. Once created, they cannot be viewed again. Please keep your key safe. If it is lost, you need to delete it in the console and create a new key. Example Image5 ### (3) Get the Model ID You Need to Use Find the model you want to use in the JieKou.AI Model Square, and copy the model ID and base URL. Example Image6 * Gemini-3-pro-preview * Gemini-2.5-pro * Claude-sonnet-4-5 * Gpt-5.1 * Gpt-4o For other model IDs, maximum context lengths, and pricing, see: [Model Square](https://jiekou.ai/models-console/library?auth_res=success\&is_reg=false) ## 2. Install DeepSearcher For the complete installation guide, see: [https://github.com/zilliztech/deep-searcher](https://github.com/zilliztech/deep-searcher) (1) Clone the repository ``` git clone https://github.com/zilliztech/deep-searcher.git cd deep-searcher ``` (2) Create a virtual environment and activate it ``` #MAKE SURE the python version is greater than or equal to 3.10 python3 -m venv .venv source .venv/bin/activate ``` (3) Install dependencies ``` pip install -e . ``` ## 3. Modify the Example Code to Connect to JieKou.AI Models The example code is located at `examples/basic_example.py`. You can use this example to run DeepSearcher. (1) Configure the API Key Set the API Key you just obtained in the local environment variable `JIEKOU_API_KEY`. ``` export JIEKOU_API_KEY="YOUR_JIEKOU_API_KEY" ``` (2) Configure the LLM and Embedding models Add the following code after the `config = Configuration()` line in the example code: ``` config.set_provider_config("llm", "JiekouAI", {"model": "claude-sonnet-4-5-20250929"}) config.set_provider_config("embedding", "JiekouAIEmbedding", {"model": "qwen/qwen3-embedding-8b"}) ``` (3) Configure the file path and prompt for retrieval Load a file from the specified local path and store its content in a collection. Modify the code where `load_from_local_files` is called. You can use the `examples/data/WhatisMilvus.pdf` file provided by the project, or use your own file. If you want to delete and recreate the collection during execution, set `force_new_collection` to `True`. ``` load_from_local_files( paths_or_directory=os.path.join(current_dir, "data/WhatisMilvus.pdf"), collection_name="milvus_docs", collection_description="All Milvus Documents", force_new_collection=True, # If you want to drop origin collection and create a new collection every time,set force_new_collection to True ) question="Write a report comparing Milvus with other vector databases." ``` (4) Run the example code from the project root directory: ``` python examples/basic_example.py ```
