Leonardo AI Scales Image Captioning with NVIDIA GH200 on Lambda
excerpt
content
Lambda provides cloud support for accelerating deep learning workflows vital to cutting edge generative technology. Leonardo AI is a startup creating and serving advanced text-to-image services & uses Lambda’s compute resources for their production systems and research programs for their flexibility and reliability. TL;DR We captioned thirty million images from our internal dataset using CogVLM-17B on the NVIDIA GH200 architecture. The GH200 alleviates a communication bottleneck commonly seen in VRAM-limited A100-40GN nodes and allows us to reach a batch size that saturates GPU utilisation. Porting our existing captioning pipeline to the GH200 cluster configured by Lambda took only a day & improved throughput by over a factor of 3x. Throughput gains allow finer-grained synthetic captions, used to train more performant text-to-image models, ultimately creating better results at inference stage. The Benchmarked Task Our pipeline entails loading a batch of ...
