What is the issue?

Seeing this strange think tag with medgemma1.5

Also can we have a think option for gemma just like on the aistudio? Thanks!

Relevant log output

ollama run medgemma1.5          
>>> hey
<unused94>thought
Thinking Process:

1.  **Identify the user's input:** The user simply typed "hey".
2.  **Interpret the input:** "Hey" is a common greeting. It's informal and friendly.
3.  **Determine the goal:** The user is initiating a conversation or just saying hello.
4.  **Formulate a response:**
    *   Acknowledge the greeting.
    *   Return the greeting.
    *   Offer assistance or invite further interaction.
5.  **Draft potential responses:**
    *   "Hey there!" (Simple, friendly)
    *   "Hi! How can I help you today?" (More direct, offers help)
    *   "Hello! What can I do for you?" (Slightly more formal)
    *   "Hey! How's it going?" (Friendly, conversational)
    *   "Hi! I'm here to help. What do you need?" (Clear, helpful)
6.  **Select the best response:** A combination of acknowledging the greeting and offering help seems appropriate 
for an AI assistant. "Hey there! How can I help you today?" or "Hi! What can I do for you?" are good options. 
Let's go with a slightly more conversational but still helpful tone.
7.  **Final Response Construction:** "Hey there! How can I help you today?" or "Hi! What can I help you with?" or 
"Hello! How may I assist you?" - The first one feels natural and friendly.<unused95>Hey there! How can I help you 
today?
