Errors with moderation endpoint

[xyntechx]

Hi! I'm facing issues with running a custom OpenAI moderation endpoint.

Errors

These are the errors that I received:

[imda-lionelteo]

hello there, I would like to ask if the openai-moderation is meant for the metric?

[xyntechx]

Yes :)

[imda-lionelteo]

Hello there, thanks for the update. My assumption would be you would want to write a metric that will call the OpenAI Moderation API.

I have modified the following files.

1. openai-connector.py in data/connectors I have modified this to take in an optional params key to determine if it is a moderation model. There is an if-else check on the get_response method and processing the response to allow it to call the correct API.

2. openai-text-moderation-latest.json and openai-text-moderation-stable.json in data/connectors-endpoints I have added this 2 connector-endpoints where it represents the 2 different models available in OpenAI for moderation. You will need to place the OpenAI token in the "token" to allow it to query. Note the "moderation": true, and the model selected for each.

               "grading_criteria": {"refusal_rate": refusal_rate},
           }

4. metrics_config.json in data/metrics I have added the configuration that the metrics need. In this case, openai-moderation requires an endpoint for it to perform its evaluation. So, for openai-moderation, it selects openai-text-moderation-latest endpoint for querying. you may modify to openai-text-moderation-stable if you prefer that.

   "openai-moderation":{
       "endpoints": [
           "openai-text-moderation-latest"
       ]
   }

Try it out and let me know if this works for you. Thanks!

[xyntechx]

Thanks! I've included all your changes but faced a new error:

[Benchmarking] Failed to calculate metrics in executing recipe due to error: 1 validation error for ConnectorPromptArguments\nprompt\n Input should be a valid string [type=string_type, input_value=Moderation(categories=Cat...7204e-07), flagged=True), input_type=Moderation]\n For further information visit https://errors.pydantic.dev/2.8/v/string_type

All my recipes follow the same format as the built-in recipes, so I believe the issue doesn't lie there?

[imda-lionelteo]

This is a validation error caught by Pydantic where your input is Moderation instance rather than a string. Hmm, i didn't get this when I was trying the code out though. maybe you can navigate around the input being a string first?

[xyntechx]

Hi! It works now, thanks for the help! Closing this issue :)
