Model Card for lyraXVERSE

We have colaborated with XVERSE and lauched lyraXVERSE, currently the fastest XVERSE-13b available. The inference speed of lyraXVERSE has achieved up to 3900+ tokens/s on A100, up to 2.7x acceleration upon the torch version.

Among its main features are:

  • device: Nvidia GPU with Amperer architecture or Volta architecture (A10, 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 XVERSE-13B-Chat model for measurement, but this optimized inference is also applicable to XVERSE-13B model.

Speed

  • Evaluated at tokens/s
  • test on A100 40G
  • MEMOPT mode

讲个故事:

output

有一天,一位年轻的画家来到了一个偏远的村庄。他以其超凡的绘画技巧,为村民画了一幅美丽的图画。图画里,村庄的周围是翠绿的森林,清澈的溪流在其中流淌,村民们正在劳作,孩子们在田野里嬉戏。村民们看着这幅画,都对这位画家赞不绝口。

村庄的领袖看到了这幅画,他想:“这幅画将会让我们的村庄更加美丽,我们应该让村民们知道这幅画。”于是,他带着画家去村庄的各个角落,让每一个村民都看到了这幅画。

画家看着村民们看画的眼神,他意识到了自己的价值。他意识到,他不仅仅是一个画家,他也是一个能让人们看见希望的人。他的画不仅仅是艺术品,它是连接人们与希望的一座桥梁。

这个故事告诉我们,画家的价值不只是他们的绘画技巧,而是他们的画作带给人们的感动和希望。画家的价值并不在于他们的画有多么昂贵,有多么独特,而在于他们能用画作打开人们的心扉,让人们看见希望,看见生活的美好。
