What are the best providers for DS V4.1 flash? (on Openrouter)

Hey guys, I recently set up Hermes agent on my VPS, for the model I chose Deepseek V4.1 flash since it's the sweet spot of cheap and smart, but I'm struggling with choosing a good provider and sticking with it. I want to set couple of providers on the whitelist and forget about it. I wanted to use Deepseek itself, but the red warning beside it saying "this provider may use prompts for training and may retain prompt data" made me hesitate. I used Deepinfra as well, it wasn't bad, but i saw some complains about it here. All I know for sure is to put Open Inference on the blacklist and don't even look at it. If you use this model, I'd be happy to know which providers worked best for you. Thanks.
