MMNeedle is a stress test for long-context multimodal reasoning. Each example
contains a sequence of haystack images created by stitching MS COCO sub-images
into 1×1, 2×2, 4×4, or 8×8 grids. Given textual needle descriptions (derived
from MS COCO captions), models must predict which haystack image and which
sub-image cell matches the caption—or report that the needle is absent.
This dataset card accompanies the official Hugging Face release so researchers no
longer need to… See the full description on the dataset page:
