    The cost / performance chart shows that in almost all configurations, it looks worse than Opus. Why would you use Sonnet 5.5 on xhigh if you would get better results (higher score, cheaper cost) on Opus 5.5 high?

    Is there a good use case? This isn't like Luna where it's much cheaper/effective just to use Luna in certain situations.

      At low and medium effort it is 1/3 cheaper, at high it’s a step above Opus/low. It only looks worse at xhigh.

        That makes sense. I'm interested in seeing where Haiku 5.5 comes in then when it gets released. It feels like the low intelligence / fast niche will be covered there.

          i'd love to see them re-enter that space but given haiku 5 never happened I wouldn't bet on it

          i think they see what openai charges for luna and just don't want to try and compete

            But they literally stated that they would release Sonnet 5.5 and Haiku 5.5 after Opus 5.5 would be released

              Haiku 5.5 is DOA without a massive price cut. Luna is literally 10x cheaper at current pricing

                It depends entirely on its capabilities. If it is significantly smarter than Luna, which frankly is quite likely, then a lot of people won't mind paying more.

                  Or if its luna at 1000 tok/sec. Speed is what most of my peers care most about these days since less intelligent models can do most grunt work just fine.

              My guess is that haiku will be a mid release. They don’t seem to care to compete for the low end. Something akin to gpt6 sol level intelligence at $1 / $5 pricing. Then not release an update for 6+ months.
