Grok goes agentic, while Anthropic is watermarking everything | Your weekly product briefing

August 17, 2026/1 min read

Mike Belsito covers three stories this week that matter to product pepole this week. xAI's Grokbot launches in public beta as a persistent digital co-worker that non-technical users can actually configure; Anthropic rolls out invisible watermarks across all Claude outputs in response to the EU AI Act, with a December 2026 deadline for full coverage; and Meta releases Llama Glimmer, a 30-billion-parameter open-weight model built for local agentic work that could finally open AI-powered features to privacy-sensitive verticals. Mike also shares details on his upcoming book and how to vote for his SXSW session.
