## Model Fragility

Model fragility refers to the tendency of a quantitative model to break down or produce inaccurate results when faced with conditions outside its narrow training parameters. In financial derivatives, this often occurs when a model is built on assumptions that hold true in stable markets but collapse during periods of extreme stress or volatility.

For instance, a model might assume constant liquidity, but when a systemic event triggers a liquidity crunch, the model's predictions become useless. Cryptocurrency markets are particularly prone to model fragility due to the rapid evolution of protocol incentives and the prevalence of leverage-driven feedback loops.

A fragile model may perform well for extended periods, providing a false sense of security, before failing catastrophically when the market environment shifts. To reduce fragility, developers must incorporate safety buffers, adaptive parameters, and stress testing that simulates worst-case scenarios, ensuring the model remains functional under duress.
