AI Daily Brief — 25 September 2025

Thursday packed three landmark items into a single news cycle. Judge William Alsup granted preliminary approval to the $1.5B Bartz v. Anthropic settlement — the largest copyright settlement in US history, covering ~500,000 pirated books at ~$3,000 per work, with a final fairness hearing set for April 2026. President Trump signed the TikTok executive order spinning US operations into a ~80% American consortium (Oracle, Silver Lake, Larry Ellison, Rupert Murdoch, Michael Dell) with ByteDance under 20% and Oracle as security provider. OpenAI launched ChatGPT Pulse for Pro mobile users — proactive 5–10 morning brief cards. And in a quiet but consequential procurement move, the GSA OneGov deal made Grok 4 and Grok 4 Fast available to every US federal agency for $0.42 per agency through March 2027.

Who shipped

OpenAI shipped ChatGPT Pulse. Google shipped the Gemini 2.5 Flash and Flash-Lite update. xAI didn’t ship a model but won the federal procurement of the year via GSA. Anthropic stayed quiet — Claude Sonnet 4.5 was queued for the following Monday. Meta and DeepSeek stayed quiet.

Open-source pulse

No major open-source releases Thursday. DeepSeek V3.1-Terminus (Sep 22) and Qwen3-Omni (Sep 22) plus the Apsara Qwen3-Max family (Sep 24) continued their rollout through serverless providers — the Chinese open-source week kept echoing without new launches.

Money, infra & hardware

The GSA-xAI OneGov deal was the day’s structural story — bringing Grok 4 to every federal agency for token-priced economics. NVIDIA-Intel $5B from Sep 18 continued to drive market coverage on Sep 25 as analysts weighed UALink (AMD/Broadcom) implications. No new fundraises disclosed Thursday.

Quiet corners
