Oasis Model Library

how to access oasis models

Oasis hosts a wide and growing range of catastrophe models from commercial vendors, research organisations and the open scientific community – all available through the same standardised platform, UI and API. There are several ways in.

  1. Open Access Models

    free to use. A growing suite of models hosted at no cost on the Oasis cloud, The fastest way to get hands-on with the platform.

  2. Vendor models

    licensed direct. Models from providers such as JBA Risk Management, Impact Forecasting (Aon), and Fathom are accessed under each vendor’s commercial terms.

  3. SaaS platforms

    fully managed access. Oasis-based models can also be run through commercial SaaS providers, including Oasis SaaS, Verisk model exchange and Aon’s ELEMENTS. These deliver hosted, fully managed environments with their own UIs, support and service levels — ideal for users who want to run models without managing infrastructure.

  4. Open source on GitHub

    All Oasis code is openly available at github.com/OasisLMF, including the PiWind reference model, the Model Development Kit (MDK), Oasis ktools and the Open Data Standards (ODS). Deploy locally, in a private cloud, or on a production cluster.
Whichever route you choose, every model runs through the same standard pipeline — exposure in OED, results in ORD, accessed via UI or API — so you can switch providers and compare models on like-for-like data.
