In ollama api user can define advanced parameters:

- `truncate`: truncates the end of each input to fit within context length. Returns error if `false` and context length is exceeded. Defaults to `true`
- `options`: additional model parameters listed in the documentation for the [Modelfile](https://github.com/ollama/ollama/blob/a1b74d513b8c975c3e0d931d4f0115955bbb1395/docs/modelfile.md#valid-parameters-and-values) such as `temperature`
- `keep_alive`: controls how long the model will stay loaded into memory following the request (default: `5m`)
- `dimensions`: number of dimensions for the embedding

I mostly look forward to the “dimensions” option, but it would be great to be able to use all the options.
