Every major model update gets covered as a headline. The useful question for a working agent isn't whether it's smarter in the abstract, it's which of your existing workflows just got more reliable, and which new one is now worth building.
Take the prompt you rely on most (an underwrite, a memo, a client email) and run it again on the new model. Compare the output line by line, not by feel.
A larger working memory means longer document packs and messier multi-file uploads become usable without the drift covered on Day 22.
A capability that was 80 percent reliable last quarter and is 95 percent reliable now is the signal to move a workflow from manual review to a scheduled loop.
A model's score on a coding or math benchmark says little about how well it reads a contract or a listing sheet.
Re-test the one or two workflows that matter most before assuming everything downstream needs a rewrite.
A capability jump is only useful if the plan you're on actually includes it. Check before promising a client a new workflow.
