TinyLlama-1.1B-3T-openhermes

This is the Instruction Fine Tuned version of Tiny Llama on @Teknium1's openhermes dataset.

"The TinyLlama project aims to pretrain a 1.1B Llama model on 3 trillion tokens. With some proper optimization, we can achieve this within a span of "just" 90 days using 16 A100-40G GPUs 🚀🚀. The training has started on 2023-09-01."

The model achieves the following loss:

• Loss: 1.3647

The loss exploded after a couple hundred steps. As suggested by winglian, we set the following values in the config file:

adam_epsilon: 0.00001
max_grad_norm: 1.0
