Researchers introduce SlimSearcher, a framework that trains AI web agents to perform complex information-seeking tasks with 17-58% fewer tool calls while maintaining or improving accuracy. The approach combines efficient trajectory filtering during supervised fine-tuning with adaptive reward gating during reinforcement learning to eliminate wasteful search behaviors.
Researchers present a decision-making framework to optimize when large language models should call external tools like web search. The study reveals that models often misjudge their actual need for tool use, and proposes lightweight estimators trained on hidden states to improve tool-calling decisions, demonstrating performance gains across multiple tasks.
Researchers introduce CREST-Search, a red-teaming framework that exposes vulnerabilities in web-augmented LLMs by crafting benign-seeming queries designed to trigger unsafe citations from the internet. The study reveals that integrating web search into language models creates new safety risks beyond traditional LLM harms, requiring specialized defensive strategies.
OpenAI has launched ChatGPT search, a new feature that provides fast, timely answers with links to relevant web sources. This enhancement integrates real-time web search capabilities directly into ChatGPT, allowing users to get current information alongside AI-generated responses.
Seltz, a web search startup founded by veterans from Amazon and Pinecone, raised $12.5 million in seed funding led by Speedinvest and Capital B. The company is building search infrastructure specifically designed for AI agents rather than human users, addressing a gap in how autonomous systems access and process web information.
Researchers conducted a systematic analysis of text ranking methods in deep research tasks, examining how LLM-based agents retrieve and process web information. The study reveals that agent-generated queries follow web-search syntax favoring lexical and sparse retrievers, passage-level units outperform documents under context constraints, and a new query-translation method significantly improves retrieval effectiveness.
TreeSeeker is a new inference-time framework that improves deep web search by using tree-structured trial-and-error navigation. The system balances exploration and exploitation through textual UCB signals, demonstrating consistent improvements over baseline models on multiple benchmarks.
Researchers introduce VeriTrip, a new benchmark for evaluating travel planning AI agents on their ability to reason over unstructured web data rather than structured APIs. The benchmark addresses critical gaps in agent evaluation by testing performance against information noise, contradictory facts, and multimodal content, revealing a significant trade-off between autonomous information retrieval and instruction following.
TimeSeek introduces a benchmark showing that AI language models perform best at predicting binary market outcomes early in a market's lifecycle and on high-uncertainty markets, but struggle near resolution and on consensus markets. Web search generally improves forecasting accuracy across models, though not uniformly, while simple ensembles reduce errors without beating market performance overall.
