chat_google_gemini {ellmer} | R Documentation |
Chat with a Google Gemini or Vertex AI model
Description
Google's AI offering is broken up into two parts: Gemini and Vertex AI. Most enterprises are likely to use Vertex AI, and individuals are likely to use Gemini.
Use google_upload()
to upload files (PDFs, images, video, audio, etc.)
Authentication
By default, chat_google_gemini()
will use Google's default application
credentials if there is no API key provided. This requires the gargle
package.
It can also pick up on viewer-based credentials on Posit Connect. This in turn requires the connectcreds package.
Usage
chat_google_gemini(
system_prompt = NULL,
base_url = "https://generativelanguage.googleapis.com/v1beta/",
api_key = NULL,
model = NULL,
params = NULL,
api_args = list(),
echo = NULL
)
chat_google_vertex(
location,
project_id,
system_prompt = NULL,
model = NULL,
params = NULL,
api_args = list(),
echo = NULL
)
models_google_gemini(
base_url = "https://generativelanguage.googleapis.com/v1beta/",
api_key = NULL
)
models_google_vertex(location, project_id)
Arguments
system_prompt |
A system prompt to set the behavior of the assistant. |
base_url |
The base URL to the endpoint; the default uses OpenAI. |
api_key |
API key to use for authentication. You generally should not supply this directly, but instead set the |
model |
The model to use for the chat (defaults to "gemini-2.0-flash").
We regularly update the default, so we strongly recommend explicitly specifying a model for anything other than casual use.
Use |
params |
Common model parameters, usually created by |
api_args |
Named list of arbitrary extra arguments appended to the body
of every chat API call. Combined with the body object generated by ellmer
with |
echo |
One of the following options:
Note this only affects the |
location |
Location, e.g. |
project_id |
Project ID. |
Value
A Chat object.
