Lead Story

Twitch streamers can now opt out from training Amazon's AI

Twitch has introduced an opt-out mechanism allowing creators to prevent their content — streams, VODs, clips, channel chats, and profile images — from being used to train Amazon's generative AI models. The change gives streamers a meaningful degree of control over how their creative output is consumed by the company that owns the platform.

The move arrives as creator communities across every major platform have pushed back against the quiet use of their work for AI training. Whether opt-out is enough — versus the opt-in standard many advocates demand — is already drawing debate, but it marks a notable concession from one of tech's largest AI operators.

AI & Music

Guitar company D'Addario admits that AI music was used in a promotional video

After nearly two weeks of denial, explanations ranging from "low-quality microphones" to production technicalities, and mounting evidence from observers online, D'Addario has confirmed that AI music tool Suno was used to create audio in a recent promotional video. The admission is a landmark moment for brand accountability in the AI era — and a cautionary tale for any company tempted to slip AI-generated content past an audience that increasingly knows what to listen for.

AI Agents

Grok is now an AI ‘teammate’ you can assign work

xAI has launched Grok Bot, a persistent AI agent service that operates like an independent team member inside your existing tools. Each bot runs in its own cloud environment, can sign into apps and websites on your behalf, and executes multi-step workplace tasks without requiring you to stay in the loop. The launch represents xAI's clearest push yet into the agentic AI space that OpenAI, Anthropic, and Google are all racing to define — and frames the competition not around chatbots, but around autonomous digital labor.
