🛡️ HEBATRON: Hebrew-Specialized Mamba2-MoE
HEBATRON is a state-of-the-art, high-performance language model specialized for the Hebrew language. Developed through a collaboration between PwC Israel, MAFAT, and AWS, it introduces a unique hybrid architecture combining Mamba2 and Mixture-of-Experts (MoE).
🚀 Model Summary
HEBATRON is designed to handle the structural and morphological complexities of Hebrew while providing linear scaling for long-context tasks. It is a localized and enhanced version of the Nemotron-3-Nano-30B framework, optimized for native-level reasoning in Hebrew and English.

🧬 Training Curriculum
The model was trained using a three-phase Curriculum Learning strategy:
- Phase 1: Formal Foundation (75.5B tokens) Focused on high-quality, structured Hebrew (legal, academic, and literary texts) to establish core grammatical rules.
- Phase 2: Colloquial Expansion (3.36B tokens) Integration of social media, forums, and informal web data to handle slang and modern registers.
- Phase 3: Long-Context Extension (20.4B tokens) Fine-tuning on dense, long-form documents to stabilize the 64k context window.
📊 Performance Evaluation
Hebrew Reasoning Benchmarks
- SNLI (Semantic Reasoning): 91.2% accuracy
- Israeli Trivia: 72.1% (+14pt vs base)
- Hebrew Average Reasoning: 73.8% (Surpassing DictaLM-3.0-Thinking)
- GSM8K (Math): 83.3% accuracy in native Hebrew
English Reasoning Benchmarks
