<h1 align="center"><font color="red">tinyllama-colorist-lora-v0.3</font></h1>

This model, tinyllama-colorist-lora-v0.3, is a fine-tuned version of TinyLlama/TinyLlama-1.1B-Chat-v0.3 on the color dataset.

<font color="yellow">Study Motivation</font>

To study this new TinyLlama model as a replacement for Llama2 for resource-constrained environment. Also, in the future I will perform the Fine-Tuning of this model for Chat and for a specific domain in Portuguese and Spanish 🤗.

<font color="yellow">Prompt format</font>

The model training process is similar to the regular Llama2 model with a chat prompt format like this:

<|im_start|>user\n{question}<|im_end|>\n<|im_start|>assistant\n{answer}<|im_end|>\n

<font color="yellow">Instructions for use</font>

User Input: Give me a sky blue color.
LLM response: #6092ff
