Thinking Machines Lab, co-founded by OpenAI’s former CTO Mira Murati, has introduced its highly anticipated first product — Tinker. Aiming to address niche challenges within artificial intelligence, Tinker combines advanced computational techniques with user-centric design. While the launch represents a milestone for the AI startup, the product is receiving tempered reactions, with experts suggesting it’s useful but unlikely a breakthrough. Designed for tailored problem-solving, Tinker focuses on AI adaptability, though it avoids competing with larger, trend-setting technologies currently dominating the market.

Meta announced that starting December 16, it will incorporate users’ interactions with its AI tools — such as voice and text chats — into its advertising algorithms across Facebook and Instagram. This move aims to enhance ad targeting by combining AI chat data with existing behavioral signals like likes and follows. For instance, a conversation about hiking gear could lead to personalized content and advertisements related to outdoor activities. However, Meta has stated it will exclude sensitive topics — such as religion, health, and political views — from ad targeting. The update will be implemented globally, except in the European Union, the UK, and South Korea, where stricter data privacy regulations apply. Users will be notified of these changes starting October 7.

Meta has launched Vibes, its own AI-video app tied to its advertising platform. OpenAI countered by unveiling Sora, an iOS app that mixes AI-video generation with social features like a scrollable feed and “cameo” tools to insert users into videos. Sora is currently invite-only and uses live video prompts during onboarding to authenticate users and prevent impersonation. Although OpenAI insists it has no immediate plans to monetize via ads, the shift toward video and social engagement could eventually open that door. Meta, by contrast, is moving swiftly to incorporate AI-driven ads and experiences starting in December.

OpenAI has launched Instant Checkout, letting U.S. users buy products inside ChatGPT. The feature runs on the open-sourced Agentic Commerce Protocol, co-developed with Stripe, and compatible with MCP and standard APIs. OpenAI is starting with Etsy sellers and plans to add over a million Shopify merchants, including Glossier, Skims, Spanx, and Vuori. Users tap Buy and confirm shipping and payment in chat. Subscribers can use stored cards. OpenAI takes a small merchant fee from the transaction. The protocol uses encrypted tokens and could pave the way for agentic shopping. The move targets the monetization of 700 million weekly users and could challenge Google’s referral model.

Apple is reportedly developing an internal chatbot called Veritas as part of its Siri upgrade effort. Employees can interact with it much like ChatGPT or Gemini — asking questions, revisiting past threads, and generating responses. But there’s a catch: it’s not meant for public release (at least not yet). Instead, Apple seems to be using it as a sandbox to experiment with new Siri capabilities like in-app actions and personalized search across private data. What makes this interesting is that it shows how seriously Apple is approaching its AI pivot, testing internal tools before opening them up, and possibly leaning on rivals (like Google’s Gemini) in the interim.
