UK AI news: £100m AI procurement and GPT-6 Astra
UK AI news for 31 August to 6 September 2026: the £100m Sovereign AI procurement competitions open, GPT-6 Astra prices above Sol on every tier, and a consultation closes.
- The UK opened the first four competitions under the £100m Sovereign AI R&D Procurement Scheme in the week to 6 September 2026, covering NHS productivity, defence, compute efficiency and AI agent security.
- UK public sector bodies awarded 453 AI-related contracts worth £1.4bn in 2026 to August (Tussell, 2026), which puts the £100m scheme in proportion.
- GPT-6 Astra shipped on 3 September 2026 at $10 in and $50 out per million tokens: twice GPT-5.6 Sol's pre-promotional input rate, and 2.5x the promotional $4 and $20 that run to at least 21 November 2026.
