sumtyme.ai is an AI research lab based in London developing a proprietary zero-context continual learning architecture that autonomously constructs high-dimensional world models to identify causal directional shifts in non-stationary environments such as financial markets. Its algorithms embed foundational logic to re-derive an environment's rules in real-time, enabling autonomous modelling without training data, context graphs or retraining cycles. The lab presented its approach at Fintech Sandbox Demo Day 12 and SIAM 2026.
