VQAv2 Leaderboard

Open-ended visual question answering over COCO images. Current leaders, methodology, and citation sources for VQAv2.

Overview

Open-ended visual question answering over COCO images.

How it is measured: VQA accuracy with 10-annotator agreement.

What this benchmark measures

  • open-ended visual question answering
  • image grounding

Relevant to:

  • vision-language model screening
  • image question answering

Failure modes it exercises:

  • answering image questions from language priors rather than the image

Method and its limits

Open-ended questions over COCO photographs, each with ten independently collected ground-truth answers, scored by an automatic accuracy metric over that answer set.

  • Answers are short and open-ended, so the metric rewards matching common phrasing rather than understanding.
  • The official source documents the dataset release but does not publish the test-dev split definition or the accuracy formula, so the exact protocol behind any reported figure is not established from it.

204,721 COCO images, 1,105,904 questions and 11,059,040 ground-truth answers in the April 2017 v2.0 full release, as registered on the official site. Earlier v1.0 and v1.9 releases are separate and not interchangeable.

How to read this score

Accuracy is interpretable only against a stated split and answer-normalisation rule. Because frontier multimodal models now score far above the 2017 baselines, the benchmark functions as a floor check.

Similarity to real tasks: Medium — Established from the official dataset source: VQA v2.0 pairs 204,721 COCO images with 1,105,904 open-ended questions, each carrying ten ground-truth answers, and the v2 release is explicitly balanced so that language priors alone are insufficient. Open-ended questions about photographs resemble real image-understanding requests. Answers are short, so it does not test description, reasoning over documents, or multi-image comparison.

Data contamination risk: High — VQAv2 has been public since 2017 and is standard pretraining and evaluation data for vision-language models. No run-specific overlap audit is registered.

Benchmark gaming risk: Medium — The v2 balancing was introduced specifically to defeat language-prior shortcuts, which mitigates the original failure mode, but answer-normalisation rules still affect reported accuracy.

What you still need to test yourself

  • Test on your own imagery and question types; COCO photographs are not documents or screenshots.
  • Establish the split and answer-normalisation rule before comparing any published figures.

This benchmark supports decisions about:

  • Use as a floor check that a multimodal model grounds answers in the image.

Limitations

  • Short-answer format; not evidence of description or multimodal reasoning quality.
  • Effectively a floor check for current models.

Official dataset source reviewed 2026-10-12. VQAv2 is treated as an aging 2017 benchmark.

What this evidence does not cover

  • Only one model is currently scored on this page, so no comparison is supported.
  • The split behind the registered score is not stated by its source, so it cannot be placed against a VQAv2 figure whose split is stated.
