# Configure for Ollama
1. Install [Ollama](https://ollama.com). Make sure to review the system requirements before installation.
2. Install a language models in Ollama via terminal. For example, you can run:
For standard computers (minimum 8GB RAM):
```bash
ollama run qwen2.5-coder:7b
```
For better performance (16GB+ RAM):
```bash
ollama run qwen2.5-coder:14b
```
For high-end systems (32GB+ RAM):
```bash
ollama run qwen2.5-coder:32b
```
3. Open Qt Creator settings (Edit > Preferences on Linux/Windows, Qt Creator > Preferences on macOS)
4. Navigate to the "QodeAssist" tab
5. On the "General" page, verify:
- Ollama is selected as your LLM provider
- The URL is set to http://localhost:11434
- Your installed model appears in the model selection
- The prompt template is Ollama Auto FIM or Ollama Auto Chat for chat assistance. You can specify template if it is not work correct
- Disable using tools if your model doesn't support tooling
6. Click Apply if you made any changes
You're all set! QodeAssist is now ready to use in Qt Creator.
## Which models do I actually need?
You do **not** need a separate model for every agent. Each bundled Ollama agent
names a *default* model only as an example — you can point any agent at a model
you already have via its settings → **Change…** (a per-agent override; it does not
edit the bundled agent). **Seeing a model name on an agent is not a reason to
download it.**
The defaults cluster into a tiny set, so one or two pulls cover everyday use:
| Pull this | Unlocks |
|---|---|
| `qwen2.5-coder:7b` | Ollama Chat — Simple · Ollama Completion — FIM · Ollama Completion — Chat-style · Ollama Quick Refactor |
| `qwen3.5:9b` (or `:4b` on ~8 GB) | Ollama Chat — Thinking · Ollama Compression — 16/32 GB (`:4b` → Compression — 8 GB) |
Optional specialists — pull only if you want that capability:
| Pull this | For |
|---|---|
| `gemma4:12b` | Ollama Chat — Gemma 4 — agentic chat with vision + native reasoning |
| `theqtcompany/codellama-7b-qml` | Ollama Completion — QML (Qt) — Qt's QML-specific completion model |
Rule of thumb: pick the agent for the job, then either pull its named model **or**
swap it (Change…) for one you already have.
## Extended Thinking Mode
Ollama supports extended thinking mode for models that are capable of deep reasoning (such as DeepSeek-R1, QwQ, and similar reasoning models). This mode allows the model to show its step-by-step reasoning process before providing the final answer.
### How to Enable
**For Chat Assistant:**
1. Navigate to Qt Creator > Preferences > QodeAssist > Chat Assistant
2. In the "Extended Thinking (Claude, Ollama)" section, check "Enable extended thinking mode"
3. Select a reasoning-capable model (e.g., deepseek-r1:8b, qwq:32b)
4. Click Apply
**For Quick Refactoring:**
1. Navigate to Qt Creator > Preferences > QodeAssist > Quick Refactor
2. Check "Enable Thinking Mode"
3. Configure thinking budget and max tokens as needed
4. Click Apply
### Supported Models
Thinking mode works best with models specifically designed for reasoning:
- **DeepSeek-R1** series (deepseek-r1:8b, deepseek-r1:14b, deepseek-r1:32b)
- **QwQ** series (qwq:32b)
- Other models trained for chain-of-thought reasoning
### How It Works
When thinking mode is enabled:
1. The model generates internal reasoning (visible in the chat as "Thinking" blocks)
2. After reasoning, it provides the final answer
3. You can collapse/expand thinking blocks to focus on the final answer
4. Temperature is automatically set to 1.0 for optimal reasoning performance
**Technical Details:**
- Thinking mode adds the `enable_thinking: true` parameter to requests sent to Ollama
- This is natively supported by the Ollama API for compatible models
- Works in both Chat Assistant and Quick Refactoring contexts
