After carefully reading Kimi K3’s official technology blog, here are a few points that I think are great:

  • 3D Open World: Upgrading from writing code to delivering a runnable product This is not simply generating Three.js code. What K3 does is a complete game production process: * Plan the game world according to needs * Use Three.js + WebGPU + GPU Compute to implement rendering * Programmatically generate maps of forests, rivers, mountains, etc. * Call third-party 3D Asset tools to generate characters * Integrate weather, lighting, and animation * Finally output a browser game that can run
  • Chip Design: Agent begins to enter the EDA field. I think this Demo has the highest value. The official description is: 48 hours of continuous operation, independently completing chip design, optimization and verification. Use open source EDA tools to complete the RTL-to-verification process and end up with a working chip design. Agent can complete long-term projects. The entire process includes: Understanding the goal Architecture design Calling EDA Timing Closure Verification Multiple rounds of optimization
  • Video Editing: Multi-modal Agent begins to replace the creative workflow An official example: Generate a video similar to 3Blue1Brown style. Technical content ↓ Disassembly script ↓ Animation design ↓ Lens ↓ Transition ↓ Output video The K3 model can serve as a long-running engineering agent to continuously execute complex workflows across multiple professional fields. Like Kimi👍 It should be called "Hakimi", haha
