Opus 5.5, GPT Voice, Muse reshape AI week
Riley Brown’s update rounds up three notable AI shifts: Anthropic’s Opus 5.5, OpenAI’s more natural GPT-Live voice experience, and Meta Muse’s push toward mainstream personal agents. Together, they show AI moving from chat interfaces toward persistent, action-oriented workflows.
The interesting story is convergence: frontier models are becoming cheaper and more capable while voice and agents make them easier to use.
