Some aspects relate to technologies for leveraging model output from a generative model to perform item retrieval on a listing platform. In some examples, input for item retrieval is provided to a generative model to produce a model output. A lookup is performed on a key-value store using the model output. If a matching query is found in the key-value store, a query embedding corresponding to the matching query is returned. If a matching query is not found, a query embedding is obtained by generating the query embedding from the model output or using the model output to query a known query index for a known query, which is used to lookup a query embedding in the key-value store. One or more item embeddings are identified based on the query embedding. An output is provided identifying one or more item listings corresponding to the one or more item embeddings.
