The document summarizes a talk on live modeling given by Benoit Combemale at a LangDev meetup at Amazon. Live modeling brings immediate feedback and direct manipulation capabilities to modeling environments. It allows users to see how changes to a model impact its runtime state or execution trace. Live modeling has various uses across different domains and can enhance modeling tools. The talk explored live modeling challenges and approaches from a language engineering perspective, with the goal of integrating these capabilities into domain-specific languages.
