Chatgpt api responses different in diffrerent api keys

I have developed a langchain summarization using chatgpt api 3.5 turbo , when i use different type of keys for the summrization the structre of the summary is changing. how can i short out this problem ?

What temperature are you using? A temperature of 0 gives the most consistent responses between requests.

i use tempreture as 0 but still my responses are getting different when using different type of apis

Did you originally mean to say models? Or API keys?

Different API keys ( I used Different type of Azure Open AI APIs)
