Opus 5.5 calls Grok to run much better than native open source. However
Opus 5.5 calls Grok to run much better than native open source. However, a 5-minute MTV consumes my weekly grok quota of a premium+ and a premium X account, and I have not finished producing the footage.
Anthropic released Sonnet 5.5 on September 28. The price remains unchanged: input $2, output $10/million tokens.
Official: To do the same work, tokens are much less, and each task is up to 30% cheaper; Terminal-Bench is 70.6%, exceeding Opus 5.5’s 66.4%. Third-party Artificial Analysis: At the highest level, each question costs about 193,000 tokens and $7.6, which is about half more expensive than Sonnet 5.
I asked Claude Code Opus 5.5 to make a video about itself.
This is what it made. Absolutely insane! It wrote the song, then drew all 7,118 frames in code. No After Effects. Opus handled the Motion graphics, kinetic type, and a figure made of light. "I am OPUS 5" · Sound On!
