3DThe Gundam Base Vietnam – Awakening an Old Passion
A 3D designer revisits Gunpla at THE GUNDAM BASE POP-UP WORLD TOUR in Ho Chi Minh City. From part separation and joint mechanics to tooling, injection molding, and mass production, this article explores Gunpla as a remarkable example of industrial and 3D product design.
AI DevelopmentAI API Token Optimization: Cut Costs
A practical guide to AI API token optimization. See how conversation history, RAG documents, tool outputs and response length were reviewed to reduce input tokens from about 8,000 to 1,600 while preserving the information needed to answer users.
AI DevelopmentSEO in the Age of AI Search: Build a Knowledge System, Not Just More Articles
Publishing more articles does not automatically build authority. This guide explains how topical coverage, semantic SEO, original value, content cannibalisation management, internal links and site architecture work together to create a coherent knowledge system for AI-driven search.
AI DevelopmentTurning Google Colab into an API Server to Run Speech-to-Speech Voice AI
This PoC turns Google Colab into a temporary WebSocket server for speech-to-speech AI. It combines faster-whisper large-v3, Gemini 2.5 Flash-Lite, VOICEVOX and Silero VAD, then improves latency through sentence buffering, streaming responses and parallel TTS generation.
AI DevelopmentWhat We Learned Building Voice AI with Gemini: The Major Difference Between a PoC and a Commercial Service
A Gemini Live API PoC can deliver real-time voice conversations quickly, but production introduces concurrency, quotas, observability, model lifecycle and device-specific audio issues. This article explains why the architecture moved from direct browser access to LiveKit and Vertex AI.
Product DevelopmentGLB Texture Editor: Edit 3D Model Textures and Materials in Real Time in Your Browser
GLB Texture Editor is a browser-based tool for editing 3D model textures and materials in real time. Upload a GLB file, adjust base color, roughness, metalness, transparency, UV mapping, position, rotation, scale, and projection settings, then preview and export the updated model.
Digital TwinHigh-Performance Web BIM Viewer for Large IFC Models
This PoC converts large IFC models into optimized GLB files by BIM category for faster browser rendering. It demonstrates flexible layer controls, element data panels, smooth 3D navigation, and reduced z-fighting, while outlining a future automated IFC-to-GLB workflow.
AI DevelopmentWhat Is Function Calling? How AI Agents Work and How to Implement Them with LangGraph
Learn how Function Calling lets LLMs use external tools instead of performing every task themselves. This guide covers tool-use architecture, the evolution of coding agents, Structured Outputs, and a practical LangGraph and TypeScript implementation of the reasoning-and-action loop.
