AGENTS THAT ANSWER — AND RESEARCH
From instant, cited answers to deep, multi-step investigations with real deliverables.
Not every question needs the same depth
Sometimes your agent needs a fast, grounded answer. Sometimes it needs to investigate, synthesize, and produce a report you can actually use. Valyu Agents handle both — using the same search infrastructure, the same source control, and the same commitment to traceability.
Try ValyuAnalyze the legal framework governing commercial space activities. Examine the Outer Space Treaty and subsequent agreements, catalog national space laws (US Commercial Space Launch Act, Luxembourg space mining law, UAE space law), document liability frameworks for space debris and collisions, analyze property rights for space resources (asteroid mining, lunar resources), evaluate licensing requirements for launches

Output
Federal Reserve Interest Rate Changes and Their Impact on Regional US Housing Markets (2024-2026)
Executive Summary
The Federal Reserve’s aggressive interest rate adjustments from 2022-2025 have produced sharply divergent impacts across US regional housing markets, creating a “tale of two markets” driven primarily by supply constraints rather than uniform monetary policy transmission. The Fed raised rates 4.25 percentage points from early 2022 through mid-2023 (reaching 5.33%), then cut rates 225 basis points through December 2025, yet mortgage rates declined only 80-90 basis points.
Regional outcomes diverged dramatically by December 2025:
• Northeast and Midwest (supply-constrained): Median prices $331K—540K with continued price

Meta-analyses of immunotherapy efficacy in lung cancer

Recent meta‑analyses consistently show that immune‑checkpoint inhibition improves survival across the lung‑cancer spectrum. In the adjuvant setting for early‑stage non‑small‑cell lung cancer (NSCLC), a network meta‑analysis of 19 randomized trials reported that immune‑checkpoint inhibitor (ICI) therapy lengthened disease‑free survival (DFS) to a median of 53.47 months versus 39.49 months with chemotherapy or placebo (Nature).
In advanced disease, pooled data from randomized trials demonstrate a robust overall‑survival (OS) advantage for immunotherapy over chemotherapy. Real‑world French data showed median OS of 16.4 months with first‑line ICIs versus 11.6 months with chemotherapy (Nature). Trial‑level meta‑analyses of PD‑1/PD‑L1 plus CTLA‑4 combinations reported a 69 % reduction in the risk of progression (HR 0.69, 95 % CI 0.56–0.85) (Medrxiv). Dual‑immunotherapy plus chemotherapy further increased median OS to ≈15.8 months (Cureus).
Biomarker‑focused meta‑analyses indicate that high tumor‑mutational burden (TMB) predicts greater immunotherapy benefit (Nih). Together, these systematic reviews confirm that immunotherapy provides significant survival benefits.
When to Use Answer Mode

SoTA across several benchmarks

FreshQA is updated roughly every week, contains 600 time-sensitive questions that assess how effectively APIs handle recent and evolving information. The benchmark is critical for use cases such as news summarization, event tracking, and trend monitoring. Our evaluation used the Aug 27th test set, the most recent release available at the time of testing.
