The past six months have witnessed a remarkable surge in the popularity, capability, and scalability of large language model (LLM) technology, with open-source model creators at the forefront of this evolution. Companies such as Meta and Alibaba Cloud have led these innovations, introducing models like Meta’s Llama 4 and Alibaba’s Qwen3.

This article focuses on the Qwen3 release, examining how it stacks up against earlier Qwen versions and other leading open-source LLMs. Additionally, it provides a comprehensive guide on deploying Qwen3 on NVIDIA GPU-powered DigitalOcean droplets.

Prerequisites

• Intermediate knowledge of Deep Learning, particularly LLM architectures and deployment.
• Familiarity with LLMs; a basic understanding will enhance comprehension.
• Basic Python skills, as the tutorial includes Python snippets for output generation.
• Access to a GPU droplet on DigitalOcean is necessary for this tutorial.

Overview of Qwen3

Qwen3 builds upon its predecessor from Alibaba Cloud, having undergone consistent updates since its first release. While a technical report is still pending for Qwen3, the model has inherited traits from its earlier iterations, including a Transformer-based decoder architecture and the Mixture of Experts technique, likely enhancing its functionality in this latest version.

The capabilities of Qwen3 have been highlighted in the official blog post by its developers, emphasizing features such as:

• The ability to switch between logical reasoning and general dialogue modes within a single model.
• Improved reasoning capabilities surpassing previous models, especially in tasks involving mathematics and commonsense reasoning.
• Enhanced alignment with human preferences, offering better performance in creative writing and interactive scenarios.
• Strong multilingual capabilities, supporting over 100 languages.

Comparisons with Other SOTA LLMs

Early assessments indicate that Qwen3, specifically the Qwn3-235B-A22 version, competes favorably with both open-source and closed-source models, such as DeepSeek-R1 and Gemini2.5-Pro. Further benchmarking is expected as more data on its performance becomes available.

Running Qwen3 on a GPU Droplet

To set up Qwen3 on DigitalOcean’s GPU Droplets, users can employ various tools including VLLM, SGLang, and Transformers. Here’s a brief overview of the setup process using the Qwen3-30B A3B model:

1. Launching a GPU Droplet: Start by deploying your DigitalOcean GPU droplet. You can follow detailed setup instructions for AI/ML environments on these droplets.

2. Setting Up the Environment: Access the terminal via SSH and install the necessary packages with the following commands:

   apt-get install git-lfs python3-pippip install vllm transformers sgl_kernel orjson torchaopip install --upgrade pippip install uvpip install "sglang[all]>=0.4.6.post2"

3. Downloading the Model: To obtain the model files, use:

   git-lfs clone https://huggingface.co/Qwen/Qwen3-30B-A3B

4. Using VLLM: To start serving the model with VLLM, execute:

   vllm serve ./Qwen3-30B-A3B --enable-reasoning --reasoning-parser deepseek_r1

   You can then query the model with cURL commands.

5. Using SGLang: Alternatively, start the model with:

   python3 -m sglang.launch_server --model-path ./Qwen3-30B-A3B --reasoning-parser qwen3

   Query using a similar cURL method as above.

6. Using Transformers: For direct interaction via Python, load the model with:

   from transformers import AutoModelForCausalLM, AutoTokenizermodel_name = "Qwen/Qwen3-30B-A3B"tokenizer = AutoTokenizer.from_pretrained(model_name)model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype="auto", device_map="auto")

   After preparing the model’s input, you can generate outputs using:

   generated_ids = model.generate(model_inputs, max_new_tokens=32768)

Conclusion

Qwen3 is a thrilling advancement in the LLM landscape, particularly with its unique ability to seamlessly navigate between logical reasoning and general dialogue. Its innovative capabilities signal a burgeoning era for models trained on sophisticated architectures.

The DigitalOcean community invites you to explore its offerings across compute, storage, networking, and managed databases, alongside this rich tutorial landscape to enhance your technical expertise.
