BrowseComp (Browsing Competition) is a benchmark designed to evaluate AI agents' ability to browse the internet and retrieve hard-to-find, deeply entangled information. The benchmark comprises 1,266 challenging questions that require agents to persistently navigate multiple websites, reason about factuality, and creatively search to find answers that would be difficult for humans to locate within 10 minutes.

The benchmark was created by human trainers who designed questions to be extremely challenging - not solvable by existing models like GPT-4o (with or without browsing) or early versions of OpenAI Deep Research. Questions cover diverse topics including TV shows & movies (16.2%), science & technology (13.7%), art (10.0%), history (9.9%), sports (9.7%), music (9.2%), video games (5.6%), geography (5.5%), and politics (4.7%).

The benchmark follows an "inverted" design approach where trainers start with a fact and create questions where the answer is easy to verify but hard to find. For example: identifying a scientific paper from EMNLP 2018-2023 where the first author did undergrad at Dartmouth and fourth author at UPenn.

Human performance on BrowseComp shows its difficulty: trainers solved only 29.2% of problems within 2 hours, with 70.8% giving up after the time limit. This demonstrates that BrowseComp measures core browsing capabilities including persistence, creative search strategies, and factual reasoning - making it an important benchmark for evaluating web-browsing AI agents.

The FACTS Grounding benchmark measures language models' ability to generate text that is factually accurate with respect to given context in the user prompt. Each prompt includes a user request and a full document with a maximum length of 32k tokens, requiring long-form responses that are fully grounded in the provided context document while fulfilling the user request.

The evaluation process uses automated judge models in two phases: (1) responses are disqualified if they do not fulfill the user request; (2) they are judged as accurate if the response is fully grounded in the provided document. The automated judge models were comprehensively evaluated against a held-out test-set, and the final factuality score is an aggregate of multiple judge models (Gemini 1.5 Pro, GPT-4o, and Claude 3.5 Sonnet) to mitigate evaluation bias.

The benchmark contains 860 public examples ('Open' split) and 859 private examples ('Blind' split) of natural, complex LLM prompts written by humans. The prompts span various enterprise domains including finance, technology, retail, medical, and legal, with tasks including fact finding, summarization, effect analysis, and concept comparison. Context documents have a mean length of 2.5k tokens with a maximum of 32k tokens.

Key features:
• Long-form grounded response generation up to 32k token context
• Multi-judge evaluation system to reduce bias
• Eligibility filter to prevent metric gaming
• Diverse enterprise domains and task types
