• App Attribution and Analytics : The App Attribution feature tracks app model usage and provides detailed analytics.
• Fusion : Achieve the same level of intelligence at less than half the price of Claude Fable 5 by having multiple cost-effective models answer in parallel and then merging and analyzing them using a judge model

How to use OpenRouter

• Register and log in : Visit the OpenRouter website https://openrouter.ai/, click the “Sign Up” button to register an account, and log in with your email and password.
• Obtain an API key : After logging in, go to the control panel, find the “API Keys” section, and create a new API key. The key is used for authentication and accessing OpenRouter’s API.
• Select a model : In the OpenRouter control panel, browse the available AI models and select the appropriate model according to your needs.
• Configuration Request : Configure request parameters according to the requirements of the selected model, including input text and model parameters (such as temperature, maximum length, etc.).
• Sending requests : Send requests via the API provided by OpenRouter. Use curlcommands, Python scripts, or other programming languages. For example, curla request using `openRouter.getRequest()` is shown below:

• Here is an example of a request using Python:

• Processing the response : Parse the model’s output response and apply the results to the application. The response is typically JSON formatted data containing the model’s output.
• Monitoring and Analysis : View model usage statistics in the OpenRouter control panel, including token usage and response time. Optimize model selection and request parameters based on these statistics to improve performance and reduce costs.
• Advanced features (optional) : Enhance application capabilities with advanced features such as presets, tool calling, real-time web search, and image/PDF processing.
