It is not often we get a years worth of improvement in one model release but here we are. There was no Haiku 5.0 5.1 or any other new model in the last year.

It looks like it excels on low context projects.

For big context projects Luna may be better. I still haven’t tested how they compare in writing quality.

Hi @thomasumstattd,

As Danny promised, Haiku 5.5 has been added before the end of the day! We’re excited to see what the newest Haiku model can provide for Pickaxe users. Let us know what you think!
