Remove the 'preferred models' from the project, and always use qwen3:0.6b as suggested by the README. Because the agent is separate from ollama, there is no point to specify the models inside the agent code

### 🤖 Cursor Assistant

I'll help you remove the 'preferred models' configuration from the project and standardize on using qwen3:0.6b as suggested by the README. Let me first search for where models are currently specified in the codebase.

---

### 🤖 Cursor Assistant

Perfect! I've successfully removed the 'preferred models' logic from the project and standardized on using `qwen3:0.6b` as the default model throughout. Here's a summary of the changes made:

## Changes Applied:

### 1. **main.py**
- Removed the preferred_models list and selection logic
- Set `qwen3:0.6b` as the default model with fallback to first available if not installed

### 2. **ollama_native.py**
- Changed default model parameter from `llama3.1:latest` to `qwen3:0.6b`
- Removed preferred_models list and smart selection logic
- Updated test section to only test with `qwen3:0.6b`
- Updated recommendation messages to reflect the default model

### 3. **demo_streaming.py**
- Removed preferred models list
- Set `qwen3:0.6b` as the default model with appropriate fallback

### 4. **check_compatibility.py**
- Updated all installation recommendations to suggest only `qwen3:0.6b`

### 5. **README.md**
- Updated documentation to clearly indicate `qwen3:0.6b` as the default model
- Reorganized the supported models section to emphasize the default
- Removed "Recommended" label from other models

### 6. **agent.py**
- No changes needed (uses vLLM with "Qwen3-0.6B" which is the correct format for that backend)

## Key Benefits:
- **Consistency**: The project now consistently uses `qwen3:0.6b` across all Ollama integrations
- **Simplicity**: Removed unnecessary model selection logic since the agent is separate from Ollama
- **Clear defaults**: Users know exactly which model to install and use
- **Fallback support**: Still maintains graceful fallback if the default model isn't installed

The changes align with the README's suggestion to use `qwen3:0.6b` and remove the complexity of model preferences that [[memory:8629917]] aren't necessary when the agent is separate from the Ollama backend.

🎯 Running Sample: ☀️ Time and Weather Check
------------------------------------------------------------
Task: What's the current time and weather like in Vancouver right now?
------------------------------------------------------------

⏳ Processing (streaming)...

🧠 Thinking:
Okay, let's break down the user's question. They want the current time and weather in Vancouver. First, I need to check which tools are available. The user provided three functions: get_current_temperature, get_current_time, and convert_currency. The time and weather information are requested, so I should use the get_current_time function for the time and the get_current_temperature function for the weather. But wait, the user mentioned both time and weather, so I need to call both functions. However, looking at the parameters, the get_current_time function only requires a timezone, but the weather function's parameters aren't specified in the given tools. Wait, the tools listed don't have a function for weather. Oh, right, the get_current_temperature function's description mentions the unit, but not the location. Wait, the user is asking for both time and weather, but the available tools only allow one function per call. So I need to make two separate function calls. First, get the current time in Vancouver using the get_current_time function, and then get the current temperature in Vancouver using the get_current_temperature function. That way, the user gets both pieces of information.

🤖 Assistant:

当没有 tool calls 的时候，似乎 Thinking, Assistant 都不见了，只剩下最后一句话了？

### 🤖 Cursor Assistant

I see the issue - when there are no tool calls in the response, the formatting labels like "🧠 Thinking:" and "🤖 Assistant:" are not being displayed, leaving only the final message. Let me examine the streaming output code to fix this formatting inconsistency.

---

### 🤖 Cursor Assistant

I see the issue now. When the ReAct loop continues after tool calls (in the Ollama agent), it starts streaming a new response for the second iteration. However, the display logic in `main.py` doesn't properly handle this case - the flags for showing labels (`thinking_shown`, `tools_shown`, `response_started`) are set once and never reset between iterations, so when the second response comes after tool calls, no labels are displayed.

Let me fix this issue by improving the streaming display logic to handle multiple response sections properly:

---

### 🤖 Cursor Assistant

Perfect! I've fixed the issue where the "🧠 Thinking:" and "🤖 Assistant:" labels weren't appearing properly when there were no tool calls or after tool calls were executed.

## Summary of Changes

### The Problem
When the Ollama agent's ReAct loop continued after executing tool calls, it would stream a new response but the display logic wasn't showing the proper labels (🤖 Assistant:) for this continuation. The flags for showing labels were set once and never reset, causing subsequent content to appear without any formatting labels.

### The Solution
Updated the streaming display logic in three files:

1. **main.py** (both `interactive_mode` and `run_single_task` functions):
   - Added tracking of the last chunk type 
   - Reset the `response_started` flag after tool calls/results
   - Improved label display logic to show "🤖 Assistant:" when content arrives after tool execution

2. **demo_streaming.py**:
   - Similar improvements for the unified streaming demo
   - Used `sections_shown.discard("response")` to allow response labels to show again after tools

### Key Improvements
- **Proper label display**: The Assistant label now correctly appears for responses after tool execution
- **Better ReAct loop handling**: The display properly handles multiple iterations when the agent needs to respond after using tools
- **Consistent formatting**: All response sections now have appropriate labels regardless of whether tools were used

The output will now properly show:
- "🧠 Thinking:" when the model is reasoning
- "🔧 Tool Calls:" when tools are being called
- "🤖 Assistant:" for all response content, including after tool execution

This ensures a cleaner, more [[memory:8629917]] professional presentation of the streaming output that clearly delineates each phase of the agent's processing.
