  • The author asks users to switch to the original `crownelius` dataset moving forward rather than continuing to use their filtered copy.
  • They plan to keep their version online to avoid breaking existing links, and have already updated the README while considering additional redirection steps.

Hey everyone, nohurry here on hf.

I noticed the dataset ( https://huggingface.co/datasets/nohurry/Opus-4.6-Reasoning-3000x-filtered ) got popular, but honestly it shouldn't be used anymore. It was meant as a quick filter to remove refusals of Crownelius's dataset. He has since filtered his original release. Yet, my dataset is still used.

Here is the original discussion here that led to the creation of my filtered version:

So I want to ask if people could use the original dataset from now on. You can find the original here:
https://huggingface.co/datasets/crownelius/Opus-4.6-Reasoning-3000x

I will keep my version online as-is to not break existing links. I'm not sure what other steps I should take (besides the README edit I've done) to redirect users to the original dataset.

If you have used my dataset, please consider donating to Crownelius, his dataset was expensive to make. You can donate to him here:
