Public prices involving UK AI Security Institute
- Administration of the UK AI Safety Institute's fund for sourcing external evaluations (programs that test frontier models' dangerous capabilities), awarded to Smarter Society
The vehicle behind AISI's evals bounty (GBP 3,000 to 15,000 per successful task, store id aisi-evals-bounty-per-successful-task). The notice does not split the administrator's fee from the money paid out to evaluation builders, so read it as the size of the sourcing programme, not a price per task.
The payer's own page, UK Contracts Finder (official API record), DSIT award notice: AISI Evaluation Sourcing Fund Administration
£2,300,000 awarded (notice value up to £5,300,000)per contract (Oct 2024 to Mar 2025)
- Private capture-the-flag evaluations designed and built to order to test an AI model's offensive cyber capabilities (UK AI Security Institute, prj_3902 WP 2)
Private (non-public) CTF environments bought by an evaluator over ten months; the count of CTFs is not stated. The supplier is written as 'Rethinks Priorities' in the notice.
The payer's own page, UK Contracts Finder (official API record), DSIT award notice: prj_3902, WP 2, Private Capture the Flag Evaluations
£545,000per contract (Dec 2024 to Sep 2025)
- Cyber range environment for an enterprise network built to order for AI agent evaluation: tasks inside it, a solver per task, an automated grader per task and human baselines, compatible with AISI's Inspect platform (SpecOps Inc for the UK AI Security Institute, WP 1)
A government buyer's published award for an environment made to its order: the requirement names one complex cyber range environment plus its tasks, solvers, graders and human baselines, so this is the nearest public figure to a per-environment price for a high-fidelity private environment. Awarded 2025-01-10 by call-off from a dynamic purchasing system, contract 2025-03-13 to 2025-04-30.
The payer's own page, UK Contracts Finder (official API record), DSIT award notice: WP 1: Cyber Range Scenarios, Enterprise Networks
£999,600per contract (Jan to Apr 2025)
- Cyber range scenarios for critical national infrastructure built to order for AI evaluation (Hack The Box for the UK AI Security Institute, Cyber Evaluations WP1)
Sister work package to the SpecOps enterprise-network range: the same buyer paid a second vendor for critical-infrastructure range scenarios. The notice does not state how many scenarios, so no per-environment figure. Awarded 2024-12-12, contract 2025-01-02 to 2025-06-30.
The payer's own page, UK Contracts Finder (official API record), DSIT award notice: Cyber Evaluations, WP1, Cyber Range Scenarios
£590,500per contract (Jan to Jun 2025)
- Development time on an evaluation task for the UK AI Safety Institute (evals bounty indication)
The rate the buyer uses to size a task bounty, paid only for tasks that succeed; stage-two applicants also get a GBP 2,000 award toward compute.

- One successful dangerous-capability or autonomous-agent evaluation task built for the UK AI Safety Institute (evals bounty)
A government evaluator buying tasks directly from builders (individuals or organisations), paid in full only once the evaluation meets its criteria; exceptional work may earn more.

- Non-public capture-the-flag scenarios and end-to-end attack exercises, plus a benchmark suite of scenarios testing whether LLM agents' safeguards can be bypassed (Grey Swan Security for the UK AI Safety Institute)
Four-month build of private agent scenarios; scenario count not stated. The supplier is named 'Grey Swan Security Inc'; the agent-safeguard benchmark work matches Gray Swan AI's line of business, but the notice alone does not confirm it is the same company.
The payer's own page, UK Contracts Finder (official API record), DSIT award notice: offensive cyber capability and agent safeguards measurement
£440,000per contract (Jun to Oct 2024)
- Suites of tasks ('evals') for evaluating AI systems, created to order (Rethink Priorities for the UK AI Safety Institute)
Twelve-week task-suite build, extended in time and value by half again (a sign that a first task order grows once the buyer sees the tasks). Task count not stated.

£232,517.64 (first awarded at £155,011.76)per contract (Jan to Mar 2024)
