LLM360 Research Suite: K2 Loss Spike 1

We encountered two major loss spikes while training K2.

The first loss spike occurred after 160 checkpoints and lasted over ~34 checkpoints. We restarted training at checkpoint 160 and training returned to normal.
The second loss spike occurred after restarting training to fix the first loss spike at checkpoint 186 and lasted from ~8 checkpoints.
For every spike checkpoint, we also uploaded the corresponding normal checkpoint for easy comparison. You could find different checkpoints in different branches.

We are releasing these checkpoints so others can study this interesting phenomena in large model training.

Purpose

Loss spikes are still a relatively unknown phenomena. By making these spikes and associated training details available, we hope others use these artifacts to further the worlds knowledge on this topic.

First 10 Checkpoints

Checkpoints
Checkpoint 160	Checkpoint 170
Checkpoint 162	Checkpoint 172
Checkpoint 164	Checkpoint 174
Checkpoint 166	Checkpoint 176
