### 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 "βš™οΈ 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.
