ChatGPT adds filtered search for chats, images, documents
OpenAI has rolled out an enhanced search feature for ChatGPT that adds filters for chats, projects, images and documents, accessible from the sidebar and available on web, iOS and Android. The update aims to make cross-content searches inside ChatGPT faster and the matching results openable directly in the app. The article also notes recent OpenAI developments including the GPT-5.6 family (Sol, Terra, Luna), the agentic offering 'ChatGPT Work', and GPT-Red — a specialized red‑teaming model focused on uncovering security vulnerabilities.
Usability improvements to a major conversational AI (ChatGPT) and announcements of new LLM variants and a dedicated red‑teaming model are relevant to marketing and creative workflows, model safety, and wider GenAI adoption, but they are incremental rather than industry‑shifting.

OpenAI adds filtered chat search and GPT‑Red
OpenAI has rolled out a redesigned search experience inside ChatGPT that centralizes searches in a dedicated sidebar and adds filters to find content across chats, projects, images and documents. The feature is being deployed on the web, iOS and Android and was presented via the official ChatGPT account on LinkedIn; the article also cites ChatGPT’s claimed user base of more than 900 million weekly active users. In parallel, OpenAI introduced GPT‑Red, an automated red‑teaming cybersecurity model designed to discover vulnerabilities such as prompt injection. OpenAI says it trained GPT‑Red at large compute scale and that GPT‑5.6 (including the Sol variant) is trained together with GPT‑Red, with GPT‑5.6 Sol reported by the company as more resistant to such attacks. The piece highlights growing use of automated red‑teaming alongside human teams.
Cerebras stock hits post-IPO low amid Nvidia pressure
Cerebras Systems' stock dropped nearly 20% this week to $166.43, its lowest since the May IPO, after a report that Nvidia would power OpenAI's "Ultrafast" mode for GPT-6.1 Sol, taking a key inference workload away from Cerebras. The stock is down more than 50% from its opening price. Insider selling, including CEO Andrew Feldman and CTO Sean Lie selling over $240 million in shares, exacerbated the decline as lockup restrictions expired. OpenAI CEO Sam Altman responded to speculation, calling Cerebras a "close partner," which helped stock recover almost 3% in after-hours trading. Cerebras' market cap has fallen from $95 billion at IPO to about $39 billion.
