Anthropix

Anthropix is an open-source Elixir client for the Anthropic API, providing a simple and convenient way to integrate Claude, Anthropic's powerful language model, into your applications.

• ✅ API client fully implementing the Anthropic API
• 🛠️ Tool use (function calling)
• 🛜 Streaming API requests
  • Stream to an Enumerable
  • Or stream messages to any Elixir process

Installation

The package can be installed by adding anthropix to your list of dependencies in mix.exs.

def deps do
  [
    {:anthropix, "~> 0.3"}
  ]
end

Quickstart

For more examples, refer to the Anthropix documentation.

Initiate a client.

See Anthropix.init/2.

client = Anthropix.init(api_key)

Chat with Claude

See Anthropix.chat/2.

messages = [
  %{role: "user", content: "Why is the sky blue?"},
  %{role: "assistant", content: "Due to rayleigh scattering."},
  %{role: "user", content: "How is that different than mie scattering?"},
]

Anthropix.chat(client, [
  model: "claude-3-opus-20240229",
  messages: messages,
])
# {:ok, %{"content" => [%{
#   "type" => "text",
#   "text" => "Mie scattering affects all wavelengths similarly, while Rayleigh favors shorter ones."
# }], ...}}

Streaming

A streaming request can be initiated by setting the :stream option.

When :stream is true a lazy t:Enumerable.t/0 is returned which can be used with any Stream functions.

{:ok, stream} = Anthropix.chat(client, [
  model: "claude-3-opus-20240229",
  messages: messages,
  stream: true,
])
# {:ok, #Function<52.53678557/2 in Stream.resource/3>}

stream
|> Stream.each(&update_ui_with_chunk/1)
|> Stream.run()
# :ok

Because the above approach builds the t:Enumerable.t/0 by calling receive, using this approach inside GenServer callbacks may cause the GenServer to misbehave. Setting the :stream option to a t:pid/0 returns a t:Task.t/0 which will send messages to the specified process.
