Methods, apparatus, systems, and articles of manufacture to process a machine learning model in a web-browser environment are disclosed. An example apparatus includes a graph builder to accumulate machine learning operations as a graph. A tensor manager is to, in response to a request to access a tensor that is not yet available and associated with the machine learning operations, identify the graph based on the tensor. A graph cache manager is to determine whether a condensed graph corresponding to the identified graph is available. A graph condenser is to, in response to the graph cache manager determining that the condensed graph is not available, generate the condensed graph. A graph executor is to execute the condensed graph to create the tensor. The tensor manager is to provide the tensor as a response to the request to access the tensor.
