A method for generating automated discourse data using computer-generated synthetic personas is disclosed. The method is implemented at a synthetic discourse data service executing as an API-based application within a distributed network of computers. The method includes receiving discourse input data via an API endpoint from a
client device, generating an embedding vector representation of the discourse input data using a GPU-accelerated embedding generation model, and identifying candidate computer-simulated personas from a vector
database. A subset of personas is dynamically selected based on a computed persona relevance
score derived from vector distance calculations. A discourse activation value is computed for each selected persona, determining its engagement in a simulated discourse session. A
batch processing framework instantiates an engagement subset of personas, which participate in a computer-simulated discourse session, generating synthetic discourse data stored in memory. The synthetic discourse data is selectively transmitted to a
client device via an API response.
