Score in Context
What these scores mean
This is a reporting-family ranking: a weighted average of sourced hard-knowledge and agentic-research benchmarks. It rewards models that combine deep knowledge with the ability to search, browse, and synthesize.
Known limitations
Research quality also depends on the harness (search tools, retrieval, citations UI), which benchmarks only partly capture. Models need sourced coverage on at least a quarter of the family to appear.
About this ranking
Ranking data as of November 13, 2026
Research work stresses two things at once: deep, reliable knowledge (GPQA, Humanity's Last Exam, frontier-science evaluations) and the ability to actually go find and synthesize sources (BrowseComp, DeepSearch-QA, GAIA). This reporting family blends both, weighted toward the hard-knowledge and browsing benchmarks that separate research-grade models from good chat models.
This page ranks models using only sourced benchmarks in the research reporting family — hard knowledge plus agentic web research — rather than the full provisional leaderboard.
Atria Dawn Preview leads this ranking with a score of 93.9, followed by GPT-6 Astra (93.8) and GPT-5.6 Sol (93.4). The top three are separated by just a few points — any of them would perform well for this use case.
The best open-weight option is Atria Dawn Preview (ranked #1 with a score of 93.9). Open-weight models are highly competitive in this category — self-hosting is a viable alternative to proprietary APIs.

Questions
What is the best LLM for research?
The top rows of this table lead the sourced blend of hard-knowledge (GPQA, HLE) and agentic-research (BrowseComp, DeepSearch-QA) benchmarks — the two capabilities research work actually stresses. The ranking recomputes on every data refresh; check the answer box above for the current leader.
What is the best AI for deep research?
Deep-research products bundle a model with a browsing-and-synthesis harness, so pick from the BrowseComp and DeepSearch-QA leaders here, then compare the products built on them. A strong model in a weak harness will still miss sources; benchmark scores set the ceiling, the product sets how close you get.
Can I trust LLM citations in research?
Only after verification. Even the top HLE scorers fabricate citations at a nonzero rate, and browsing-enabled models can misread the sources they find. Use models from this table to draft and discover, and verify every load-bearing citation before it ships — the leaders lower the error rate, none eliminate it.
What is the best free LLM for research?
The strongest open-weight rows in this family can be self-hosted at no per-token cost — check which open models appear in the table, then see the open-source rankings and local LLM guide for hardware requirements. For occasional use, most frontier providers offer rate-limited free tiers of their chat products.
