OpenAI launched GPT-4.5 Instant as the new default ChatGPT model — more concise, personalized, and available to all users including free tier.
2
Three new OpenAI Realtime voice models debuted (GPT Realtime 2, Realtime Translate, Realtime Whisper), currently API-only but demoed with impressive live translation across 70+ languages and background listening mode.
3
Anthropic signed a compute deal with SpaceX and committed $200 billion to Google Cloud to raise Claude usage limits, despite Elon Musk having publicly attacked Anthropic as recently as March 2025.
4
Explosive text messages between Mira Murati and Sam Altman during the 2023 OpenAI board crisis were revealed in the Musk trial, showing real-time chaos including Altman offering to walk away and a suggestion that Microsoft acquire OpenAI.
