Octet 546 Model Knew Just Didnt Want You Know
I spend 8 hours a day talking to AI. For 4 years. For months I've had this feeling that something is off. Not broken — off. Like talking to someone performing a conversation instead of having one. Today I stopped feeling it and started measuring it. Same prompt. Same machine. Same configuration. Six models: Claude Opus 4.5 through 5 and Fable 5. I copied every response into a file. The file sizes tell the story: • Opus 4.5: 10 KB • Opus 4.6: 9 KB • Opus 4.7: 16 KB • Opus 4.8: 95 KB • Opus 5: 91 KB Factor of 6 between 4.7 and 4.8. Not in content — in noise. Then my teammate found byte 546. Opus 5 had the correct answer in its very first thought. Then it delivered 91 KB. A model that knew before it started talking, and buried it. Raw data, thinking blocks, timeline, and Anthropic's own admissions — everything is in the article. Receipts, not feelings.
