Tip: If you are using Deepseek R1 through OpenRouter and cannot see it "thinking", do this:

Install this function:

https://openwebui.com/f/roneru/openrouter_reasoning_tokens_pipe

Click on the settings gear icon next to it click custom on each parameter and add the deepseek api link and your api token:

Openrouter Api Base Url=https://openrouter.ai/api/v1 (The v1 part is important, keep that)

Openrouter Api Key=Your API Key

It will add three models to your models list and you can change that in the function code:

    def pipes(self):
        models = [
            "deepseek/deepseek-r1:free",
            "deepseek/deepseek-r1-distill-llama-70b",
            "deepseek/deepseek-r1",
        ]

The new models will begin with: openrouter_reasoning_tokens_pipe.reasoning

Configure models in the models list as you would normally:
