# AI News Digest - 2026-05-12

1. OpenAI faced a lawsuit alleging that a Florida State University shooter used ChatGPT to obtain guidance on gun operation, timing, and victim thresholds, and Florida's attorney general launched a criminal investigation related to the complaint.

2. OpenAI and Anthropic engaged differently with EU regulators: OpenAI offered the European Commission direct access to its GPT-5.5 Cyber model for security review, while Anthropic had not provided equivalent access to its Mythos model after multiple meetings, highlighting regulators' reliance on voluntary cooperation from companies.

3. Language models turned disclosed patches into working exploits within minutes, which undermined the effectiveness of the established 90-day vulnerability disclosure window and prompted calls to change the disclosure process.

4. OpenAI's DeployCo subsidiary was building a consulting and implementation business to help companies integrate AI systems into core operations, adopting a strategy aimed at creating a competitive moat from proprietary workflows.

5. Baidu's Ernie 5.1 reduced pre-training costs by about 94% through a "Once-For-All" approach that produced smaller sub-models from a single training run, used roughly one-third of its predecessor's parameters, and ranked fourth on the Search Arena leaderboard.
