The tasks implement project features in sequence, simulating real-world human development workflows.   \r\n\r\n2. When designing Web-Bench, we aim to cover the foundational elements of Web development: Web Standards and Web Frameworks. Given the scale and complexity of these projects, which were designed by engineers with 5-10 years of experience, each presents a significant challenge. On average, a single project takes 4–8 hours for a senior engineer to complete.   \r\n\r\n3. On our given benchmark agent (Web-Agent), SOTA (Claude 3.7 Sonnet) achieves only 25.1% Pass@1, significantly lower than SWE-Bench's Verified (65.4%) and Full (33.8%) scores (2025.4).","description_withheld":null,"homepage":"https://huggingface.co/datasets/bytedance-research/Web-Bench","introduced_date":"2025-05-12","introduced_date_note":null,"introduced_by":{"paper":"/paper/web-bench-a-llm-code-benchmark-based-on-web","title":"Web-Bench: A LLM Code Benchmark Based on Web Standards and Frameworks","first_author":"Kai Xu","url":null},"license":{"name":"CC BY","url":"https://creativecommons.org/licenses/by/4.0/"},"modalities":[],"tasks":[{"name":"task","url":null,"datasets_with_task":"/datasets/task/task"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["Web-Bench"],"data_loaders":[],"num_papers_in_archive":2,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/on-web-bench","task":"","dataset_variant":"Web-Bench","rows":40,"metrics":["Pass@1","Pass@2"],"first_row_in_archive_order":{"model":"claude-3-7-sonnet-20250219-thinking","paper":"/paper/web-bench-a-llm-code-benchmark-based-on-web","metrics":{"Pass@1":"25.11%","Pass@2":"35.33%"},"code_links":[{"title":"bytedance/Web-Bench","url":"https://github.com/bytedance/Web-Bench"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/web-bench-a-llm-code-benchmark-based-on-web","title":"Web-Bench: A LLM Code Benchmark Based on Web Standards and Frameworks","date":"2025-05-12","rows_on_this_dataset":40,"code_links":1,"syntology":null}],"syntology_totals":{"read_at":"2026-09-25T09:33:49+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
