An embodiment relates to an artificial intelligence inference apparatus and method. The embodiment provides an artificial intelligence inference method, and may include converting an application based on a previously learned neural network into executable code in a high-level language independent of a learning framework, separating the executable code into General-Purpose Language (GPL) code and Domain-Specific Language (DSL) code depending on whether an acceleration operation is required, and generating target code optimized for hardware from the separated GPL code and DSL code.
