Your AI can write sonnets, pass the bar exam and explain black holes. But ask it to clean up a messy folder? It might delete the wrong file and get stuck. That's why you need a harness – the system that tells AI models which tools to use, what to remember and how to recover when it screws up. The model race isn't over – it's just not the only race anymore. Same brains, wildly different results. That's the power of harness. While OpenAI, Anthropic and other developers provide end user-ready products, DeepSeek's approach is Lego‑style: every piece is a plugin. It's not a polished app – it's a box of parts. You don't just use it. You build your own. 📺 Subscribe to our YouTube channel and stay updated with our latest analysis and interviews:👇 https://www.youtube.com/channel/UCgrNz-aDmcr2uuto8_DL2jg 👈 Download our APP on Apple Store (iOS): https://itunes.apple.com/us/app/cctvnews-app/id922456579?l=zh&ls=1&mt=8 Download our APP on Google Play (Android): https://play.google.com/store/apps/details?id=com.imib.cctv For more: https://www.cgtn.com/video Most watched videos: Impossible Challenge: 30 seconds to count banknotes BLINDFOLDED https://www.youtube.com/watch?v=ZmP_Ybj-jws Impossible Challenge: Gymnastics Boy Arat Hosseini from Iran! https://www.youtube.com/watch?v=8sxX--U4c8w Impossible Challenge: How to calm babies in 5 seconds? https://www.youtube.com/watch?v=kR3q9sXM7WA
