Research independently. Synthesize coherently. English | 简体中文 **Overview** This repository open-sources the LongCat-DeepResearch harness for open-ended research. It captures evolving research requirements in an executable ResearchSpec, supports independent section research and writing, and makes targeted revisions to the assembled report instead of repeatedly rewriting it. Users can run deep-research tasks with their own services by implementing `llm`, `web_search`, and `web_fetch` according to the backend contract. Paired with our LongCat-2.0-based model enhanced for deep research, the complete system outperforms the Deep Research offerings from ChatGPT, Claude, and Gemini on DeepResearchBench, DeepResearchBench II, and ResearchRubrics. ![LongCat-DeepResearch benchmark overview](assets/benchmark_overview.png) **Research Harness** ![LongCat-DeepResearch harness](assets/harness_overview.png) The harness follows..."},"evidence_pages":[],"related_signals":[{"id":"967e247e-400a-4b20-82e3-528a251226ce","url":"https://onlylabs.fyi/signals/967e247e-400a-4b20-82e3-528a251226ce","source_url":"https://github.com/meituan-longcat/LongCat-2.0","title":"meituan-longcat/LongCat-2.0","context":null,"kind":{"key":"repo_new","label":"Repo"},"org":{"slug":"meituan","name":"Meituan (LongCat)","category":"neolab"},"occurred_at":"2026-06-29T12:46:02+00:00","first_seen_at":"2026-06-30T07:00:38.636223+00:00","date_source":"source"},{"id":"0a91d1ce-8fe2-4278-a0a7-da45686c7124","url":"https://onlylabs.fyi/signals/0a91d1ce-8fe2-4278-a0a7-da45686c7124","source_url":"https://github.com/meituan-longcat/omni-flow-sglang","title":"meituan-longcat/omni-flow-sglang","context":"Python","kind":{"key":"repo_new","label":"Repo"},"org":{"slug":"meituan","name":"Meituan (LongCat)","category":"neolab"},"occurred_at":"2026-06-25T08:10:08+00:00","first_seen_at":"2026-07-02T07:01:29.309315+00:00","date_source":"source"},{"id":"07297575-7bb4-4049-87e3-ca687c229900","url":"https://onlylabs.fyi/signals/07297575-7bb4-4049-87e3-ca687c229900","source_url":"https://github.com/meituan-longcat/omni-flow","title":"meituan-longcat/omni-flow","context":"Python","kind":{"key":"repo_new","label":"Repo"},"org":{"slug":"meituan","name":"Meituan (LongCat)","category":"neolab"},"occurred_at":"2026-06-25T08:05:18+00:00","first_seen_at":"2026-07-02T07:01:29.309315+00:00","date_source":"source"},{"id":"b73c1c25-7430-4e70-a27b-e4e8ddccb714","url":"https://onlylabs.fyi/signals/b73c1c25-7430-4e70-a27b-e4e8ddccb714","source_url":"https://github.com/meituan-longcat/MineExplorer","title":"meituan-longcat/MineExplorer","context":"Python","kind":{"key":"repo_new","label":"Repo"},"org":{"slug":"meituan","name":"Meituan (LongCat)","category":"neolab"},"occurred_at":"2026-05-29T05:07:05+00:00","first_seen_at":"2026-06-13T07:00:24.333651+00:00","date_source":"source"},{"id":"94c3b1d1-3a74-4f03-a1e9-f29d4c43f3f4","url":"https://onlylabs.fyi/signals/94c3b1d1-3a74-4f03-a1e9-f29d4c43f3f4","source_url":"https://github.com/meituan-longcat/VitaBench-2.0","title":"meituan-longcat/VitaBench-2.0","context":"Python","kind":{"key":"repo_new","label":"Repo"},"org":{"slug":"meituan","name":"Meituan (LongCat)","category":"neolab"},"occurred_at":"2026-05-26T08:19:36+00:00","first_seen_at":"2026-06-05T20:58:48.478227+00:00","date_source":"source"},{"id":"fd1392be-b52c-47b6-a2d3-e1322ca8a782","url":"https://onlylabs.fyi/signals/fd1392be-b52c-47b6-a2d3-e1322ca8a782","source_url":"https://github.com/meituan-longcat/WBench","title":"meituan-longcat/WBench","context":"Python","kind":{"key":"repo_new","label":"Repo"},"org":{"slug":"meituan","name":"Meituan (LongCat)","category":"neolab"},"occurred_at":"2026-05-22T10:46:52+00:00","first_seen_at":"2026-06-05T20:58:48.478227+00:00","date_source":"source"}]}
