# AI News Digest - 2026-03-23

1. OpenAI planned to nearly double its workforce to 8,000 by the end of 2026 as part of a major push into enterprise AI.

2. Elon Musk announced plans to build a Terafab chip plant in Austin, Texas, to produce chips at scale for robotics, artificial intelligence, and space-based data centers operated by Tesla and SpaceX.

3. Xiaomi launched three in-house MiMo AI models intended to power autonomous agents, robot control, and voice applications.

4. A German research team developed a Transformer architecture that allowed models to decide dynamically how many reasoning steps to take and combined that approach with additional memory, and the method outperformed larger models on mathematical problems.

5. OpenAI published a prompting playbook for GPT-5.4 that explained techniques for front-end designers to obtain improved website and app designs and to prevent the model from reverting to generic outputs.
