One drawback of generative language models, e.g. large language models (LLMs), is their tendency to “hallucinate”. To address at least this technical problem of hallucination, in some examples, an input may be classified to determine a category associated with the input. In some examples, the input may be an image. A grammar may be obtained based on the determined category. The grammar may define valid sequences of symbols describing attributes of the category. A generative language model may be used to generate a sequence of symbols describing one or more attributes associated with the input. The sequence may be based on the input and conform to the grammar. In some examples, the generative language model may be an LLM.
