AI Roundup: March 26, 2026

1. OpenAI Shuts Down Sora Six Months After Launch, Collapsing a $1B Disney Deal

OpenAI discontinued its Sora AI video generation app and API, citing unsustainable compute costs relative to text generation. The shutdown immediately terminated a pending $1 billion strategic investment from Disney, which had intended to license Sora for characters across Disney, Marvel, Pixar, and Star Wars franchises. Sam Altman confirmed a new video model codenamed “Spud” is in development, and OpenAI announced an additional $10 billion raise. Source

2. Arm Enters Chipmaking After 35 Years with an AGI CPU, Meta as Launch Customer

Arm unveiled its first proprietary processor, the AGI CPU, a 136-core chip manufactured on TSMC 3nm and targeting AI inference in data centers. The company claims 2x performance per rack versus x86 and up to $10 billion in CapEx savings per gigawatt of AI capacity. Meta co-developed the chip and signed on as the launch customer; OpenAI, Cerebras, Cloudflare, and SAP are also committed. Arm stock rose 16% on the announcement. Source

3. Anthropic Ships Claude Code Auto Mode, Reducing Manual Approval for Agentic Tasks

Anthropic released an auto mode for Claude Code in research preview for Enterprise and API users, allowing the agent to autonomously execute file writes and bash commands it classifies as safe without per-action human approval. A built-in classifier screens actions for prompt injection and destructive operations before execution. Claude Cowork separately gained the ability to remotely control Mac computers for autonomous task completion. Both features require Claude Sonnet 4.6 or Opus 4.6. Source

4. LiteLLM Suffers Supply Chain Attack via Compromised CI/CD Pipeline

LiteLLM versions 1.82.7 and 1.82.8 on PyPI were compromised by threat actor TeamPCP, who stole developer credentials through a backdoored Trivy GitHub Action in LiteLLM’s CI/CD pipeline. The malicious packages included a .pth file that auto-executed on every Python startup, exfiltrating SSH keys and cloud credentials to an attacker-controlled domain. The packages were live for approximately three hours before PyPI quarantined them. The attack is part of a broader multi-week campaign that also targeted Aqua Security and Checkmarx tooling. Source

5. Amazon Acquires Fauna Robotics, Entering the Consumer Humanoid Market

Amazon acquired Fauna Robotics, a New York-based startup founded in 2024 by former Meta and Google engineers, whose product is “Sprout,” a 3.5-foot, 50-pound bipedal humanoid priced at $50,000 and aimed at developer accessibility. The roughly 50-person team joins Amazon’s Personal Robotics Group. Terms were not disclosed. Source

6. Yann LeCun’s AMI Labs Raises $1.03B Seed Round, Largest in European History

AMI Labs, founded by Turing Award winner and former Meta chief AI scientist Yann LeCun, raised $1.03 billion in seed funding at a $3.5 billion valuation, before shipping any product. The round includes backing from NVIDIA and sets a record for European seed raises. Source
