+This model is based on [bigscience/bloom-3b](https://huggingface.co/bigscience/bloom-3b). 
+
+We pruned its vocabulary from 250880 to 46145 with Chinese corpus to reduce GPU memory usage. So the total parameter is 2b5 now.
+
+# How to use
+```python
+from transformers import BloomTokenizerFast, BloomForCausalLM
+
+tokenizer = BloomTokenizerFast.from_pretrained('Langboat/bloom-2b5-zh')
+model = BloomForCausalLM.from_pretrained('Langboat/bloom-2b5-zh')
+
+print(tokenizer.batch_decode(model.generate(tokenizer.encode('中国的首都是', return_tensors='pt'))))
+```
