By default, {% data variables.product.prodname_copilot_short %} code completion uses the GPT 3.5 Turbo large language model (LLM). As an alternative, you can choose to use a model based on GPT 4o-mini. This model has been trained on a wide range of high quality public {% data variables.product.github %} repositories, providing coverage of over 30 programming languages. Its knowledge base is more current than the default model and you may find that it generates completion suggestions more quickly.
