Nalandadata builds high-quality, curriculum-aligned data sourced from S. Chand — India's largest academic textbook publisher — spanning all subjects, grade levels, and major Indic languages alongside English. Textbook content is structured, expert-authored, and verified, which makes it valuable far beyond education: reasoning chains, scientific diagrams, structured tables, and multilingual content that transfer directly to general-purpose model training and evaluation.

Datasets

Dataset What it is
NalandaJEENEETBench 116,831 JEE & NEET questions with verified answers + worked solutions. RLVR-ready ground truth.
nalanda-image-qa 22,000+ scientific image Q&A pairs from NCERT diagrams (physics, chemistry, biology).
DrishtiTable 1,421 annotated tables for document AI / table structure recognition — with a full TEDS benchmark + leaderboard.

Models

Model Result
nalanda-qwen-7b-grpo Qwen-7B + GRPO on NalandaJEENEETBench: +6.3pp (vs −16pp for naive SFT) — verified answers make RLVR work.
nalanda-image-vl Multimodal diagram understanding: +9.3pp over zero-shot.
DrishtiTable-Qwen2.5-VL-7B Table recognition at 83.2% TEDS — beats GPT-4o on our benchmark.

Benchmark & demos

✅ Why it works

  • Verified ground truth → every JEE/NEET item has a checkable answer, enabling RLVR / GRPO pipelines that actually improve capability.
  • Expert-authored, structured source → reasoning chains, diagrams, and tables, not scraped web noise.
  • Multilingual, curriculum-aligned → English + major Indic languages across all grade levels.
