Where did you get the range of values from? As far as I know, the temperature parameter for most models ranges from 0 to 2.

I have seen temperature values of most of the large language model ranges between 0 to 1. but after your feedback i have done some research more. i have found some useful discussion and links. but there are lots of confusion.

if we consider temperature 0 to 2 in ollama model then we need to change also in open ai models too. based on these ollama issues and discussion i found that ollama using range 0 to 2 and Ollama should divide temperature by 2 before processing the prompt. so this PR is not worth it but yes we need to adjust the open ai model parameter values and increase the temperature to range 2.

You're right, that's why we set the temperature range in our OpenAI Compatible API provider to 0-2, while OpenAI provider sets it to 0-1. We follow the official OpenAI provider's range, while other providers compatible with OpenAI API have different ranges for temperature, so we adjusted it to 0-2.

I think we need to set temperature range 0-2 in official open ai provider also.

This is the from open ai documentation.
What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

Oops, my bad, OpenAI updated the range of temperature values, I didn't notice that.
Would you mind helping me adjust the range of temperature values for OpenAI?

Sure

Hello @takatost ,

Sorry for late response, i have adjusted open ai max temperature to 2. but when i tried and asking some question it generating some wierd responses.

when i decrease the temperature below one then it will answer what i want.

and for adjusting temperature i follow this simple steps.

parameter_rules:
  - name: temperature
    use_template: temperature
    max: 2

Also for testing i update the version of openai but it will not work as expected. do you have any idea?

Yeah, we tested it too. Once the temperature goes over 1, all sorts of garbled characters start showing up. Just as expected. 😅

And, what issues might occur if updating to the latest version of OpenAI SDK?

Same issue after updating OpenAI Sdk also.
