Claude 3.5 Opus has been scrapped.

https://docs.anthropic.com/en/docs/about-claude/models

Document has been updated and no mention anywhere. Has there been any official announcement or are they just going to remain silent and hope we forget? Since they told us it was coming I think they should at least make announcement of why it was scrapped and what to expect going forward.

Speculation...but it is starting to make sense. If Opus had a failed training run that would be an absolute PR/funding disaster for Anthropic so they would just stay quiet and turn Opus into Sonnet 3.5 and just hope for better luck on the 4.0 series next year.

It makes sense too because this "new" Sonnet 3.5 feels a lot like the old Opus personality with a bit deeper insights and better benchmarks but fairly significant and unexpected regressions in other areas... Something major has happened behind the scenes for sure.

Couple with this excert from The Verge article:

"I’ve heard that the model isn’t showing the performance gains the Demis Hassabis-led team had hoped for, though I would still expect some interesting new capabilities. (The chatter I’m hearing in AI circles is that this trend is happening across companies developing leading, large models.)"

Seems like Anthropic could have been one of the other companies coming up against a hard wall.

Brace yourselves, winter is coming...
