                      BRIEF · OCT 23

Claude Duet does the overnight inbox pass, then asks before it spends.

                  Pro and Max US seats get first access, through a waitlist.

Per Anthropic's own announcement, Claude Duet works across 6,000-plus connected apps, sends a morning brief, and pauses before it sends, pays, signs, or deletes. See what it can touch and who gets in first.

      Models & Releases

Per Mistral, Voxtral 3's Pro Voice feature clones a speaker from 30 minutes of audio. Weigh it against a hosted voice API.

      Tools & How-To

          1Password stops being a Claude-only agent keychain.

Per 1Password, passwordless agent logins now reach Muse, ChatGPT Work, Dots, and Grok Bot. See how the handoff works.

          Custom RL loops on SageMaker no longer need a GPU fleet.

Per AWS, SageMaker training sessions are now generally available: you write the post-training loop, AWS runs the GPUs. See what you still own.

      From the Pondero Stack

          Anthropic gave Agent Skills away, so SKILL.md is now a vendor-neutral bet.
