UK's Council for Science and Technology urges a national AI Sovereignty Plan: one accountable owner, open-weight and domestic model pilots on national compute, and a look at an open-source sovereign base model

Why it matters

【Key points】

On October 19 (09:30 UTC) gov.uk published a letter from the Council for Science and Technology (CST), the UK's top independent science advisory body, to AI Minister Kanishka Narayan: "AI sovereignty: preserving UK agency in an AI-enabled world". It is dated July 30 and copied to the PM, the Chancellor and the PM's AI Taskforce chair.

CST defines AI sovereignty as enough agency across the AI value chain to deliver the UK's chosen outcomes, keep value at home and stay resilient under duress. Without urgent action, it warns, the UK risks becoming "a high-value AI customer".

Four recommendations: (1) a UK AI Sovereignty Plan, starting with a rapid map of compute, data, skills and models to decide what to own, partner on or securely access, plus fast public-interest pilots; (2) one accountable owner, e.g. the head of the Cabinet Office AI Taskforce; (3) invest in skills, data and trust, with dataset-access trials in areas like health and creative data; (4) keep access to leading global models while building selected UK capability: pilot open-weight and smaller domestic models on national compute, and consider the Alan Turing Institute's proposal for an open-source sovereign base model trained from scratch.

【Our read】

1. Advice, not policy: written in July, published now, with no government response or funding yet.

2. The direction matters: top UK advisers now list open-weight models, domestic models and an open sovereign base model as options, not just access to US closed models.

3. Watch for a formal AI Sovereignty Plan with a named owner, and whether the Turing proposal gets compute.
