Claude Sonnet 5
The workhorse for busy marketers and social managers. Quick enough to batch a week of content, sharp enough that you can use what it writes.
[ Overview ]
Meet Claude Sonnet 5.
Claude Sonnet 5 is the fast, capable middle of the Claude line, and it is the one to keep open all day. Social media managers, marketers and creators use it for the work that is not hard so much as endless.
Batch a week of captions across four clients in an afternoon. Turn one product page into ten ad variations. Draft the newsletter, the LinkedIn post and the follow-up email from the same brief. Then switch to Images in the same session and generate the graphics to go with them.
Sonnet 5 is the quickest of the three Claudes here, which is why it is the right default for volume. When a job needs more depth, hand the thread to Opus 4.8 or Fable 5 and carry the whole conversation across. All of them come with HiggsChat on one subscription, from $15 a month.
