Keenable launched version 1.0 of its AI web search API, claiming first place on the Artificial Analysis Search Index (BrowseComp, DeepSearchQA and AA-Omniscience) and on NEEDLE, its open-source benchmark rerun daily on fresh queries. The release adds 100 million knowledge cards, which summarize key facts on a topic and are refreshed frequently via partner APIs, plus dynamic snippets that read full documents and extract only the needed context, cutting token consumption by 50% on research tasks. Since its launch two months ago the service has served millions of agent queries, and new accounts start with 100,000 requests through one key and one MCP endpoint.

Google releases Gemini 4 Hydrogen to power more complex Search answers

Google released Gemini 4 Hydrogen, a fast-execution model it calls its biggest Search improvement yet, and is rolling the update out to all Search users globally. Google says Hydrogen completes tasks 2.5 times faster than Gemini 3.8 Flash and beats the more powerful Gemini 4 Argon on the Artificial Analysis Intelligence Index at its default high thinking level. In Search it improves intent understanding, typo handling, fan-out subqueries and visual responses in AI Mode, and it is also coming to AI Studio, the Gemini API, the Gemini App and Antigravity.

Google Search upgrades globally to Gemini 4 Hydrogen

Google Search has moved all users worldwide to Gemini 4 Hydrogen, which the company calls its biggest model upgrade to Search yet. The model improves intent understanding for multi-part and typo-heavy questions, adds deeper instruction following and tool calling, and strengthens query fan-out to surface links users might not otherwise find. Responses also become more visual, with more images, comparison tables and custom tools, across all supported AI Mode languages.

Study finds ChatGPT, Gemini and Perplexity recommend fake retail websites

A study by IP protection firm Podqi found that ChatGPT, Gemini and Perplexity all cited or displayed risky retail websites, defined as fake storefronts, reregistered old brand domains or dead sites, in answers to shopping questions about 151 brands. Across 6,795 answers collected in two September testing periods, Perplexity surfaced risky sites in 15 percent of responses, ChatGPT in 8 percent and Gemini in 4 percent, while ChatGPT warned about the risky site it surfaced 24 percent of the time. Queries about smaller brands produced risky sites about twice as often as those about larger companies, and prompts about regional brand websites triggered them more frequently, with Perplexity once naming the wrong page as Stüssy's official site.

Building a Daily Dependency Watcher with LangGraph and Amazon Bedrock AgentCore Web Search

The Web Search API in Amazon Bedrock AgentCore is now available, giving agents current web results through a single SigV4-signed API call served from a web index Amazon operates. A walkthrough builds a daily dependency watch as a LangGraph graph that researches npm, PyPI, and container base images in parallel, with date windows, blocklists, and search budgets enforced in code. In testing, the three branches finished in 36 seconds versus 99 seconds run sequentially.

Amazon Bedrock AgentCore Web Search API Released

Amazon Bedrock AgentCore now offers a standalone Web Search API, letting developers call InvokeWebSearch directly from AWS SDKs or the AWS CLI with a single request and no resources to create. It returns ranked results from an Amazon-operated web index, each with a text extract and, when available, title, URL, and publication time, with domain and date filters. Requests are signed with SigV4 and IAM, using the same permission as the AgentCore Gateway route.

Apple's Learned Support Functions Speed Up RAG Retrieval

Apple researchers presented "Amortizing Maximum Inner Product Search with Learned Support Functions" at ICML 2026, training small neural networks offline to route queries toward their best-matching keys faster. SupportNet learns the support function via input convex neural networks (ICNNs) to improve cluster routing, while KeyNet directly outputs the best-matching key vector, kept geometrically grounded by a consistency loss from Euler's theorem. Both are trained on the actual query distribution, trading an upfront amortization cost for faster, more accurate retrieval at inference time.

OpenAI Says ChatGPT Search Volume Is About 20% of Google's as Weekly Users Reach 1.2 Billion

OpenAI says ChatGPT's search-like query volume is now roughly one-fifth of Google's, and the app grew from 1 billion to 1.2 billion weekly active users in about two months. ChatGPT consumer product lead Adam Fry shared the figures at an OpenAI dinner in New York City, adding that users generate 1.5 billion images per week and that voice mode, combining dictation and speaking with ChatGPT, has 250 million combined weekly active users. Fry also said OpenAI plans to merge ChatGPT's Chat and Work modes, removing the toggle at the top of the app.

PFN releases PLaMo 3.1 Prime with Web search and Deep Research

Preferred Networks began offering PLaMo 3.1 Prime on October 27, 2026, adding Web search and a Deep Research feature that autonomously plans, collects, analyzes and writes source-cited reports over several minutes to tens of minutes. Deep Research also runs on-premises and can connect to internal document search systems, while the company reports an average ~15% score improvement across eight hallucination-related benchmarks including AA Omniscience versus PLaMo 3.0 Prime. PFN also cites 1.7x faster processing via speculative decoding and a 90% reduction in output tokens in non-reasoning mode, and launched a free PLaMo API plan plus a PLaMo Chat campaign offering Deep Research twice daily until November 30, 2026.
