2. ChatGPT Launches in Apple CarPlay with Voice-Only Interface

OpenAI. ChatGPT is now available directly from Apple CarPlay for users running iOS 26.4 or newer with the latest ChatGPT app. The integration is voice-only — no text responses appear on screen, and on-screen controls are limited to mute and end-conversation buttons per Apple’s CarPlay app guidelines. Users can start conversations from the CarPlay dashboard, review recent conversation titles, and end sessions from the car display. A dedicated wake word is not supported; the app must be tapped to open from CarPlay. Source

3. GPT-4o Retired from All ChatGPT Plans

OpenAI. GPT-4o reached end-of-life across all ChatGPT subscription tiers on April 3, 2026, as OpenAI completes its transition to GPT-5.4 and GPT-5.4 Thinking as the default models. Users on Free, Plus, and Pro plans who had been using GPT-4o for its reliability and predictable formatting will need to migrate workflows to current models. API access continues under a deprecation policy with a sunset date to be announced separately. Source

4. OpenAI Details AI Superapp Vision Backed by $122 Billion Round

OpenAI. Following the close of its $122 billion financing round, OpenAI outlined its plan to build what it calls the “infrastructure layer for intelligence itself” — a unified AI superapp that integrates ChatGPT, Codex, search, browsing, and agentic capabilities into a single agent-first product experience. The company described the goal as serving users across every device and context, with write capabilities for Box, Notion, Linear, and Dropbox already shipping as early examples of cross-platform agent integration. The superapp strategy places OpenAI in direct competition with Apple, Google, and Microsoft for AI-mediated computing. Source
