Are open-source AI models free?

While the models themselves are often free, hosting them requires hardware and operational costs.

What are the advantages of open-source models?

They offer lower costs, data control, and customizable fine-tuning.

Should companies use open-source or closed-source models?

Most will ultimately use a combination of both: closed-source for capability and open-source for cost and control.

The Rise of Open-Source AI Models: How Llama and DeepSeek Are Changing the Landscape

Open-source models are rapidly catching up with their closed-source counterparts, giving companies the option to host their own AI solutions. What does this mean for Taiwan?

Open-Source Models Are No Longer Second Choices

In the past, open-source AI models were often considered "usable but not strong enough," but with the rapid progress of models like Llama, DeepSeek, and Qwen, the gap has narrowed significantly, making open-source a serious option.

Why Open-Source Matters

Cost: Hosting or using open-source model APIs can be much more cost-effective than closed-source alternatives.
Privacy and Control: Data can be kept in a self-hosted environment, which is particularly important for sensitive industries.
Customization: Models can be fine-tuned to create bespoke versions that fit specific needs.

How to Use Open-Source Models

Local deployment: Ollama, LM Studio, Jan.
Cloud inference: Together AI, Fireworks AI, Groq.
Model sources: Hugging Face.

Impact on Taiwan

SMBs: Can adopt AI at a lower cost without relying entirely on foreign closed-source services.
High-privacy industries (medical, legal, financial): Can keep data in a self-hosted environment.
Developers: Have more customizable and controllable options.

Things to Note

Open-source does not mean free — self-hosting requires hardware and maintenance capabilities; quality and security must also be self-monitored.

Future Trends

The landscape of "closed-source for capability, open-source for cost and control" will continue, with most companies eventually using a mix of both.

Conclusion

Open-source models give you the freedom to not be tied to a single service. When evaluating, consider not just capability, but also cost, privacy, and maintenance. For further reading: Using local AI to protect your data, 2026 comparison of mainstream AI large models.
