The Anthropic API has options to enable ‘thinking’ in its newest models (Sonnet 3.7, Sonnet 4 and Opus 4). As far as I can see, there’s no option to enable this in Zapier, so currently all the requests to the new models are not doing any thinking. 

Anthropic docs for this are here: https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking#how-extended-thinking-works

Would be great to have this as an option (and also to have the thinking tokens/summaries as a variable we can work with too), as it unlocks the higher levels of capability (there are some Zaps I have that will only work with Opus thinking atm). 

 

 

Hi ​@Zeus! 👋

 

At the moment, the Anthropic Claude) app in Zapier doesn’t expose the tool_choice or related parameters needed to enable Extended Thinking with Anthropic models like Claude Opus 4 or Sonnet 3.7. So out of the box, those advanced capabilities aren’t accessible through the Zapier UI.

 

If you need access to Claude’s Extended Thinking or summaries for your workflows, it might be worth looking into calling the Anthropic API directly using a Webhooks by Zapier step. That should let you manually pass the relevant parameters supported in their API and work around the current limitations.

 

I hope this helps!
