             owner (str | None): Owner of this function. Typically used to know who created it.
             secrets (dict | None): Additional secrets as key/value pairs. These can e.g. password to simulators or other data sources. Keys must be lowercase characters, numbers or dashes (-) and at most 15 characters. You can create at most 30 secrets, all keys must be unique.
             env_vars (dict | None): Environment variables as key/value pairs. Keys can contain only letters, numbers or the underscore character. You can create at most 100 environment variables.
-            cpu (Number | None): Number of CPU cores per function. Allowed values are in the range [0.1, 0.6], and None translates to the API default which is 0.25 in GCP. The argument is unavailable in Azure.
-            memory (Number | None): Memory per function measured in GB. Allowed values are in the range [0.1, 2.5], and None translates to the API default which is 1 GB in GCP. The argument is unavailable in Azure.
+            cpu (Number | None): Number of CPU cores per function. Allowed range and default value are given by the `limits endpoint. <https://developer.cognite.com/api#tag/Functions/operation/functionsLimits>`_, and None translates to the API default. On Azure, only the default value is used.

Allowed range and default value are given by the `limits endpoint. <https://developer.cognite.com/api#tag/Functions/operation/functionsLimits>`_, and None translates to the API default. On Azure, only the default value is used.
             runtime (str | None): The function runtime. Valid values are ["py38", "py39", "py310", "py311", `None`], and `None` translates to the API default which will change over time. The runtime "py38" resolves to the latest version of the Python 3.8 series.
             metadata (dict | None): Metadata for the function as key/value pairs. Key & values can be at most 32, 512 characters long respectively. You can have at the most 16 key-value pairs, with a maximum size of 512 bytes.
             index_url (str | None): Index URL for Python Package Manager to use. Be aware of the intrinsic security implications of using the `index_url` option. `More information can be found on official docs, <https://docs.cognite.com/cdf/functions/#additional-arguments>`_
