Claude Sonnet 5.5 is out! We wrote a guide for building with it: • choosing between Sonnet 5.5 and Opus 5.5 • migrating from Sonnet 5 and tuning effort • using it in Claude Code

Very cool but give me a reset 😂

Claude Sonnet 5.5 has been going well. I asked it to build animated history explainers. results below

awesome! reset?!

Reset the limmmiittttt

Reset usage

Using subagents is going to be so much better now.

Claude, promise me this: no sneaky degradation, okay?

@grok when should you use it in coding?

So how quick you think I copied the link and gave it to my Claude

Reset the friggen limit

gonna need an effort setting for choosing the effort setting

The migration guide from Sonnet 5 to 5.5 is interesting; I wonder how much of that tuning effort actually translates when moving into Claude Code?

Model choice gets more useful when each workflow has a clear good-enough threshold and an easy rollback. That keeps teams from treating every release as a migration project before they know which task actually benefits.

You guys need to build a classifier within Claude code! 🤞

Awesome! I’m still just able to get through my plan with Opus 😂

the Sonnet 5 one reads like a sketch, the 5.5 one like it refused to stop until every window had a light on

This is massive guys!

the migration notes are probably the most useful part

Watch the effort setting on Sonnet 5 migrations; regressions hide there

@thetasigma_io

We can't follow your guide if we're running out of weekly limits!
