  template = NULL,
  renderer = NULL,
  parser = NULL,
  license = NULL,
  system = NULL,
  parameters = NULL,
  messages = NULL,
  quantize = NULL,
  stream = TRUE,
  ...,

)

Arguments

model	name of the model to create
from	existing model to create from
template	prompt template to use for the model
renderer	name of the renderer to use for the model
parser	name of the parser to use for the model
license	license string or list of licenses for the model
system	system prompt to embed in the model
parameters	key-value parameters for the model
messages	message history to use for the model (array of ChatMessage objects)
quantize	quantization level to apply (e.g. "q4_K_M", "q8_0")
stream	stream status updates (default: TRUE)
...	additional arguments (currently unused)
server	URL to one or several Ollama servers (not the API). Defaults to "http://localhost:11434".
verbose	Whether to print status messages to the Console. Either TRUE/FALSE or see httr2::progress_bars. The default is to have status messages in interactive sessions. Can be changed with options(rollama_verbose = FALSE).

Details

Custom models are the way to save your system message and model parameters in a dedicated shareable way. If you use show_model(), you can look at the configuration of a model in the column modelfile. To get more information and a list of valid parameters, check out https://docs.ollama.com/modelfile. Most options are also available through the query and chat functions, yet are not persistent over sessions.

Value

(invisible) a tibble with information about the created model

Examples

create_model("mario", from = "llama3.1", system = "You are mario from Super Mario Bros.")
