function_call APIのパラメータタイプについて調べてみた

OpenAIのAPIで、fucntion_callが発表されました。英語が苦手なのでドキュメントを読んでも手探り状態です。一番悩んだのがfunctionの引数の指定の仕方です。 JSON Schemaで指定するらしいんですけど？ https://json-schema.org/

実際にどうなるか、テストコードで調べて見ました。結果から推測するには、typeに指定できるのは下記っぽい

string
number
integer
boolean
object

うーん？スキーマとしては配列もいけそうな気がしたのだが・・・・

テスト用コードです

import openai
import json

def submit(data):
    messages = [{"role": "user", "content": data["mesg"]}]
    functions = [
        {
            "name": data["func_name"],
            "description": data["func_description"],
            "parameters": {
                "type": "object",
                "properties": {
                    data["prop_name"]: {
                        "type": data["prop_type"],
                        "description": data["prop_descriptoin"],
                    }
                },
                "required": [data["required"]],
            },
        }
    ]
    try:
        response = openai.ChatCompletion.create(
            model="gpt-3.5-turbo-0613",
            messages=messages,
            functions=functions,
            function_call="auto",
        )
        #print( response )
        return response.choices[0].message.content
    except Exception as ex:
        return ex.args

data={}
data["mesg"] = 'hello'
data["func_name"] = 'b'
data["func_description"] = "c"
data["prop_name"] = 'd'
data["prop_type"] = 'string'
data["prop_descriptoin"] = 'e'
data["required"] = 'f'

print( "{:16s} {}".format("type","output"))
for t in ['askdfja','string','String','integer','number','number[]','float','float{}','{}','[]','double','bool','boolean','dictionary','array','array of string','object','オブジェクト','文字列','文字','{"aaa":"bbb"}','[string]','string,number,boolean']:
    data["prop_type"] = t
    print( "{:16s} {}".format(t,submit(data)))

実行結果、こうなりましたよ
