anthropic seems to be prepping for a new model or major update. docs for "opus 5" and a new "thinking" feature just appeared in their sitemap.

looks like claude is getting some significant upgrades! new docs hint at an "opus 5" model and a "thinking" concept with tooling workflows. very interesting.
