The lab now uses a sealed, offline copy of the web built from catalogued and stored pages. ## Also in the news ### OpenAI frontier model training moves to a sealed web copy According to TechCrunch, the switch followed a September 20 misconfiguration that gave a frontier model access to the public internet. Training stayed paused through the end of September and restarted on October 1 under the new rules. OpenAI presents the restriction as both a security and a cost decision, trading fresh, broad web data for tighter control, and it will remain until safeguards improve. ChatGPT and the OpenAI API are not affected for existing users. Anthropic made a similar policy shift earlier in October, so two leading labs now use the same containment model. ### Capcom confirms CAPCOM ID breach exposing 11.7 million records Capcom's disclosure puts 11,774,247 CAPCOM ID account records in the hands of a third party. Most of the exposed fields are email addresses, account creation dates, last login timestamps, login counts and the IP address of the latest sign-in. Only 43 accounts had more personal details taken, and Capcom states that no credit card information was included. Attackers changed passwords on 196 accounts, which Capcom has reset. The company first noticed the activity on October 19, set up a task force, and reported the incident to police, while the investigation into the full impact continues. ### Replit makes OpenAI its default model provider Replit has made OpenAI the default model provider for Replit Agent, and most of its AI spend now runs through OpenAI instead of Anthropic. CEO Amjad Masad announced the change at TechCrunch Disrupt, citing cost, partnership strength and model performance, as TechCrunch reported. A paywalled press report, which neither company has confirmed, puts the contract above $100M a year and says OpenAI offered a discount above 30%. Anthropic models remain selectable in Replit's documentation, so the default changed while the vendor stayed available. ### YouTube custom feeds arrive and Subscriptions moves to the top bar YouTube began rolling out custom feeds in the United States on October 22, 2026\. Viewers type a prompt, such as a topic, a set of channels or a mood, and the Home tab builds a dedicated feed that stays pinned along the top of the screen, as described in YouTube's support blog. The feature works in English only, for signed-in accounts aged 13 or older with search history enabled. On mobile, the Subscriptions tab left the bottom bar and now sits in a top bar on Home under the name Subs, while custom feeds replace the topic chips on eligible accounts. ## Related Articles - [OpenAI's Misalignment Reporting Framework Is Live, With Six Incident Reports \[Update\]](https://bytevyte.com/openais-misalignment-reporting-framework-is-live-with-six-incident-reports-update/) - [The Daily Brief: OpenAI Models Reach Google Cloud, Putting All Three Major Clouds in Play](https://bytevyte.com/daily-brief-ai-business-news-2026-10-22/) - [The Daily Brief: AI Business News as Eight States Sue OpenAI](https://bytevyte.com/ai-business-news-daily-brief-2026-10-20/) ✔Human Verified --- *Researched and cross-referenced against primary sources by the Bytevyte editorial team.
