Google Adds Custom Tones to AI Podcasts in NotebookLM

🚀 TodayOnAI Insight: Google is expanding NotebookLM with customizable tones and voices for its AI-generated Audio Overviews, letting users choose how their documents are summarized—whether as a deep analysis, a concise recap, a critical review, or a debate. It’s a notable step in making AI-driven content feel more personal, purposeful, and versatile.

🔍 Key Takeaways:

• Users can now select from four Audio Overview styles: Deep Dive, Brief, Critique, or Debate, each offering a different tone and structure.

• Each format is powered by two virtual hosts and varies in length and depth to match user intent.

• Google has also added new AI voices, addressing a top user request for greater personalization.

• The update follows recent additions like Video Overviews and standalone Android/iOS apps.

• New content includes featured notebooks curated by authors, researchers, and nonprofits.

• The features are rolling out globally this week across all supported languages.

💡 Why This Stands Out: As generative AI becomes a co-author and collaborator, tone control marks a key evolution—moving from static summarization to adaptive storytelling. Google’s latest upgrade to NotebookLM not only enhances utility for students, professionals, and researchers, but also signals a growing demand for AI that communicates with nuance. Will future assistants be judged less on accuracy and more on how well they match our communication style?

APPLE

Apple Delays Siri Overhaul, Leans on Google’s Gemini for AI Search

🚀 TodayOnAI Insight: Apple is reportedly testing Google's Gemini AI inside Siri as part of a broader overhaul delayed to 2026. The move signals Apple’s willingness to outsource core generative AI capabilities as it tries to close the gap with rivals like OpenAI and Google.

🔍 Key Takeaways:

• Apple and Google have reached a formal agreement to test Gemini in Siri, according to Bloomberg’s Mark Gurman.

• If successful, Gemini could also power AI features in Safari and Spotlight across iOS.

• The revamped search experience will include AI-generated summaries, multimedia responses, local data, and personal context integration.

• Apple has delayed its major Siri upgrade to 2026 as it evaluates whether its in-house models are competitive.

• Spotlight, once seen as a lightweight Google rival, could now lean on Google's own technology to expand its capabilities.

💡 Why This Stands Out: Apple’s pivot to Google’s AI marks a rare concession: even the world’s most vertically integrated tech company may need to license foundational models to remain competitive. It reflects the growing pressure to match the conversational fluency and contextual awareness of today’s leading AI assistants. If Apple can't rely solely on its own models, what does that say about the broader landscape of proprietary AI development?e or manipulated reviews. As with Amazon and Google, Apple’s move reflects a growing trend: turning raw customer feedback into digestible AI-driven insights.

CoreWeave/AI

CoreWeave acquires agent-training startup OpenPipe

🚀 TodayOnAI Insight: CoreWeave is acquiring Y Combinator–backed startup OpenPipe to deepen its AI cloud offerings with reinforcement learning tools. The deal strengthens CoreWeave’s strategy of moving beyond infrastructure into enterprise-focused AI development.

🔍 Key Takeaways:

• OpenPipe builds ART (Agent Reinforcement Trainer), an open-source toolkit for developing custom AI agents.

• CoreWeave will integrate OpenPipe’s self-learning tools with its high-performance AI cloud to boost reasoning and agentic tasks.

• Terms of the deal weren’t disclosed, but OpenPipe raised $6.7M in seed funding in March 2024 from notable investors, including GitHub and DeepMind veterans.

• This acquisition follows CoreWeave’s March purchase of Weights & Biases, signaling a push to cover more of the AI development stack.

• OpenPipe’s team and customers will transition to CoreWeave, expanding its reach to both large AI labs and smaller enterprises.

💡 Why This Stands Out: Reinforcement learning is becoming a key differentiator in enterprise AI, enabling models to adapt more effectively to specialized tasks. CoreWeave’s move to pair massive compute power with in-house agent training reflects a broader trend: cloud providers racing to control not just the hardware, but the full AI development workflow. The question now—will enterprises prefer bundled infrastructure-and-tooling ecosystems or continue piecing solutions together?
