In earlier work, each use case usually got its own dataset, training objective and architecture, and sentence-embedding research developed separately from neural retrieval. This OpenAI paper shows that one simple recipe can produce… 2. **[HealthBench: Evaluating Large Language Models Towards Improved Human Health](https://md.research.elamur.ai/free/en/papers/arora-2025-healthbench-evaluating-large-language-models/)** *(2025 · 115 citations)* Most medical benchmarks for LLMs use multiple-choice or short-answer questions. These capture little of how people actually seek health help, are rarely checked against expert judgment, and are often close to saturated. HealthBench, from OpenAI, addresses this with 5,000 realistic single- and multi-turn health… ## Also in our library 4 more works of theirs are in our library without a page here yet; they will appear as we publish them. ## Co-authors here 12 of 15 co-authors with a page, the most papers together first. - [Alec Radford](https://md.research.elamur.ai/free/en/authors/alec-radford/) - [Alex Beutel](https://md.research.elamur.ai/free/en/authors/alex-beutel/) - [Arvind Neelakantan](https://md.research.elamur.ai/free/en/authors/arvind-neelakantan/) - [Chris Hallacy](https://md.research.elamur.ai/free/en/authors/chris-hallacy/) - [Jason Wei](https://md.research.elamur.ai/free/en/authors/jason-wei/) - [Jerry Tworek](https://md.research.elamur.ai/free/en/authors/jerry-tworek/) - [Jesse Michael Han](https://md.research.elamur.ai/free/en/authors/jesse-michael-han/) - [Jong Wook Kim](https://md.research.elamur.ai/free/en/authors/jong-wook-kim/) - [Karan Singhal](https://md.research.elamur.ai/free/en/authors/karan-singhal/) - [Nikolas Tezak](https://md.research.elamur.ai/free/en/authors/nikolas-tezak/) - [Pranav Shyam](https://md.research.elamur.ai/free/en/authors/pranav-shyam/) - [Qiming Yuan](https://md.research.elamur.ai/free/en/authors/qiming-yuan/) ## Cited by Papers of our library cite their works 4,332 times (of the 140,884 papers whose bibliographies we read); [163 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/johannes-heidecke/cited-by/).
