AI Daily Brief — 22 March 2025

A genuinely quiet Saturday. xAI shipped a standalone Grok iOS app — the first time the chatbot exists independent of X — but no frontier-lab model release, paper or funding round was dated to the day. The press chewed through NVIDIA’s Tuesday keynote and Tencent’s Friday Hunyuan-T1 launch.

Top stories

  • xAI launches standalone Grok iOS app. The chatbot decoupled from X for the first time with a dedicated iOS release on Saturday. Follows xAI’s Mar 17 acquisition of Hotshot (AI video) and precedes the all-stock X/xAI merger announced Mar 28 at $33B for X. via Wikipedia

Who shipped

xAI ran solo with the standalone Grok app. Western frontier labs (OpenAI, Anthropic, Google DeepMind, Meta) all stayed off official channels for the weekend.

Quiet corners

No notable open-weights releases, arxiv landmark, or funding round dated Mar 22. The community was still digesting Mistral Small 3.1 (Mar 17), the NVIDIA GTC stack (Mar 18), Tencent Hunyuan-T1 (Mar 21), and Anthropic Claude web search (Mar 20). DeepSeek-V3-0324 was two days out.

By the numbers

  • 1 — Grok app finally divorced from X
  • 2 days — until DeepSeek-V3-0324 lands
  • Most-mentioned company: xAI
