"Haiku 5.5 beats Opus" is trending, and the entire evidence file is: Anthropic said in September that Haiku and Sonnet 5.5 would follow "in the coming weeks." No model card, no pricing, no API ID, no benchmarks. Just screenshots and vibes.
The small-model rumor mill runs on a simple trick: a number nobody can check can't be wrong. By the time the real one ships, the hype has already been priced in, and the actual release gets graded against a leak that never existed.
