 ## Limitations
 
 * **Small model size** – 135M parameters are an order of magnitude smaller than current frontier models.
-* **Limited world knowledge** – pre‑trained on only 15 B tokens; it lacks the broad coverage of larger models.
 * **Hallucinates frequently** – when asked questions beyond simple greetings or self‑description, it may invent plausible‑sounding but incorrect answers.
 * **Repetitive loops** – may occasionally repeat phrases or get stuck in loops, especially with low temperature sampling.
 * **Instruction coverage** – fine‑tuned on only 1 500 identity examples; it may not handle out‑of‑domain requests gracefully.
