GPT-4V(ision) system card update — clarify input modalities and constraints

AI Impact Summary

The release of a GPT-4V(ision) system card formalizes vision capabilities and how they are surfaced in the OpenAI API. It documents supported input modalities, expected response formats, and usage constraints, enabling engineers to design prompts and handle errors with the documented behavior. This reduces integration risk and helps governance and compliance teams enforce content and latency expectations for image-based tasks.
