Original GitHub issue: https://github.com/ollama/ollama/issues/8514

What is the issue?

PS C:\Projects\project> ollama cp llama3.1 project
copied 'llama3.1' to 'project'
PS C:\Projects\project> ollama create project -f modelfile
gathering model components 
Error: unknown parameter 'tfs_z'

By specifying the tfs_z parameter in Modelfile I get an error that this parameter is unknown, however in previous versions of ollama (<0.5.0) it worked stably.

This parameter appears in the documentation https://github.com/ollama/ollama/blob/main/docs/modelfile.md, but creating a model with it is impossible.
