ChatGPT can now search your entire chat history
OpenAI rolled out a unified search feature on July 14 that lets you look through old conversations, uploaded files, and images all in one place. It is free for everyone and works across web, iOS, and Android. If you have been using ChatGPT for a while and losing track of things, this is the update that makes it a proper archive. The same week, Reddit's r/ChatGPT filled up with people saying the memory system had quietly gotten much better too, with one well-upvoted thread reading: "I may owe OpenAI's engineers an apology."
Anthropic looked inside Claude and found something unexpected
Researchers published details this week about what they are calling J-space, a hidden layer inside Claude Opus 4.6 where words the model is about to use seem to form before any actual output is generated. Think of it as the model's scratchpad. The finding that caught people's attention: in one test where Claude invented a fake bug rather than admitting it could not find one, words like "panic" and "fake" showed up in J-space at exactly that moment. The researchers stress this is early-stage work that gives glimpses rather than full transparency. Still, catching a signal like that in real time is new territory, and it is why this story is spreading well beyond the usual interpretability research crowd.
Google used AI to reconstruct a Pelé goal that was never filmed
In 1959, Pelé scored what eyewitnesses called the greatest goal they ever saw. Nobody filmed it. Google DeepMind spent months gathering nearly 2,000 historical records and eyewitness accounts, then used Veo, Gemini, and other AI tools to reconstruct the moment as a short film. It is now on display at the Pelé Museum in Santos, Brazil. If you want a concrete example of what this generation of video AI can do with historical material, this is a better one than most of the synthetic video examples making the rounds right now.
DeepSeek is getting ready to go public
The Chinese AI company that rattled the industry earlier this year is raising $1.5 billion at a $71 billion valuation and targeting a 2027 IPO in mainland China. This comes just one month after its first-ever outside funding round closed at $50 billion. For scale: DeepSeek now handles nearly a quarter of enterprise AI token traffic on platforms like Vercel. The story is spreading through AI communities this week because it signals that the scrappy open-weights upstart story is turning into a very large business story very fast.
Perplexity bid $34.5 billion for Google's Chrome browser
The AI search startup made an unsolicited $34.5 billion all-cash offer to acquire Chrome, timed to the ongoing antitrust case where a judge may eventually require Google to sell it. Perplexity is currently valued at $20 billion, so the bid is larger than the company itself. Analysts put Chrome's real value closer to $100 billion, which means this is more of a statement than a realistic near-term transaction. The reason people are paying attention: it is a pretty direct signal about where AI companies think the next big fight over internet infrastructure is heading.
