Digest — March 5, 2026

A landmark day. GPT-5.4 officially drops with native computer use and 1M token context, FlashAttention-4 pushes GPU utilization past 70%, and the Pentagon formally labels Anthropic a supply chain risk — a first for any American company.

GPT-5.4 is officially here — OpenAI’s most capable model to date. It scores 75% on OSWorld (beating the human baseline of 72.4%), 83.3% on ARC-AGI-2 Pro, and comes with native computer use baked into the API. Context window jumps to 1M tokens.

Available in three variants: standard GPT-5.4, GPT-5.4 Thinking (extended reasoning for Plus/Pro users), and GPT-5.4 Pro via API. OpenAI claims 33% fewer factual errors per claim and 18% fewer responses containing any errors vs. GPT-5.2.

FlashAttention-4 Hits 1,605 TFLOPs/s — 71% GPU Utilization on B200 Together AI’s next-gen attention kernel achieves 1.3× faster than cuDNN 9.13 and 4× faster at long sequences. Designed for Hopper and Blackwell GPUs with fully asynchronous MMA and larger tile sizes. Published alongside Together’s first AI Native Conference.

Pentagon Formally Designates Anthropic a Supply Chain Risk The DOD sent Anthropic formal notification that it’s now designated a supply chain risk — the first time an American company has received this label. Defense contractors must certify they don’t use Anthropic products. Dario Amodei says they’ll challenge it in court.

Lightricks drops a major video model upgrade with a free desktop app, and Google turns NotebookLM into a video studio.

Major update to Lightricks’ open-source video model. The 22B-parameter DiT now ships with a completely rebuilt VAE for sharper details, improved image-to-video quality, last-frame interpolation, and native 9:16 portrait support at 24/48 FPS.

Alongside the model, Lightricks released LTX Desktop — a free local video generation app. Three model variants available: full dev (for fine-tuning), distilled (faster inference), and a LoRA adapter. Apache-2.0 licensed.
