Indeed, that's posting before being fully awake.

OF course you can't recover any accuracy, but LLM are in fact prone to this kind of repetition no matter what, this is a known failure mode that's why samplers aimed at avoiding this have been designed over the past few years.

But it won't necessary be gibberish! even a highly quantized R1 has still much more embedded information than a 14 or even 32B model, so I don't see why it should output more gibberish than smaller models.
Another option is to employ min_p = 0.05 to force the model not to generate low prob tokens - it can help especially in the case when the 1.58bit model generates on average 1/8000 tokens or so an "incorrect" token (for eg `score := 0`)
I also tried not setting the seeds, but the results are still the same - quantizing all layers seems to make the model forget and repeat everything - I put all examples here: https://docs.unsloth.ai/basics/deepseek-r1-dynamic-1.58-bit#...
This is really interesting insight (although other works cover this as well). I am particularly amused by the process by which the authors of this blog post arrived at these particular seeds. Good work nonetheless!
