Insider speculation: Anthropic may time Claude Fable 5.5 release two weeks before its IPO

Blogger kimmonismus speculates that Anthropic is saving its Claude Fable 5.5 model for one to two weeks before its IPO (expected late October or November) so its significance gets priced into the valuation.
- The quoted message claims Anthropic launched Claude Haiku 5.5 with average running costs 75% below Haiku 4.5, plus gains in coding, computer use and knowledge work, and an adjustable effort setting letting developers choose how much intelligence to spend per task — reportedly approaching Sonnet 5.5 quality.
- The author argues Fable 5.5 should be seen not just as a quality leap but as a strategic release timed to bolster Anthropic's IPO valuation.
All of this is unverified speculation and should be treated with caution.
