TinyLlama-1.1B Chat (1 Trillion token checkpoint)
The prompt format is:
f"[INST] {prompt} [INST]"
just like Llama 2 base models.
Note that this model does not emit the end of sequence (< /s >) token well. I am working to update the fine-tuning to improve this.
The model was fine tuned using an adapted filtered Openassistant dataset here.
The base repo follows here:
TinyLlama-1.1B
https://github.com/jzhang38/TinyLlama
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.
We adopted exactly the same architecture and tokenizer as Llama 2. This means TinyLlama can be plugged and played in many open-source projects built upon Llama. Besides, TinyLlama is compact with only 1.1B parameters. This compactness allows it to cater to a multitude of applications demanding a restricted computation and memory footprint.
This Model
This is an intermediate checkpoint with 480K steps and 1007B tokens.

You will need the transformers>=4.31 Do check the TinyLlama github page for more information.
