How to best use DeepSeek completion without think tags in output?

[aiwalter]

I would like to use DeepSeek via Azure but I cant find a stable way to get the output without the <think> bla bla <\think> tags in the output. Regex parsing seems not to be stable as sometimes the actual answer is inside the thinking and sometimes after. Does anyone have a good prompt for this? Seems DeepSeek model does not have a parameter to control this.
