A bilingual (English/Chinese) small language model trained entirely on **Huawei Ascend** NPU ecosystem.

## Model Overview

Haidass-143M is a 143M-parameter bilingual language model trained on approximately 100B tokens of English and Chinese data. The entire training pipeline runs on the Huawei Ascend ecosystem, using the **MindSpeed-LLM** framework on Atlas A2 servers (910B). A custom 64,000-token bilingual vocabulary (SentencePiece BPE) was trained alongside the model. This model is competitive among multilingual models under 150M parameters and ranks favorably across multiple evaluation benchmarks.

## Key Features

- **Fully Ascend-native**: Trained entirely on Huawei Ascend 910B NPUs using the MindSpeed-LLM framework
- **Bilingual**: Trained on a mixture of English and Chinese data


## Intended Use

This is a research model, suitable for:
- Studying training dynamics of small models on Ascend NPUs
- English/Chinese language modeling research
- Serving as a base model for fine-tuning or annealing experiments

## Limitations

- Small model scale; reasoning and generation capabilities are limited
- raw pretrained model only
