Sonnet 5 seems to have gotten quite bad at coding now, based on what a few folks I trust are reporting. Which makes me wonder whether Sonnet is actually Haiku... Are they just sliding everything up one family so we keep paying what we used to pay for a better tier? The labs want you to think in terms of the full model family together anyway. Their whole economic interest is you staying on their stack. Genuinely curious if anyone else is noticing this.
