OpenAI API Request

Logs

You can pass custom logger and log_marks (a string or a collection of strings) to chat/completions to get input and output logging.

Timeout control

This toolkit supports client-side timeout control:

from handyllm import OpenAIAPI
prompt = [{
    "role": "user",
    "content": "please tell me a joke"
    }]
response = OpenAIAPI.chat(
    model="gpt-3.5-turbo",
    messages=prompt,
    timeout=10
    )
print(response['choices'][0]['message']['content'])

Authorization

API key and organization will be loaded using the environment variable OPENAI_API_KEY and OPENAI_ORGANIZATION, or you can set manually:

OpenAIAPI.api_key = 'sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
OpenAIAPI.organization = '......'  # default: None

Or, you can pass api_key and organization parameters in each API call.

Stream response

Stream response of chat/completions/finetunes_list_events can be achieved using steam parameter:

response = OpenAIAPI.chat(
    model="gpt-3.5-turbo",
    messages=prompt,
    timeout=10,
    stream=True
    )

# you can use this to stream the response text
for text in OpenAIAPI.stream_chat(response):
    print(text, end='')

# or you can use this to get the whole response
# for chunk in response:
#     if 'content' in chunk['choices'][0]['delta']:
#         print(chunk['choices'][0]['delta']['content'], end='')

Prompt

Prompt Conversion

PromptConverter can convert this text file prompt.txt into a structured prompt for chat API calls:

$system$
You are a helpful assistant.

$user$
Please help me merge the following two JSON documents into one.

$assistant$
Sure, please give me the two JSON documents.

$user$
{
    "item1": "It is really a good day."
}
{
    "item2": "Indeed."
}
%output_format%
%misc1%
%misc2%

from handyllm import PromptConverter
converter = PromptConverter()

# chat can be used as the message parameter for OpenAI API
chat = converter.rawfile2chat('prompt.txt')

# variables wrapped in %s can be replaced at runtime
new_chat = converter.chat_replace_variables(
    chat, 
    {
        r'%misc1%': 'Note1: do not use any bad word.',
        r'%misc2%': 'Note2: be optimistic.',
    }
)

Substitute

PromptConverter can also substitute placeholder variables like %output_format% stored in text files to make multiple prompts modular. A substitute map substitute.txt looks like this:

%output_format%
Please output a SINGLE JSON object that contains all items from the two input JSON objects.

%variable1%
Placeholder text.

%variable2%
Placeholder text.

from handyllm import PromptConverter
converter = PromptConverter()
converter.read_substitute_content('substitute.txt')  # read substitute map
chat = converter.rawfile2chat('prompt.txt')  # variables are substituted already
