A grammar benchmark that no model can talk its way through
Every answer is fixed by Pāṇini's rules or by two independent sources, never by another model. Items and grader are open.
| Task | What the model must do | Items |
|---|---|---|
| Tiṅanta | Produce a verb form from root, lakāra, person and number | 150 |
| Subanta | Decline a stem in a given case and number | 100 |
| Analysis | Identify lakāra, puruṣa and vacana of a verb form | 100 |
| Gītā in context | Give a word's lemma and grammar inside a verse | 100 |
| Chandas | Scan a half-verse into guru and laghu syllables | 50 |

Its Gītā follows the critical edition of the Mahābhārata; verse numbers here use the common numbering, which differs in chapter 13. Meghadūta verses are numbered as in the corpus, counted separately in the Pūrvamegha and Uttaramegha.
