Haidass-143M

English | 中文

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
