SQuAD v2

Llama 3.1-405B 81.8% leads since November 2024
Dropped

Models extract answers from Wikipedia paragraphs and must abstain on over 50,000 adversarial unanswerable questions. Scored by exact match and F1.

Saturated. The test set is hidden, so cards report the dev set.

In the authors’ words

Extractive reading comprehension systems can often locate the correct answer to a question in a context document, but they also tend to make unreliable guesses on questions for which the correct answer is not stated in the context. Existing datasets either focus exclusively on answerable questions, or use automatically generated unanswerable questions that are easy to identify. To address these weaknesses, we present SQuAD 2.0, the latest version of the Stanford Question Answering Dataset (SQuAD). SQuAD 2.0 combines existing SQuAD data with over 50,000 unanswerable questions written adversarially by crowdworkers to look similar to answerable ones. To do well on SQuAD 2.0, systems must not only answer questions when possible, but also determine when no answer is supported by the paragraph and abstain from answering. SQuAD 2.0 is a challenging natural language understanding task for existing models: a strong neural system that gets 86% F1 on SQuAD 1.1 achieves only 66% F1 on SQuAD 2.0.

2 models share the top score of 81.8% among models released by July 2024

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in July 2024, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 Llama 3.1-405B 81.8%
  2. 2 Llama 3.1-70B 81.8%
  3. 3 Llama 2-70B 80.7%
  4. 4 PaLM 2-L 80.5%
  5. 5 Llama 2-34B 77.4%
  6. 6 Llama 3.1-8B 77%
  7. 7 Llama 2-13B 72.9%
  8. 8 Llama 2-7B 67.2%
