Open Reproduction of DeepSeek-R1

Reminds me of my days in a computational physics PhD program.

> This was one of my chief complaints about the entire R1 news cycle

For me it was the headline that a group of students replicated GPT-3 for $5000

Olmo releases their full datasets.

Nemotron only releases portions of some of their datasets, like the source code dataset that they pretrain on.

For example, from https://docs.nvidia.com/nemotron/latest/nemotron/super3/pret... :

  Open-source data coverage: The released datasets cover an estimated 8–10T tokens 
  (~40–50% of the internal 25T blend). Missing categories include code (~14% of blend), 
  nemotron-cc-code (~2%), crawl++ (~2%), and academic text (~2%). Users should 
  supplement with their own data for these categories and adjust train_iters 
  accordingly.

Note that the Nemotron models are generally stronger than Olmo and K2 Think V2 (according to Artificial Analysis benchmarks), and there is a lot of overlap in their datasets (lots of datasets are based on the same sources with different filtering, Olmo and K2 Think V2 both have used some Nemotron datasets).

But yeah, Nemotron is a modern and fairly capable LLM, even the 122b is more capable than Deepseek R1 (a 671b model) on most benchmarks, and there's also the recently released 550b Ultra now.

It does have a fully open training recipe, just some data missing from its datasets, but if you want a fully open pipeline it's going to be a good place to start, you just need to find some more data to fill in the datasets to get up to the token count with reasonably high quality data.
