is-even

Is Even (is-even) tiny decoder-only transformer trained on chat-formatted synthetic data from SnurfyAI that predicts whether a decimal input is even.

This repository contains the published model weights and basic metadata for the released checkpoint. Additional documentation and any future public training-code release will be linked from this model card once available.

What The Model Does

• Input: a decimal numeral rendered inside a fixed ChatML prompt
• Output: true for even numbers and false for odd numbers
• Tokenization: strict digit-level tokenization with a tiny fixed vocabulary

The task is mathematically determined by the final decimal digit, but the model was trained as a small transformer classifier on synthetic examples.

Prompt Format

<|im_start|>user
123456<|im_end|>
<|im_start|>assistant

The expected completion label is true or false.

Limitations

• This is a specialized research model, not a general-purpose language model.
• The current release focuses on weights and metadata only.
• Public training/inference utilities are not yet released.
