feat: support for claude

[TwistingTwists]

Done so far:

• basic md_json mode support
• basic text support
• do_streaming_chat_completion/2 in anthropic.ex
• to_openai_response/1 needs to be more robust

In progress:

• vision support
• tool mode for anthropic https://docs.anthropic.com/claude/docs/functions-external-tools#function-calling-format = handle formatting request and parsing response *

Examples of using Sax parsing with Saxy (which I used recently), if that's useful!

Maybe don't need to do XML stuff. Json mode has been reported to work reliably

{"anthropic-beta", "tools-2024-04-04"} this header is required to use tools now

The function to conform to openai structure should be:

  # %{
  #   "content" => [
  #     %{
  #       "text" => "ACTUAL RESPONSE ",
  #       "type" => "text"
  #     }
  #   ],
  #   "id" => "msg_01W35ZRGGrPaL4fXqgB5fHDs",
  #   "model" => "claude-3-haiku-20240307",
  #   "role" => "assistant",
  #   "stop_reason" => "end_turn",
  #   "stop_sequence" => nil,
  #   "type" => "message",
  #   "usage" => %{"input_tokens" => 243, "output_tokens" => 132}
  # }
  defp to_openai_response(%{"content" => [%{"text" => text}]} = _params) do
    %{
      "choices" => [
        %{
          "message" => %{"content" => text}
        }
      ]
    }
  end

Added PR but removed my fork so i could submit something else to main repo, but it's still here: https://github.com/TwistingTwists/instructor_ex/pull/1/files

[TwistingTwists]

Will work on it over the weekend. Thanks for this @noozo !

[TwistingTwists]

@cigrainger : Streaming response works.

Will add an example in a few minutes. Feel free to checkout this branch.

This might not be mergable, at the moment, because it includes lots of goodies from other branches as well. But it works.

[TwistingTwists]

Big thanks to @noozo , @thbar for the tips ! :)

[TwistingTwists]

Also, since I was testing Gemini as well, I rebased Andres Alejos 's work and put this in the same PR.

can remove this if needed.

[TwistingTwists]

almost done with #33

[cigrainger]

Gave it a try and got the following error:

** (MatchError) no match of right hand side value: {:error, :adapter_error, %{"error" => %{"message" => "tool_choice: Input tag 'function' found using 'type' does not match any of the expected tags: 'auto', 'any', 'tool'", "type" => "invalid_request_error"}, "type" => "error"}}

[TwistingTwists]

@cigrainger ,{:error, error} is always a tuple of two. Also updated the signature of the chat_completion function.

[ice-cap0]

eagerly waiting for this 🎉

[TwistingTwists]

@frozencap : feel free to try it out today from git directly. Open to feedback.
