Removed a debugging `console.log` statement that was printing the `isCustom` variable and the model name. This statement was no longer necessary and was potentially causing issues.
The previous code used an empty string for the `apiKey` when no key was provided, which could lead to unexpected behavior. This commit replaces those with a temporary placeholder ("temp") to avoid potential errors and make the code more robust.
Adds support for OpenAI models, allowing users to leverage various OpenAI models directly from the application. This includes custom OpenAI models and OpenAI-specific configurations for seamless integration.
