EVA-CLIP-18B: Scaling CLIP to 18 Billion Parameters

Sun, Quan, Wang, Jinsheng, Yu, Qiying et al.

Understand

Scaling up contrastive language-image pretraining (CLIP) is critical for empowering both vision and multimodal models.

  • We present EVA-CLIP-18B, the largest and most powerful open-source CLIP model to date, with 18-billion parameters.
  • With only 6-billion training samples seen, EVA-CLIP-18B achieves an exceptional 80.7% zero-shot top-1 accuracy averaged across 27 widely recognized image classification benchmarks, outperforming its forerunner EVA-CLIP (5-billion parameters) and other open-source CLIP models by a large margin.
  • Remarkably, we observe a consistent performance improvement with the model size scaling of EVA-CLIP, despite maintaining a constant training dataset of 2-billion image-text pairs from LAION-2B and COYO-700M.
