Pull Request: Adding New Experimental Models

Overview

This pull request introduces a set of new experimental models to be integrated into the project. The models are listed below:

Model Name	Description	Status
gemini-2.0-flash-exp	A state-of-the-art model that emphasizes on flash performance.	Development
gemini-2.0-flash-thinking-exp-1219	An enhanced version of gemini-2.0-flash-exp with additional thinking capabilities.	Development
learnlm-1.5-pro-experimental	An advanced learning model with experimental features to improve its professional capabilities.	Development

Purpose

• gemini-2.0-flash-exp aims to improve the performance of existing systems by leveraging the latest flash technologies.
• gemini-2.0-flash-thinking-exp-1219 takes the gemini-2.0-flash-exp model to the next level, integrating thinking capabilities to ensure better decision-making in real-time environments.
• learnlm-1.5-pro-experimental is designed to enhance the system's learning abilities with an advanced set of features, making it more versatile and adaptable to a wider range of applications.
