 # LLM360 Research Suite: K2 Loss Spike 1
-During the first K2 training phase, we encountered two loss spikes. This repo contains 34 checkpoints that capture the training dynamics during the loss spikes.
+We encountered two major loss spikes while training K2. 
+The first loss spike occured after X checkpoints and lasted over ~34 checkpoints. We restarted training at checkpoint X and training returned to normal. it went away, and 
+The [second loss spike](https://huggingface.co/LLM360/K2-Spike-2/) occured after restarting training to fix the first loss spike at checkpoint X and lasted from ~8 checkpoints.
+We are releasing these checkpoints so others can study this interesting phenomena in large model training.
