Cosine is building frontier model intelligence. Our models have topped public benchmarks for two consecutive years, outperforming OpenAI, Anthropic, Mistral, and DeepSeek. We are also Britains sovereign AI frontier lab. Selected by the UK government for its £500m Sovereign AI programme, we are the first company to train, own, and deploy a fully sovereign AI model entirely on UK soil with access to the Isambard-AI supercomputer. Cosine can be deployed air-gapped and on-premise for defence, national security, and critical infrastructure, where foreign AI is legally off the table.
