Text to 3D World
The most viral feature of Opus 4.5 is its ability to generate interactive 3D scenes. You don't need to know Blender or Unity. Just ask: "Create a 3D model of a futuristic watch."
It writes the complex Three.js code, compiles it, and renders it directly in the chat window. You can rotate, zoom, and interact with the object immediately.
Current Session: Day 45
Context Retained: 100%
The "Forever" Chat
Context windows used to be a limitation. Opus 4.5 introduces Context Compaction.
It indexes your entire conversation history, compressing older memories but keeping them retrievable. You can have a single chat thread that lasts for years, and it will remember what you said on Day 1.
Agentic Workflows
Opus 4.5 is designed to work without you. It can take a high-level goal like "Plan a marketing campaign" and break it down into tasks.
1. Reading `Q4_Goals.pdf`...
2. Browsing competitor websites...
3. Drafting email campaign in Gmail...
4. Task Complete. Waiting for review.
