Adoption NVIDIA puts megawatt figures behind running AI clusters below full power NVIDIA has published operating figures for capping GPU power across a cluster, including a megawatt shed in under a minute. Vendor numbers, but unusually specific ones. Infrastructure Research A proof about what shallow transformers cannot compute An IBM Research team has proved that constant-depth transformers and diffusion language models cannot match shallow quantum circuits on two specific tasks. Research Adoption A children’s hospital moves cardiac device simulation from overnight to near real time CHOP says open-source cardiac simulation now runs fast enough for routine planning, though the timings come from a vendor write-up and no outcome data has been published. Applications Research OpenAI sets out how it will disclose model misalignment, and publishes six cases OpenAI has published a standing process for investigating and disclosing misaligned model behaviour, together with six cases observed over the past six months. Policy · Research Adoption Perplexity brings its local-first Portable Computer to Windows Perplexity’s on-device agent now runs on Windows, but it needs an RTX GPU with at least 24GB of, a floor well above a typical consumer machine. Applications Research An AI agent scoring 77% on average solves only 53% of tasks every time IBM Research puts a figure on agent flakiness: an agent scoring 77.4% averaged across five runs completed only 53.0% of tasks on all five, and a diagnostic tool… Research Invention MLPerf Inference v6.1 adds RAG and agentic tests as Rubin arrives in preview MLPerf’s latest round adds retrieval-augmented generation and edge agentic benchmarks and sets a participation record, but Nvidia’s Rubin silicon appears in the preview category rather than as shipping… Hardware Policy US federal judiciary’s AI task force prepares dozens of recommendations for courts A task force led by Judge Sidney Thomas has drafted recommendations on court AI use, with final guidance possible by the end of 2026.

Strategy

America’s AI Action Plan (July 2025) sets out 90+ federal actions on innovation, infrastructure and diplomacy. The Genesis Mission for AI in science has $5bn+ in federal commitments across 278 projects (July 2026).

Regulation

No federal AI law. Executive Order 14365 (Dec 2025) set up a DOJ task force to challenge state AI laws. California’s SB 53 on frontier-model transparency has applied since 1 Jan 2026; Colorado replaced its AI Act with a narrower law from 1 Jan 2027.

Compute

Stargate targets 9+ GW across seven US sites by 2029, with Abilene, Texas the first live site (Epoch AI). Nvidia H200 exports to China have been licensed case by case since January 2026.

Key labs

OpenAI, Anthropic, Google DeepMind, Meta, xAI, Microsoft, Nvidia.

Notable models

Every frontier release is tracked on Model releases; the September 2026 flagships are GPT-6, Claude Opus 5.5, Gemini 3.8 and Grok 4.7.

What to watch

The first DOJ lawsuit against a state AI law; SB 53’s first year of enforcement; whether the Abilene site reaches 1.2 GW in Q4 2026.
