AI Harness Explained — What Happens When It Becomes Open Source? (拆解 AI Harness — 當它走向開源，會帶來甚麼改變？)

​When we talk about AI, most of the attention goes to the model. But a powerful model alone does not make an AI system useful.

​Behind many capable AI products is another important layer: the AI harness—the surrounding system that helps a model manage context, use tools, interact with systems and complete complex tasks.

​With OpenAI opening up the Codex harness and DeepSeek releasing its open-source DeepSeek Harness in August 2026, this important layer beyond the model is becoming increasingly accessible. What could this change for businesses?

​In this online sharing session, Emprise Chan, AI Strategy Consultant at Ultermind, will explore four key questions:

• ​What is an AI harness, and how is it different from a model or agent?

• ​Why can the same model perform very differently depending on the harness around it?

• ​What changes when capable AI harnesses become open source?

• ​How could this reshape the buy vs. build decision for businesses?

​By the end of the session, you should have a clearer understanding of the layer beyond the AI model—and why the rise of open-source harnesses could influence how businesses design, buy and build AI systems.

​This session is designed for business owners, managers and decision-makers who want to understand where enterprise AI is heading, without needing a deep technical background.
