# CLIP-IN: Enhancing Fine-Grained Visual Understanding in CLIP via Instruction Editing Data and Long Captions
<!-- Provide a quick summary of what the model is/does. -->
### Model Description
Despite the success of Vision-Language Models (VLMs) like CLIP in aligning vision and language, their proficiency in detailed, fine-grained visual comprehension remains a key challenge. We present CLIP-IN, a novel framework that bolsters CLIP’s fine-grained perception through two core innovations. Firstly, we lever-
age instruction-editing datasets, originally designed for image manipulation, as a
unique source of hard negative image-text pairs. Coupled with a symmetric hard
negative contrastive loss, this enables the model to effectively distinguish subtle
visual-semantic differences. Secondly, CLIP-IN incorporates long descriptive cap-
tions, utilizing rotary positional encodings to capture rich semantic context often
missed by standard CLIP. Our experiments demonstrate that CLIP-IN achieves sub-
stantial gains on the MMVP benchmark and various fine-grained visual recognition
tasks, without compromising robust zero-shot performance on broader classifica-
tion and retrieval tasks. Critically, integrating CLIP-IN’s visual representations into
Multimodal Large Language Models significantly reduces visual hallucinations
and enhances reasoning abilities. This work underscores the considerable potential
of synergizing targeted, instruction-based contrastive learning with comprehensive
descriptive information to elevate the fine-grained understanding of VLMs
