# Qwen 3 Agent Architectural spike.
|
||||
|
||||
This project demonstrates how to use the `qwen-agent` library to interact with a Qwen 3 language model, potentially leveraging MLX for local execution and incorporating tools like web search.
|
||||
|
||||
## Description
|
||||
|
||||
The core example (`agentic_search.py`) sets up an AI assistant powered by a specified Qwen 3 model (e.g., `qwen3:0.6B` running locally via Ollama). It showcases how to:
|
||||
* Configure the connection to the language model (local or API-based).
|
||||
* Define and integrate tools (like `code_interpreter` and MCP-based tools like DuckDuckGo search).
|
||||
* Run the agent with a user query and stream the responses.
|
||||
* Example prompt included - it was difficult to get the model with agents to also output the hyperlinks.
|
||||
|
||||
The smaller `try6b.py` is meant to test that qwen models work locally. 0.6B is a very small model, so easy to download, and was actually a a lot of fun to use.
|
||||
Event working with tools, when used with `agentic_search.py` worked, up to a point.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
* Python 3.13 or higher
|
||||
* `uv` package manager installed.
|
||||
* A running Qwen 3 model endpoint (like one served by Ollama at `http://localhost:11434`) or appropriate API keys if using a hosted service.
|
||||
* Optional: `mise` for managing development tools (like Node.js, though its specific use in this Python project isn't detailed in the provided context).
|
||||
|
||||
## Installation
|
||||
|
||||
1. **Clone the repository:**
|
||||
```bash
|
||||
git clone <your-repository-url>
|
||||
cd qwen3
|
||||
```
|
||||
|
||||
2. **Set up a virtual environment (recommended):**
|
||||
```bash
|
||||
# Using Python's built-in venv
|
||||
python -m venv .venv
|
||||
source .venv/bin/activate # On Windows use `.venv\Scripts\activate`
|
||||
|
||||
# Or using uv to create and activate
|
||||
uv venv .venv
|
||||
source .venv/bin/activate # On Windows use `.venv\Scripts\activate`
|
||||
```
|
||||
|
||||
3. **Install dependencies using `uv`:**
|
||||
The project dependencies are listed in `pyproject.toml`. Install the project and its dependencies:
|
||||
```bash
|
||||
uv pip install .
|
||||
```
|
||||
Alternatively, install dependencies directly from the list:
|
||||
```bash
|
||||
uv pip install mcp>=1.6.0 mlx>=0.25.1 mlx-lm>=0.24.0 python-dateutil>=2.9.0.post0 python-dotenv>=1.1.0 "qwen-agent[code-interpreter]>=0.0.20"
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
1. **Configure the LLM:**
|
||||
* Modify `agentic_search.py` to point to your Qwen 3 model endpoint or provide necessary API keys in the `llm_cfg` dictionary. The example is currently set up for a local Ollama endpoint.
|
||||
|
||||
2. **Run the agent script:**
|
||||
```bash
|
||||
python agentic_search.py
|
||||
```
|
||||
This will execute the predefined query in the script, run the agent, print progress dots (`.`) for each response chunk, and finally output the full structured response and the extracted content.
|
||||
|
||||
## Dependencies
|
||||
|
||||
Key Python libraries used:
|
||||
|
||||
* `qwen-agent`: For creating and managing the AI agent.
|
||||
* `mlx` / `mlx-lm`: Likely used for efficient model inference, especially on Apple Silicon.
|
||||
* `mcp`: For integrating external tools via the Multi-Agent Collaboration Protocol.
|
||||
* `python-dotenv`: For managing environment variables (e.g., API keys).
|
||||
|
||||
See `pyproject.toml` for the full list of dependencies.

---
|
||||
|
||||
### **2. Recent Trends (2024)**
|
||||
- **Transition Strategies**: Case studies and frameworks for migrating from monolithic to microservices architectures using DDD are prominent (e.g., *"Transition Strategies from Monolithic to Microservices Architectures: A Domain-Driven Approach"*).
|
||||
- **Value-Driven Analysis**: Research like *"Value-Driven Analysis and Design: Applying Domain-Driven Practices"* (2024) explores DDD's role in sustainability, ethics, and industrial applications.
|
||||
- **Tooling and Patterns**: Papers discuss the use of **domain-specific languages (DSLs)**, **context mapping**, and **bounded context modeling** to enhance DDD practices (e.g., *"Domain-Specific Language and Tools for Strategic Domain-Driven Design"*).
|
||||
|
||||
---
|
||||
|
||||
### **3. Foundational Work (2019–2024)**

|
||||
Okay, the user is asking about Domain-Driven Design (DDD) research from 2019 to 2024. Let me look through the provided references to see what's relevant.
|
||||
|
||||
First, I notice several papers from 2024. The Frontiers article mentions a reference architecture called Cybermycelium, which uses research-driven design. That's interesting because it combines DDD with existing frameworks. Another 2024 paper from Frontiers talks about value-driven analysis, which integrates ethical values into DDD. That's a newer angle, so I should highlight that.
|
||||
|
||||
There's a paper on Cybermycelium that references frameworks from 2008 and 2011, so it's building on existing research. The one about Value-Driven Analysis and Design (VDAD) outlines a process for ethical considerations, which is a practical application of DDD principles. That's a good point to mention.
|
||||
|
||||
The IJIREM article from 2024 discusses DDD bridging business requirements and object-oriented modeling. It also lists references from 2015, showing the evolution of DDD over time. The paper on cloud-native service architecture mentions integrating DDD for modular systems, which is relevant for modern applications.
|
||||
|
||||
There's a 2024 Springer article about automated domain model generation from user stories. That's a technical advancement in DDD, using machines to derive models. This could be a key point about current research trends.
|
||||
|
||||
Looking at the 2023 and 2022 papers, the Frontiers article on Cybermycelium was presented at a conference in 2023, so it's recent. The Springer paper on domain models from user stories is from 2025, but the user's range is up to 2024, so maybe that's a typo? Wait, the user specified up to 2024, so that 2025 paper might be out of scope. I should check the dates again. The user's query says "2019-2024," so the 2025 paper is outside. Maybe it's a mistake in the provided data. I'll note that but focus on the 2024 ones.
|
||||
|
||||
Also, the paper on "Value-Driven Analysis and Design" from 2024 is significant because it applies DDD to ethical values, which is a novel approach. The one about DDD in cloud-native architecture shows practical applications in modern tech.
|
||||
|
||||
I should summarize the key themes: integration with ethical considerations, automation in model creation, cloud-native applications, and research-driven frameworks. Also, mention the evolution from traditional DDD to these new approaches. Make sure to include the most recent and impactful studies from the list.

- **2024**: Research (e.g., *IJIREM*) underscores DDD's potential to address **social and ethical challenges** by embedding values into domain models, ensuring systems align with human-centric goals.
|
||||
|
||||
6. **Evolution of DDD Frameworks**
|
||||
- **2019–2024**: References to classic DDD concepts (e.g., bounded contexts, aggregates) persist, but newer works focus on:
|
||||
- Hybrid approaches (e.g., combining DDD with **AI/ML** for dynamic domain modeling).
|
||||
- Adaptation to **emerging domains** (e.g., IoT, blockchain).
