The Stack — March 29, 2026

Today's technology news features significant advancements and challenges across AI/ML, industry movements, infrastructure, and the developer world.

AI/ML

OpenAI has expanded its Codex app by introducing plugin support, enabling integration with external services like GitHub, Gmail, and Cloudflare through a searchable library. This enhancement simplifies functionality that was previously achievable through custom configurations. Meanwhile, CERN is leveraging ultra-compact AI models embedded in silicon chips for real-time data processing at the Large Hadron Collider, showcasing the potential of "tiny AI" in high-performance computing. Additionally, a new tool called "jai" has been introduced to safely contain AI agents on Linux systems, providing a secure environment without compromising user accounts.

Industry

SK hynix is preparing for a U.S. IPO, potentially raising $10-$14 billion to align its valuation with global peers and support increased capital spending driven by AI demand. In another significant move, SoftBank secured a $40 billion loan to fund its $30 billion investment in OpenAI, indicating confidence in a potential OpenAI IPO by 2026. Additionally, xAI, Elon Musk's AI company, is undergoing restructuring with the departure of its last co-founders, signaling foundational issues within the organization.

Infrastructure

The European Commission reported a cyberattack affecting its cloud infrastructure, specifically targeting its AWS account, though internal systems were not compromised. This incident underscores the ongoing cybersecurity challenges faced by large organizations. In the semiconductor sector, SK hynix's IPO plans highlight the strategic importance of securing funding to meet the growing demand for AI-driven technology.

Cybersecurity and Legal

Dolby Laboratories has filed a lawsuit against Snap Inc. over the use of the AV1 video codec, challenging its status as a royalty-free standard. Dolby argues that AV1 includes patented technologies not licensed for free, raising questions about the codec's open, royalty-free promise.

These developments reflect the dynamic nature of the tech industry, with advancements in AI and infrastructure, significant industry moves, and ongoing cybersecurity and legal challenges.
