# Jamba-Open-Hermes
<img src="https://cdn-uploads.huggingface.co/production/uploads/64740cf7485a7c8e1bd51ac9/Ph6ZvxwF7a0m_B5Su_EK7.webp" width="500" height="500">
# This is highly experimental and should be viewed as purely testing right now. Jamba has been very hard to train but I wanted to see how it did on one of the best datasets we have access to. I believe in transparent development so all *best* working iterations, even if they are a bit wonky, will be pushed here.

# New training underway! Thanks to the generous insights provided by **lightblue/Jamba-v0.1-chat-multilingual**, the new training is going much better. We should hopefully have a decently trained Jamaba-Open-Hermes model for general use and experimentation.
*There's been limited testing so no example outputs yet*

## Training
### Open-Hermes-2.0 (Only first 1500 examples): **[ 1530/125193 4:46:45 < 386:48:08, 0.09 it/s, Epoch 0.01/1]**
**Notes:**
- Tried over 30+ combinations of hyperparameters. Below are the best I could land on.
- Loss hovered around ~5-6 no matter what I tried with the learning rate.
- Couldn't increase batch size due to Colab limitations, so the answer may lie somewhere in a perfect balance of Lr and Batch Size.
### Hyperparameters
