Chat with a model hosted on CloudFlare

Cloudflare works AI hosts a variety of open-source AI models. To use the Cloudflare API, you must have an Account ID and an Access Token, which you can obtain by following these instructions.

Known limitations

• Tool calling does not appear to work.

• Images don't appear to work.

Usage

chat_cloudflare(
  account = cloudflare_account(),
  system_prompt = NULL,
  params = NULL,
  api_key = cloudflare_key(),
  model = NULL,
  api_args = list(),
  echo = NULL
)

Arguments

account

The Cloudflare account ID. Taken from the CLOUDFLARE_ACCOUNT_ID env var, if defined.

system_prompt

A system prompt to set the behavior of the assistant.

params

Common model parameters, usually created by params().

api_key

The API key to use for authentication. You generally should not supply this directly, but instead set the HUGGINGFACE_API_KEY environment variable.

model

The model to use for the chat (defaults to "meta-llama/Llama-3.3-70b-instruct-fp8-fast"). We regularly update the default, so we strongly recommend explicitly specifying a model for anything other than casual use.

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 modifyList().

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.
