OpenAI released solutions to three long-standing math problems, including a claimed refutation of the Exponential Time Hypothesis, a core assumption about computational difficulty. Anthropic released its own ETH refutation hours later, after its mathematician Levent Alpöge said OpenAI's work built on existing research. MIT's Ryan Williams is organizing a community response and an open letter.
Google DeepMind released Genie 4 in research preview, a world model it says generates photorealistic interactive scenes with matching real-time audio and accepts typed prompts mid-simulation. It holds a consistent scene for up to two minutes. Trusted testers get access now; Google AI Ultra subscribers follow in Project Genie.
Rohit Patel leaves Meta after eight years to launch Ndoc, an AI-native workspace pitched as a replacement for Microsoft Office and Google Workspace. Patel says Ndoc opens an alpha to wait-listed customers, free to sign up with charges for usage and tokens. He plans to open-source its .ndoc.html file format.
Opera introduces WebAI, an early preview in Opera One that runs AI models locally in the browser. It supports open-weight models including Google's Gemma, and Apple's on-device model on Macs. Opera says processing stays on the device, and users must opt in.
Wiz Research discloses PHP2Shell, memory-safety bugs in core PHP that allow unauthenticated remote code execution and are rated up to CVSS 9.2. PHP shipped fixes on October 21, but AWS says attackers exploited the flaws before disclosure. The bugs affect PHP 5.4 and later, so patching PHP 8.x runtimes is urgent.
Hamel Husain and Antaripa Saha tested six decision models on 98 apartment-leasing traces and found default 0.50 thresholds undercut performance. After tuning, OpenAI Decisions (GPT-6 Luna) reached F1 0.87 at 3.72 cents per 100 runs; Perplexity Decider scored 0.79 at 0.82 cents. They urge teams to set precision and recall minimums, tune thresholds, and check calibration.
PaperPilot adds a PaperPilot SLM quantized to Q4_K_M GGUF at 380 MB, per its Oct. 27 commit, alongside a v0.6 release. The Rust PDF toolkit runs locally and connects to coding agents such as Claude Code through an MCP server. The community edition is Apache 2.0; an Enterprise edition is separate.
Th0rgal's Orb repository bundles AI providers, machines and agent harnesses into one client, with a desktop app built in Tauri and SolidJS and an iOS app in SwiftUI. The project, formerly sandboxed.sh, keeps that name for its Rust backend. The repository lists 639 stars and 62 forks.
Pomerado, a YC F26 company, released its core integration-minting harness under the MIT license, letting agents turn websites into MCP servers from a plain-language task description. Minting requires Node 24 and an OpenAI API key, while running a finished integration makes no model request. The company says integrations work on sites behind logins and two-factor authentication.
Anthropic filed for an initial public offering on Monday and plans to list under the ticker ANT, with revenue of $16.3 billion in the first half of 2026 against an operating loss of $693 million. The seven co-founders will control 50.1% of shareholder voting power through a Founder LLC, a structure Anthropic says preserves its AI safety mission. The filing did not disclose the raise amount or share price.
