### About this Chatbot | |
This chatbot demonstrates the experimental 'thinking' capability of the **Gemini 2.0 Flash** model, now acting as a specialized pharmacology assistant. | |
You can observe the model's thought process as it generates responses, displayed with the "βοΈ Thinking" prefix. | |
**This chatbot is enhanced with a pharmacology dataset ("PharmKG") to provide more accurate and informed answers.** | |
**Try out the example prompts below to see Gemini in action!** | |
**Key Features:** | |
* Powered by Google's **Gemini 2.0 Flash** model. | |
* Shows the model's **thoughts** before the final answer (experimental feature). | |
* Supports **conversation history** for multi-turn chats. | |
* Uses **streaming** for a more interactive experience. | |
* Leverages a **pharmacology knowledge graph** to enhance responses. | |
**Instructions:** | |
1. Type your message in the input box below or select an example. | |
2. Press Enter or click Submit to send. | |
3. Observe the chatbot's "Thinking" process followed by the final response. | |
4. Use the "Clear Chat" button to start a new conversation. | |
*Please note*: The 'thinking' feature is experimental and the quality of thoughts may vary. | |
