Chat with an AWS bedrock model

Source: R/provider-bedrock.R
chat_bedrock.Rd

AWS Bedrock provides a number of chat based models, including those Anthropic's Claude.

Authenthication is handled through {paws.common}, so if authenthication does not work for you automatically, you'll need to follow the advice at https://www.paws-r-sdk.com/#credentials. In particular, if your org uses AWS SSO, you'll need to run aws sso login at the terminal.

Usage

chat_bedrock(
  system_prompt = NULL,
  turns = NULL,
  model = NULL,
  profile = NULL,
  echo = NULL
)

Arguments

system_prompt

A system prompt to set the behavior of the assistant.

turns

A list of turns to start the chat with (i.e., continuing a previous conversation). If not provided, the conversation begins from scratch. Do not provide non-NULL values for both turns and system_prompt.

Each message in the list should be a named list with at least role (usually system, user, or assistant, but tool is also possible). Normally there is also a content field, which is a string.

model

The model to use for the chat. The default, NULL, will pick a reasonable default, and tell you about. We strongly recommend explicitly choosing a model for all but the most casual use.

profile

AWS profile to use.

echo

One of the following options:

  • none: don't emit any output (default when running in a function).

  • text: echo text output as it streams in (default when running at the console).

  • all: echo all input and output.

Note this only affects the chat() method.

Value

A Chat object.
