# Configuring the number of textual-ml workers The `TEXTUAL_ML_WORKERS` environment variable specifies the number of workers to use within the `textual-ml` container. The default value is 1. Having multiple workers allows for parallelization of inferences with NER models. The number of required workers is also affected by the [number of jobs that each worker can run simultaneously](https://docs.tonic.ai/textual/textual-install-administer/configuring-textual/general-instance-and-processing-settings/config-processing-parallelism). When you deploy Textual with Kubernetes on GPUs, parallelization allows the `textual-ml` container to fully utilize the GPU. We recommend 3GB of GPU RAM for each worker. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.tonic.ai/textual/textual-install-administer/configuring-textual/general-instance-and-processing-settings/textual-config-ml-worker-count.md?ask= ``` The question should be specific, self-contained, and written in natural language.
