From the post
This was a one shot! I asked Claude Opus 5.5 to make a launch video for itself. It built everything out of just text. The sea, the planet, the title. Every frame is characters drawn in pure JavaScript! Even the soundtrack! One HTML file. No images, no video, no fonts, no audio files. All pure Javascript! Insanely impressed! The attention to detail is on another level! It even added its an easter egg all on its own! at the 20s mark the code seen on screen is part of the actual code it wrote to generate this exact video! Skill.md attached bellow. Try it yourself!
Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5. https://t.co/Q9C2VKQ79f
