 Create a model from a GGUF file. The `files` parameter should be filled out with the file name and SHA256 digest of the GGUF file you wish to use. Use [/api/blobs/:digest](#push-a-blob) to push the GGUF file to the server before calling this API.
+For a model stored in multiple split GGUF files, includes all split GGUF files in the `files` parameter with the file names and SHA256 digests. It is recommended to provide files in split number order even though Ollama itself will sort them in order.
