A single-GPU recipe (RTX 3090 Ti):
The digit-level tokenizer is what gives Isabel-50M the highest arithmetic score in its size class.
| Type | Decoder-only transformer |
| Hidden size | 512 |
| Layers | 9 |
| Heads | 8 |
| Vocab | 32,000 (our own digit-level byte-level BPE) |
| Context | 1024 |
| Benchmark | Isabel-50M |
|---|---|
| HellaSwag (acc_norm) | 27.1 |
| ARC-Easy (acc_norm) | 43.8 |
| ARC-Challenge (acc_norm) | 23.5 |
| PIQA (acc_norm) | 57.3 |
| ArithMark-2 (acc) | 42.4 |
| Average | 40.1 |
Other same-size models and their scores are taken from the public small-model leaderboard. Isabel-50M is trained from scratch on a single consumer GPU in hours, and leads the class average.
| Model | Params | Avg | HellaSwag | ARC-E | ARC-C | PIQA | Arith |
|---|---|---|---|---|---|---|---|
| Isabel-50M | ~54M | 40.1 | 27.1 | 43.8 | 23.5 | 57.3 | 42.4 |
| Supra-1.5-50M-base-exp | 51.8M | 39.0 |
Isabel-50M leads the class on average and has the highest arithmetic score, driven by its digit-level tokenizer. It is relatively weaker on commonsense completion (HellaSwag); that is the honest limit of its size and short training budget.
