What Is LLM Inference?
LLM inference is the process of running a pre-trained large language model to generate predictions, responses, or outputs based on input data. Once a model has been trained on vast amounts of data, inference is the deployment phase where the model applies its learned knowledge to real-world tasks—such as answering questions, generating code, summarizing documents, or powering conversational AI. Efficient inference is critical for organizations seeking to deliver fast, scalable, and cost-effective AI applications. The choice of inference provider directly impacts latency, throughput, accuracy, and operational costs, making it essential to select a platform optimized for high-performance deployment of large language models.
