A user asked Opus 5.5 for a guitar riff and it ended up "forming a band": a complete music video, "The Context Windows", produced 100% locally on a single MacBook in 24 hours.
The stack: Blender + Python scripts for 3D modeling and video editing, Qwen-Image 2.1 for images, music composed from GarageBand instruments (Claude reverse-engineered the file format), and vocals from the open SoulX-Singer model running via MLX. The characters' fretting and strumming in the video are physically accurate.
The author argues the 5.5 series marks a huge creativity breakthrough at Anthropic, with no other model coming close.
