stablelm-4e1t-2b-v0.1

stablelm-4e1t-2b-v0.1

This is a layer pruning experiment based off of stablelm-3b-4e1t:

• 10 layers pruned with PruneMe/MergeKit
  • layers selected using BEE-spoke-data/fineweb-100k_en-med
• brief subsequent continued pretraining @ ctx 4096
  • data: 10k rows of FineWeb (different than pruning data) + some curated data
• wandb here
