TinyLLaMA OpenHermes2.5 [Work in Progress] (Quantized)

This a finetune of TinyLLaMA base model finetuned on OpenHermes 2.5 and UltraChat 200k for a single epoch.

Training was generously supported by Jarvislabs.ai.

If you appreciate this work and would like to support its continued development, consider buying me a coffee. Your support is invaluable and greatly appreciated.
