Example Image1 ## 1. Obtain Myrouter Configuration Information ### (1) Obtain an API Key Register and log in to Myrouter. Enter 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: The key is stored encrypted on the server and cannot be viewed again after creation. Please save your key securely. If lost, you will need to delete it from the console and create a new one. Example Image5 ### (3) Obtain the Model ID You Want to Use Find the desired model in the Myrouter Model Hub 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, refer to the [Model Hub](https://myrouter.ai/models-console/library?auth_res=success\&is_reg=false). ## 2. Install DeepSearcher For detailed installation instructions, refer to: [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 Myrouter 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 as a local environment variable `MYROUTER_API_KEY`. ``` export MYROUTER_API_KEY="Your Myrouter 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 paths and prompt for retrieval Load files from a specified local path and store their contents in a collection. Modify the code where `load_from_local_files` is called. You can use the project-provided `examples/data/WhatisMilvus.pdf` file or your own files. To delete and recreate the collection each time, 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 ```
