AiFail

Python Library for retrying openai/gcp API calls

Installation

pip install aifail

Usage

To get started, simply wrap your functions with @retry_if, specifying the condition to retry on.

https://github.com/GooeyAI/aifail/blob/a540c05a2a9436c0b6b1caab8ed823387999d5f9/examples/basic_openai.py#L5

Custom logic

You can use this with anything that needs retrying, e.g. google sheets -

def sheets_api_should_retry(e: Exception) -> bool:
    return isinstance(e, HttpError) and (
        e.resp.status in (408, 429) or e.resp.status > 500
    )


@retry_if(sheets_api_should_retry)
def update_cell(spreadsheet_id: str, row: int, col: int, value: str):
    get_spreadsheet_service().values().update(
        spreadsheetId=spreadsheet_id,
        range=f"{col_i2a(col)}{row}:{col_i2a(col)}{row}",
        body={"values": [[value]]},
        valueInputOption="RAW",
    ).execute()

Advanced Usage

This library is used by GooeyAI in production to handle thousands of API calls every day. To save costs and handle rate limits, you can intelligently specify quick fallbacks (eg azure openai) -

Traceable Errors

AiFail comes with a built in logger, and outputs complete stack traces tracing the error back to the original call site.
