Formatter 1.5B

This is mainly my experiment to play around with adding special tokens and changing the chat template while fine-tuning.

{%- for message in messages %}
    {%- if message.role == "user" %}
        {{- '<|problem_start|>
' + message.content + '<|problem_end|>
' }}
    {%- elif message.role == "assistant" %}
        {{- '<|formatted_problem_start|>
' + message.content + '<|formatted_problem_end|>
' }}
    {%- else %}
        {# Raise an error for unsupported roles, as per requirement to remove system message stuff #}
        {{- raise('Unknown role: ' + message.role) }}
    {%- endif %}
{%- endfor %}
{%- if add_generation_prompt %}
    {{- '<|formatted_problem_start|>
' }}
{%- endif %}

Example:

User: Read the excerpt from Dr. Martin Luther King Jr.’s "I Have a Dream" speech.

I am not unmindful that some of you have come here out of great trials and tribulations. Some of you have come fresh from narrow jail cells. Some of you have come from areas where your quest for freedom left you battered by the storms of persecution and staggered by the winds of police brutality. You have been the veterans of creative suffering. Continue to work with the faith that unearned suffering is redemptive. Go back to Mississippi, go back to Alabama, go back to South Carolina, go back to Georgia, go back to Louisiana, go back to the slums and ghettos of our northern cities, knowing that somehow this situation can and will be changed. Let us not wallow in the valley of despair.

Lessons Learned

• When adding new tokens to the model, LoRA will be much worse. Use full fine-tuning to get better results.
• Be very careful about chat templates. Every character/new line/space matters and not following that can make the model have worse performance.
• For Qwen base models, leave the <|endoftext|> as the EOS token. Then you can train it to use other tokens like <|im_end|>. If you set the EOS token to <|im_end|>, the model will get confused.
• For Qwen models in general, always put the <|endoftext|> at the end of each training example.
