### 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. |
