Recent years have witnessed a significant increase in the performance of
Vision and Language tasks. Foundational Vision-Language Models (VLMs), such as
CLIP, have been leveraged in multiple settings and demonstrated remarkable
performance across several tasks. Such models excel at object-centric
recognition yet learn text representations that seem invariant to word order,
failing to compose known concepts in novel ways. However, no evidence exists
that any VLM, including large-scale single-stream models such as GPT-4V,
identifies compositions successfully. In this paper, we introduce a framework
to significantly improve the ability of existing models to encode compositional
language, with over 10% absolute improvement on compositionality benchmarks,
while maintaining or improving the performance on standard object-recognition
and retrieval benchmarks. Our code and pre-trained models are publicly
