"The vast majority of Codex is built by Codex," OpenAI told us about its new AI coding agent. In interviews with Ars Technica this week, OpenAI employees revealed the extent to which the company now relies on its own AI coding agent, Codex, to build and improve the development tool. "I think the vast majority of Codex is built by Codex, so it's almost entirely just being used to improve itself," said Alexander Embiricos, product lead for Codex at OpenAI, in a conversation on Tuesday.
It may sound like a trip through the produce aisle, but leading AI companies have something much more important on their lists. Meta, OpenAI, and Google have all relied on food-related names for their sometimes secretive plans for future AI models. Thinking with your stomach is nothing new for Silicon Valley, just look at the assortment of desserts Android assembled over the years before Google had its fill.
The company was so worried about the possibility of the upstart chatbot disrupting its Search business, executives sounded a "code red" alert inside of the company and called Sergey Brin and Larry Page out of retirement to help it formulate a response to OpenAI. It then rushed out Bard, announcing its first commercial chatbot on February 6, 2023. Google's stock tanked days later when the AI incorrectly answered a question about NASA's James Webb Space Telescope during a public demo.
It looks like ChatGPT User (the user action bot) will no longer comply to robots.txt rules (Open changed the wording from "the following robots.txt tags", referring to all 3 user agents to "OAI SearchBot and GPTBot robots.txt tags") OAISearchBot is no longer used to feed the navigational links in ChatGPT answers (blocking this bot does not mean your will not appear in the links)
"OpenAI was the golden child earlier this year, and Alphabet was looked at in a very different light," said Brett Ewing, chief market strategist at First Franklin Financial Services. "Now sentiment is much more tempered toward OpenAI."
OpenAI's head of ChatGPT, Nick Turley, however, dismissed those rumors in a post on X on Saturday. "I'm seeing lots of confusion about ads rumors in ChatGPT. There are no live tests for ads - any screenshots you've seen are either not real or not ads. If we do pursue ads, we'll take a thoughtful approach," he said. "People trust ChatGPT and anything we do will be designed to respect that."
An anti-AI activist in California has been missing for about two weeks, according to The Atlantic, and now his friends are scared for his safety while San Francisco police fear he could target OpenAI employees. The activist in question, a 27 year old named Sam Kirchner, helped start the Stop AI group last year with a commitment to non-violent protest, but became frustrated and angry that the group's efforts didn't go quickly or far enough as he increasingly saw AI as a
The test model produced confessions as a kind of amendment to its main output; this second response reflected on the legitimacy of the methods it used to produce the first. It's a bit like using a journal to be brutally honest about what you did right in a given situation, and where you may have erred. Except in the case of GPT-5 Thinking, it's coming clean to its makers in the hopes of getting a reward.
Zuckerberg, Chen said, has personally "hand-cooked" and "hand-delivered" soup to researchers he wanted to recruit away from OpenAI. And it wasn't a joke, the executive insisted. "It was shocking to me at the time," Chen admitted. But in Silicon Valley, if the enemy brings broth, you must respond in kind. Chen confessed he has now adopted the tactic, delivering soup to his own recruits as he hopes to poach talent from Meta.
Altman told employees in an internal memo Monday they should focus on upgrading the AI chatbot's speed, reliability and ability to answer more questions while also allowing users to better personalize their experiences, according to The Wall Street Journal and news site the Information. OpenAI will delay other planned initiatives, such as a rollout of more advertising on the chatbot and specific versions for health and shopping, while prioritizing ChatGPT's improvement, the memo stated.
The elephant in the OpenAI room is Google's Gemini 3 AI model, which debuted to widespread praise. The model's capabilities demonstrated that Google is no longer far behind in the AI race. It's not just OpenAI that's unnerved, either. Nvidia, the world's most valuable company by market cap, recently found itself defending its AI chips after a report about Google's own chip progress.
Severson will now serve as Vice President, Head of Global Business Development at Sam Altman's AI company. "Joining OpenAI at such a defining moment in technology is an opportunity I couldn't pass up," Severson wrote in his LinkedIn post. "I'm drawn to moments of transformation - and it's rare to be part of something so squarely at the frontier of what's possible."
Lee and I both agreed that few investors fully appreciate how central SoftBank has become to the global AI capital stack. The company owns stakes in OpenAI, has backed emerging infrastructure projects like the Trump-aligned Stargate initiative, and effectively repositioned itself as the Berkshire Hathaway of AI by reallocating its Nvidia profits into higher-risk frontier plays. Yet unlike traditional cash-rich tech giants, SoftBank must borrow to fund its commitments. That leverage profile is now front and center.
It has been all good news for OpenAI this year. It reached a valuation of $500 billion. Its CEO, Sam Altman, stood next to President Trump in the White House early this year during the announcement of a new $500 billion Stargate AI infrastructure program. It settled a fight with Microsoft (its largest shareholder, with a 24% stake) over becoming a for-profit company. And it created financial partnerships with Oracle, Nvidia, Softbank, and AMD.
