YouTube Begins Automatically Labeling AI-Generated Videos

On May 27, YouTube launched a feature that automatically detects and labels AI-generated content. Disclosure of AI-generated content, which previously relied on creators self-reporting, will shift to a system where the platform itself makes the determination. The feature detects photorealistic AI-generated content, and the labels will also be displayed more prominently. As a countermeasure against the spread of misinformation that has come with the rise of generative AI, it's fair to say the direction is now clear: major platforms are taking on this responsibility themselves.

ElevenLabs' Music Generation Model Supports Mid-Track Genre Switching

ElevenLabs, the voice AI company, announced a new model that can switch genres partway through a track.

AI's expressive range in music production has clearly taken another step forward.

OpenAI Builds Autonomous Tax Agents with Codex

OpenAI, together with Thrive and Crete, has built a "self-improving" tax filing agent using Codex. Beyond automating tax filings, it delivers continuous accuracy improvements and faster workflows.

The shift toward Amazon's AI being used as e-commerce infrastructure has begun.

Former Google and Apple Researchers Launch Trajectory to Tackle Continual Learning AI

Former Google and Apple researchers have founded Trajectory, a startup building "continual learning" mechanisms that make AI smarter the more it is used. The company's hypothesis is that the rapid iteration cycle proven by vibe coding can be applied to AI products at any company. It's one answer to the problem that today's LLMs lack a feedback loop.

China Moves to Keep Its AI Talent from Leaving

While China's AI boom is producing world-class talent, the Beijing government is stepping up efforts to curb the outflow of top researchers abroad. According to TechCrunch, China is strengthening incentives for talent to stay in the country and pursuing policies to discourage emigration. In the AI development race, securing talent is becoming a key axis alongside semiconductors and compute resources.
