AI Daily Brief — 1 April 2026

A quiet Wednesday for frontier model drops — no new flagship crossed the wire — but the morning’s big story is industrial. Oracle’s 30,000-headcount cut, announced 31 March, lands across the wires as the company pivots $50 billion toward AI infrastructure. Perplexity makes “Computer in Slack” public, Amazon Science publishes a notable TTS-robustness paper, and Last Week in AI #238 lands as the week’s recap.

Top stories

  • Oracle’s 30,000 layoffs land. Oracle terminates roughly 30,000 employees — about 18% of its 190,000-person global headcount — to free $8–10 billion in annual cash flow for AI infrastructure. The cuts hit Cerner/Oracle Health, Oracle Cloud Infrastructure and ERP consulting; the AI data-centre and Stargate buildout teams are spared. via Tech Insider
  • Perplexity ships “Computer in Slack” publicly. After several weeks of internal use, Perplexity opens Computer in Slack to all Max, Pro and Enterprise subscribers via the Slack Marketplace. Computer codes in Claude Code and GPT Codex, orchestrates 400+ connectors, and can search the web, generate content, analyse business data and build reports straight inside Slack threads. via Perplexity
  • Amazon Science — LLM-TTS robustness. Ammar Abbas publishes a research note on quality and robustness in LLM-based text-to-speech: LoRA-based locale-specific data augmentation tackles accent leakage in polyglot voices, while chain-of-thought reasoning helps combat hallucinated repetitions and unexpected cut-offs in autoregressive speech generation. via Amazon Science
  • Last Week in AI #238. The weekly recap covers GPT-5.4 mini and nano (400k context, nano API-only and pitched for high-volume classification), Mistral Small 4 (open-sourced 119B-total / 6B-active MoE) plus the new Forge for custom training, DLSS 5 as a real-time generative AI filter for games, OpenAI’s strategic pivot, and attention residuals. via Last Week in AI
