We are training on top of llama 3. The 256k reasoning benchmarks are on the open LLM leaderboard.

And re: token count: our copy was wrong -- it's pre-prepped copy for a model run that didn't pan out. Updating to correct number -- already present in the training grid further down in the model card. Bit over 830M tokens for this stage and >1B for all extension stages combined.

Your point re: token counts still stands. We wanted to get something out asap and finetune more later. I believe the giant vocab size of llama 3 is actually adversarial for finetunes. You need a beefy dataset to even hit all vocab tokens a single time with a forward and backward.
