AI News: OpenAI Absolutely Cooked This Week!

TL;DR

OpenAI dropped GPT 5.5 Instant, new realtime voice models, and Codex updates while Anthropic made a surprise SpaceX compute deal and Claude got Microsoft 365 integration.

Key Points

• 1.GPT 5.5 Instant is OpenAI's new default model for all ChatGPT users. It delivers more concise, accurate, and personalized responses than GPT 5.3 Instant, with better math performance — but it's an incremental update, not a state-of-the-art breakthrough.
• 2.OpenAI launched three new Realtime voice models currently limited to the API. GPT Realtime 2 uses GPT-5-class reasoning; GPT Realtime Translate supports 70 input and 13 output languages; GPT Realtime Whisper streams live speech-to-text — all accessible via platform.openai.com/audio/realtime.
• 3.Codex gained a Chrome plugin and a virtual pet system this week. The Chrome integration lets Codex control browser tabs directly (still buggy at launch), while the /hatch command lets users generate custom ASCII-style pets like 'Wolfie' or import community creations from codeex-petss.net.
• 4.Anthropic's 'Dreaming' feature enables scheduled background memory review for managed agents. Unlike passive memory in Claude or ChatGPT, Dreaming proactively scans past sessions to extract patterns, fix recurring mistakes, and restructure memory stores — a step toward fully proactive AI agents.
• 5.Anthropic signed a surprise compute deal with SpaceX (rebranding as SpaceX AI) to raise Claude usage limits. Despite Elon Musk publicly mocking Anthropic as recently as March 2025, the partnership appears driven by an 'enemy of my enemy' logic — Musk has excess GPU capacity and incentive to help Anthropic compete against OpenAI.
• 6.Grok 4.3 from xAI made benchmark gains but still trails OpenAI, Anthropic, and Google top models. Its key advantage is cost — Grok 4.3 is positioned as cheaper than Claude Opus and top OpenAI models, making it competitive for price-sensitive API users.
• 7.Sam Altman's firing drama resurfaced at trial with damning testimony and leaked texts. Former CTO Mira Murati testified under oath that Altman lied about legal clearance for a model's safety review; leaked texts show Altman, Murati, and Microsoft's Satya Nadella scrambling in real time, including a suggestion that Microsoft acquire OpenAI.
• 8.Adobe Acrobat added NotebookLM-style AI features including PDF podcasts and presentations, while Spotify now supports personal AI-generated podcast feeds. Apple is also reportedly in late development of AirPods with low-resolution cameras to give Siri visual context, and Nvidia is partnering with PTE Group and startup SPAN to install 16-GPU Blackwell mini data centers in new homes.
