@simonw If your own power users can't even rank your model lineup without guessing, that's not a fun trivia question, it's a marketing failure. Simpler naming would kill threads like this one before they start.
@simonw Honestly I just want Haiku 5 at DeepSeek 4 Flash price. I'm tired of these expensive ass model releases.
Opus 5 should be seen more like "5.1". If it's better than Fable 5, I would expect them to label it 5.1. This isn't new, there were brief windows during the 4 line where Sonnet was better than Opus because of training improvements across the board. Sonnet 3.5 smoked Opus 3 Sonnet 4.5 smoked Opus 4.1 Sonnet 4.6 was slightly better than Opus 4.5 (according to benches) Re: tiering, definitely Haiku < Sonnet < Opus < Fable & Mythos. Note that fable === mythos, just has safeguards put in front of model. Same weights, same tier.
I've seen a few people predicting that Opus 5 will be out soon and will be better than Fable 5, but have Anthropic clarified how their relative naming scheme works yet? I assumed it was Haiku < Sonnet < Opus < Fable < Mythos - but is Fable meant to go between Sonnet and Opus?
