Luna is comparable to Haiku, not Sonnet.

Totally untrue. Luna and Sonnet 5 are very comparable: https://artificialanalysis.ai/#intelligence https://artificialanalysis.ai/#intelligence Luna is an extremely strong model.

  > Luna is an extremely strong model. By benchmarks, which sadly is a poor measure. Yes Luna is a good model under certain circumstances. Whether it is great for general usage is another story. Sonnet is definitely better when prompts are more vague and it needs to decide things. Luna generally sticks to things very strictly and goes off in bad ways.

    Yes but there is a big, big market for subagents to consume lots of tokens cheaply and condense information up to parent agents. Luna would not be my choice for planning. But an explorer to comb through a codebase to find relevant parts? Or for enterprise retrieval, where it needs to search across many different types of data to see where to focus efforts for a smarter model? Or to wake up periodically to evaluate some conditions and determine if a bigger model should be spun up? Definitely. I've previously found flash (for all the hate it gets) to be good for these kinds of things. Haiku was fine but it's ancient.

      > Yes but there is a big, big market for subagents to consume lots of tokens cheaply and condense information up to parent agents. That's again not some "intelligence factor" here. Different agents work for different use cases. Luna wins some. Terra wins some. Sonnet wins some. Flash was really good at exploring. So I'm not sure what your point is? There's a big market for everything. Even within the market you describe it's likely not a Luna-size fits all either.

    I'm actually finding Luna to be an extremely strong model in practice. I almost exclusively use it with xhigh or max effort, but when run like that it's been an incredibly cheap little workhorse for most development work. I'm still leaning on Sol for planning and debugging, but when it's time to start pumping out code I've been leaning into Luna (Max) and I've been enjoying it! And that was before the price drop, it's going to feel practically free at this point

      Yes, I've seen this too and how Luna xhigh is so good that Terra doesn't really serve a purpose because beyond that you can continue at Sol medium. This can be the most cost efficient way, and especially now!

Anthropic basically downgraded all their tiers when they released Mythos, no nah, Sonnet 5 is the successor to Haiku 4.x

In my real world use Luna is as useful to me as Sonnet. And it gets stuff done faster and follows my instructions more closely.
