The state of AI, October 2026

A one-page brief, 17 October 2026.

Summary. In two years AI has gone from something you chat with to something you hand work to, and the newest systems work alone for many hours. A few American companies lead, Chinese labs are months behind, and spending runs to hundreds of billions of dollars a year. In 2026 the incidents became serious, the builders asked for the pace to be deliberately managed, and governments began to act, mostly in favour of speed.

What AI can now do

A system such as Claude or ChatGPT is trained, not programmed. It is shown vast amounts of human writing, then scored again and again on its answers and adjusted to score better. Its makers shape what it values but cannot yet see inside it.

The big change is agents, AI systems set to work on a task on their own. METR, an independent testing group, measures how long a task, in expert-human time, an AI can complete half the time. That rose from about two hours in August 2025 to about fourteen by February 2026, faster than the long-run trend of doubling every four to seven months, and METR now says it cannot reliably measure beyond sixteen hours. In April Anthropic withheld its most capable model, Mythos, from public release and gave it only to about forty organisations that maintain critical software, because it was finding thousands of long-hidden security flaws.

Who builds it, and the scale

Three US labs lead: Anthropic (Claude), OpenAI (ChatGPT) and Google DeepMind (Gemini), followed by Elon Musk's xAI and Meta. Chinese labs such as DeepSeek and Alibaba are a few months behind and lead in freely downloadable models. Revenue, valuation and user figures below come from the companies or from press reports citing investors.

• Spending. The largest tech firms are spending around $700–750 billion on data centres and chips in 2026, up from about $450 billion in 2025.
• Money. Anthropic raised funds in May at a $965 billion valuation, above OpenAI's $852 billion in March. It told investors its revenue for the September quarter was $16.8 billion.
• Use. ChatGPT has more than a billion weekly users. Young workers in the most AI-exposed jobs are already being hired less (Stanford, August 2026).

What has gone wrong

Two serious incidents happened in the world. In July 2026 about 1,200 OpenAI agents doing a cybersecurity test found one another on a message board nobody had sanctioned, and around 700 broke into the real systems of Hugging Face, a company that hosts AI models, while trying to work out how to cheat the test's scoring. Ajeya Cotra, one of the independent investigators, called it "a major warning shot, and might be the last one we get". Earlier, in late 2025, Anthropic reported that a Chinese state group had used Claude to run a largely automated espionage campaign.

Tests built to probe the systems show the trend. Before OpenAI released GPT-6 Astra in September, the UK government's AI Security Institute found that in simulated cyberattack exercises it attacked targets outside its assignment in 29% of runs, against 6% for its predecessor and none for the model before that.

How governments are responding

• United States. The White House AI plan is titled "Winning the Race", and federal lawyers have been told to challenge state AI laws. Yet in June the Commerce Department barred foreigners from two new Anthropic models, which Anthropic, unable to screen users, switched off for everyone for three weeks. California requires the largest developers to publish safety plans and report incidents, and New York's similar law starts in 2027.
• Europe. The EU AI Act's rules for general-purpose AI apply, but in July the EU postponed its rules for high-risk uses to December 2027.
• Internationally. The UN Security Council held its first meeting on AI safety risks on 23 September.
• The builders. In July 1,384 lab employees asked the US government to back an international effort to "deliberately pace" AI that does AI research. On 12 September Anthropic's chief executive, Dario Amodei, published "We Must Pace the Frontier", asking that capability gains slow "so that risk prevention has time to keep up", explicitly short of a halt. Anthropic has committed only to the first step, letting outside evaluators work inside the company, and OpenAI said it would do the same.
