SUPERSTRATEGY – probabilistically optimised, frontier-forecasted decisions.

Cassi is a Superstrategy engine that forecasts 50% more accurately than humans, combining AI and collective intelligence to improve decisions.

Media coverage

Who we are. Why we exist.

Cassi pairs collective intelligence, your team's own judgement, made legible and stripped of bias, with frontier AI forecasting. Together, they're more accurate than either alone.

In Greek myth, Cassandra could see the future perfectly. Nobody believed her.

Cassi is built to fix that curse for organisations. It tells you what you need to know, not what you want to hear.

Cassi puts numbers on the AI scenario reports everyone's talking about — every resolvable claim, priced and tracked.

64%

Leading GPU-cluster performance rises ~10× by 2028

Likelihood over time

Jul 2026Oct 2026
64%

Question: Will the performance of leading GPU clusters be at least 10× that of early-2026 leading clusters by 1 Jan 29?

Resolves: TRUE if Epoch's GPU-clusters data shows leading-cluster performance ≥10× the early-2026 leader by the date; otherwise FALSE.

Resolution date: 1 Jan 2029

Open-weight AI matches the closed frontier

Likelihood over time

Aug 2026Oct 2026
TRUERESOLVED 10 Aug 2026

Question: Will an open-weight model be within 5% of the leading closed model on a major composite capability index as of 1 Jan 31?

Resolves: Will resolve as true if, by 01 Jan 31, Artificial Analysis, Stanford HELM or a comparable independent composite evaluation places an open-weight model within 5% of the leading closed model using the same published scoring method. It will otherwise resolve as false.

Why it resolved: Artificial Analysis’ August 6, 2026 v4.1.1 update says Claude Opus 5 remains #1 on the Artificial Analysis Intelligence Index with a score of 63 (https://artificialanalysis.ai/articles/artificial-analysis-intelligence-index-v4-1-1). Artificial Analysis’ Kimi K3 comparison page states Kimi K3 scores 60 on the same Intelligence Index v4.1.1, while GPT-5.6 Sol scores 61 (https://artificialanalysis.ai/models/comparisons/kimi-k3-vs-gpt-5-6-sol). Since 60/63 = 95.24%, Kimi K3 is within 5% of the leading closed model. Moonshot’s Hugging Face repository states that full Kimi K3 model weights are released under the Kimi K3 License (https://huggingface.co/moonshotai/Kimi-K3/commit/c5d1dd4c428bd1ce8b88c5044f3b6ccde9e3b721), satisfying the open-weight condition.

TRUERESOLVED 31 Aug 2026

AI-driven care becomes mainstream in the NHS

Likelihood over time

Jul 2026Oct 2026
TRUERESOLVED 31 Aug 2026

Question: Will AI-driven diagnostics, treatment or personalised care be in mainstream, system-wide use across the NHS before 1 Jan 31?

Resolves: TRUE if NHS/DHSC reporting documents system-wide deployment of AI diagnostics/treatment/personalised care before the date; otherwise FALSE.

Why it resolved: NHS England’s official “Quality strategy for NHS-funded care in England,” published 14 July 2026, reports that an AI tool developed by Skin Analytics “is being rolled out across the NHS” to assess potentially cancerous skin lesions and recommend discharge or referral. It also reports an AI tool predicting risks such as falls and viruses is being rolled out across more than two-thirds of ICBs. These are NHS-reported AI diagnostic/care deployments beyond pilots.

At least 80% of UK businesses use autonomous AI

Likelihood over time

Aug 2026Oct 2026
9%

Question: Will at least 80% of UK businesses report using AI as of Q4 2030, with at least half of adopters delegating multi-step work without case-by-case approval?

Resolves: Will resolve as true if, by 01 Jul 31, official UK business data covering Q4 2030 show that at least 80% of businesses use AI, and an official or robust representative survey shows that at least half of adopters delegate multi-step work without case-by-case human approval. It will otherwise resolve as false.
