1. ChatGPT gets Grok-style model picker with new GPT-5 modes
ChatGPT.
“Auto”, “Fast”, and “Thinking” are the new modes for GPT-5 that all ChatGPT users can select.
“Auto” appears to work like GPT-5’s model router that OpenAI initially announced.
Elon’s Grok also shows modes including “Fast” and “Expert”.
GPT-4o, GPT-4.1, and o3 are back for paid users — just days after being deprecated last week.
Users can add GPT-4.1 and o3 models from ChatGPT’s settings, while GPT-4o is in the model picker by default.
Relatedly, ChatGPT has received Gmail, Calendar, Contacts integration for Pro subscribers.
GPT-5 routing sets the stage for ad monetization, argues AI research firm SemiAnalysis

3. Perplexity offers $34.5B for Google Chrome, ~2× its own $18B valuation
Several investors, including major VC funds, have agreed to fully back the deal, the startup said.
Estimates of Chrome’s enterprise value vary, ranging between $20B-$50B.
The offer may signal to Judge Amit Mehta that a buyer exists if he orders a sale.
Mehta is weighing whether to force Google to sell Chrome to loosen its grip on web search.
“[D]esigned to satisfy an antitrust remedy in highest public interest,” Perplexity said of its offer.
Google hasn’t indicated a willingness to sell Chrome.
4. Anthropic offers Claude chatbot to U.S. lawmakers for $1, following OpenAI
