Special Notes

We have released 7 Baichuan models of lyra version including Baichuan-7B, Baichuan-13B-Base, Baichuan-13B-Chat, Baichuan2-7B-Base, Baichuan2-7B-Chat, Baichuan2-13B-Base and Baichuan2-13B-Chat.

These highly optimized Baichuan models are suitable for Ampere (A100/A10) as well as Volta (V100).

Model Card for lyraBaichuan

lyraBaichuan is currently the fastest Baichuan models (Baichuan-7B, Baichuan-13B, Baichuan2-7B, Baichuan2-13B) available. The inference speed of lyraBaichuan has achieved up to 4300+ tokens/s on A100, up to 2.4x acceleration upon the torch version.

Among its main features are:

  • device: Nvidia GPU with Amperer architecture or Volta architecture (A100 or higher, V100).
  • batch_size: compiled with dynamic batch size, maximum depends on device. 
  • MEMOPT mode: significantly optimized VRAM usage and increased speed

We use the Baichuan2-7B-Base and Baichuan2-13B-Base model for measurement, but this optimized inference is also applicable to other Baichuan models, including Baichuan-7B and Baichuan-13B.

Speed

  • Evaluated at tokens/s (#tokens of input and output divided by inference time cost)
  • test on A100 40G
  • MEMOPT mode
