OpenAI's GPT-5.4 Pro model has reportedly solved Erdős open problem #1196 in approximately 80 minutes, with another 30 minutes to format the solution as a LaTeX paper. Mathematician Terence Tao notes the solution reveals a previously undescribed connection between integer anatomy and Markov process theory.
OpenAI has released GPT-5.4-Cyber, a fine-tuned variant of GPT-5.4 built for defensive cybersecurity work including binary reverse engineering. Access is initially restricted to a few hundred verified security professionals, with expansion planned to thousands of individuals and hundreds of teams in coming weeks.
HCompany has released HoloTab, a Chrome extension that uses its Holo3 computer-use model to automate browser tasks. The free tool requires zero technical setup and includes a routine recording feature for repetitive multi-step workflows.
Baidu has released ERNIE-Image-Turbo, a distilled text-to-image diffusion transformer that generates images in 8 inference steps. The model runs on consumer GPUs with 24GB VRAM and supports resolutions up to 1376×768, with claimed strengths in text rendering and structured generation tasks.
Baidu has released ERNIE-Image, an 8B parameter text-to-image generation model built on a single-stream Diffusion Transformer architecture. The model is designed for complex instruction following, text rendering, and structured image generation, and can run on consumer GPUs with 24GB VRAM.
Anthropic has launched a cloud service called routines that allows Claude Code users to run automated AI tasks on company infrastructure. Daily limits range from 5 routines for Pro users to 25 for Team/Enterprise customers.
Google launched a Windows desktop application that provides keyboard shortcut access to Gemini AI search. The app uses Alt+Space to trigger a search bar that can query the web, local files, installed apps, and Google Drive, with built-in Google Lens screen sharing capabilities.
OpenAI has released GPT-5.4-Cyber, a variant of GPT-5.4 fine-tuned specifically for defensive cybersecurity use cases. The release accompanies the company's Trusted Access for Cyber program, which allows users to verify their identity via government ID to gain access to cybersecurity-focused tools.
OpenAI announced GPT-5.4-Cyber, a variant of GPT-5.4 fine-tuned for defensive cybersecurity work. The model features binary reverse engineering capabilities and reduced safety restrictions, but access is limited to authenticated security professionals through the company's Trusted Access for Cyber program.
OpenAI released GPT-5.4-Cyber, a model variant designed for defensive cybersecurity tasks with fewer restrictions on dual-use queries. Access is controlled through a tiered verification system in the Trusted Access for Cyber program, targeting thousands of vetted users compared to Anthropic's 40-organization Mythos Preview rollout.
The UK's AI Safety Institute published an independent evaluation confirming Anthropic's Claude Mythos is highly effective at finding security vulnerabilities. The evaluation revealed a linear relationship: more tokens spent equals more exploits discovered, transforming security into an economic arms race.
Google Home's April 2026 update addresses Gemini voice assistant reliability issues. The update improves speech detection to reduce mid-sentence interruptions, speeds up responses to simple queries, and enhances music playlist recognition even when names are misspoken or in noisy environments.
