New Model
For a long time, Meta's Llama series was the default choice for local AI. Qwen has changed the narrative. By training on a massive, diverse dataset including 29 languages and petabytes of code, it has become the "Developer's Choice" for building private, secure AI applications.
The "Qwen-Coder" Advantage
Qwen-Coder is a specialized variant that is terrifyingly good. It supports 92 programming languages.
Unlike generalist models that hallucinate libraries, Qwen-Coder was fine-tuned on GitHub repositories, StackOverflow, and documentation. It understands obscure error messages in Rust, optimizes SQL queries better than a DBA, and can refactor legacy COBOL code.
Benchmarks: Qwen vs. Llama vs. GPT-4
We ran the standard HumanEval (Python coding) and GSM8K (Math) benchmarks. The results speak for themselves.
| Metric | Qwen 2.5-72B | Llama 3.1-70B | GPT-4o (Closed) |
|---|---|---|---|
| HumanEval (Code) | 86.4% | 82.0% | 90.2% |
| GSM8K (Math) | 91.5% | 88.7% | 92.0% |
| Multilingual | Superior (29 langs) | Good (English focus) | Excellent |
| Context Window | 128k | 128k | 128k |
Run It Everywhere
Because Qwen is open-weights (Apache 2.0 license for smaller models), you can run it anywhere.
- Local Laptop: Run the quantized Qwen-7B or 14B on a MacBook Pro using Ollama or LM Studio.
- Private Cloud: Host the massive 72B model on AWS or Azure for complete data privacy (no data sent to OpenAI).
- Mobile: Qwen-1.5B is optimized to run natively on Android phones for on-device intelligence.
Pricing Plans
The model weights are free. You only pay for the compute (or use Alibaba Cloud's API).

Final Verdict
Qwen 2.5 is the new standard for open-source AI. If you are building a coding assistant, a math tutor, or a multi-lingual chatbot and want to avoid the high costs of OpenAI, Qwen is the model to beat.
