GLM is a General Language Model pretrained with an autoregressive blank-filling objective and can be finetuned on various natural language understanding and generation tasks.

Please refer to our paper for a detailed description of GLM:

Model description

glm-2b is pretrained on the Pile dataset. It has 36 transformer layers, with hidden size 4096 and 64 attention heads in each layer. The model is pretrained with autoregressive blank filling objectives designed for natural language understanding, seq2seq, and language modeling. Find more details from our repo .

How to use

Please refer the instruction in our Github repo.

We use three different mask tokens for different tasks: [MASK] for short blank filling, [sMASK] for sentence filling, and [gMASK] for left to right generation. You can find examples about different masks from here . The prediction always begin with a special <|startofpiece|> token and ends with a <|endofpiece|> token.
