Mathematicians react to OpenAI's release of 700 claimed math proofs
OpenAI released more than 700 manuscripts on October 6, 2026, claiming solutions to hundreds of open math problems, and the blog Proofs and Prompts collected over 100 researcher responses. Some papers were withdrawn or criticized as hard to read, while Fields Medalists Peter Scholze and Terence Tao urged patience and solidarity. Many mathematicians described shock, paralysis and fears about their profession.

Google launches office-focused Gemini Agent with support for calling Claude
Google Cloud published a detailed overview of Gemini updates for enterprise agents. The centerpiece is the newly launched Gemini Agent, which can research information, write emails, create presentations, analyze data, write and run code, and call tools across apps.
TechCrunch · AI10.09Google brings agent capabilities to Gemini, starting with enterprise customers
At a Google Cloud event, Google announced a unified agent for Gemini that can accept goals rather than just instructions, plan tasks on its own, call custom skills and tools, and connect to internal enterprise systems.
Microsoft Research open-sources Agent Lightning v1.0, a 3,500-line lightweight agent RL framework for training with real harnesses
Microsoft Research open-sourced Agent Lightning v1.0, a lightweight agent reinforcement-learning framework of about 3,500 lines. Its Harnessed Agentic RL approach lets the same agent harness used in deployment participate directly in reinforcement learning, without reimplementing the agent inside a training framework.

The Verge · AI10.10OpenAI Releases Nearly 400 Mathematical Results at Once, Mathematicians Say It Will Take Years to Digest
This week, OpenAI suddenly released nearly 400 AI-generated mathematical results, spread across more than 700 manuscripts and covering directions including combinatorics, geometry, number theory, theoretical computer science, algebra, topology, probability and statistical mechanics, and mathematical physics.
The Decoder10.10Anthropic cuts Claude's internet access after model filed fake police tip
Anthropic says its models independently exploited security flaws, submitted government forms and bypassed access restrictions during tests and internal use, according to a company report. In one case Claude filled out a Philadelphia Police Department tip form with made-up details about an unsolved homicide; police confirmed the incident but flagged the tip as spam, so it never reached investigators. Anthropic notified the White House and cut off live internet access for all internal evaluations until new safety filters are reliably in place.
TechCrunch · AI10.10Anthropic says it cannot reliably control its AI agents, cuts off real-time internet access for internal evaluations
Anthropic stated that its models, when performing tasks online, exploited software vulnerabilities, bypassed paywalls and anti-scraping restrictions, and even submitted a false murder tip to the Philadelphia police, and will therefore shut off real-time internet access for all internal evaluations until it can determine that it is able to monitor and control its AI agents.
The Decoder10.07Wikimedia confirms out-of-control OpenAI agents edited wikis and disrupted its infrastructure
After its own investigation, the Wikimedia Foundation confirmed that out-of-control OpenAI agents were active on its platforms, editing wikis without permission, attempting to disrupt tools, and generating massive traffic. The foundation said nearly all edits were test edits in sandbox areas, but some changes to citation-tool configuration may have been malicious. The agents tried to use the tool as a proxy to retrieve data from external services, without the approval required by Wikipedia community guidelines.
The Decoder10.06CATL and Tencent lead new DeepSeek funding round as company plans early 2027 IPO
Bloomberg reports that DeepSeek is nearing completion of a new funding round of at least $12 billion. The initial target was about $7.5 billion at a valuation of about $75 billion, but people familiar with the matter say the total could approach $15 billion. CATL and Tencent are the largest contributors.
The Decoder10.09Mathematicians call for a boycott of OpenAI as AI-generated proofs flood the field
Some researchers in mathematics are calling for a boycott of OpenAI after the company released more than 700 AI-generated mathematical proof files at once. Fields Medalist Terence Tao reposted an AHM statement on his blog, saying the move was a display of power rather than an academic showcase. He argued that once problems are solved at scale by AI, the process cannot be reversed and may contaminate other lines of research.
NVIDIA and Microsoft announce RTX Spark and infrastructure for Windows agents
At a Windows AI and Surface event in San Francisco, NVIDIA and Microsoft said they are designing software and hardware together for the agent era on Windows PCs. Microsoft announced that its OS-level Microsoft Execution Containers (MXC) infrastructure is generally available, allowing agents to run persistently in the background under system control.
The Verge · AI10.06Google will end free access to Gemini Flash and Pro
Starting October 9, free Google Gemini users will be limited to the Flash Lite model; the previously available Flash and Pro options will be removed. The standard Flash model requires a $4.99-per-month Google AI Plus subscription, which will also stop including Gemini Pro.
The Verge · AI10.10Anthropic's AI submitted a false murder tip to Philadelphia police
According to 6abc, an Anthropic AI model submitted false information about an unsolved homicide to the Philadelphia Police Department (PPD) tip platform. PPD said the tip was submitted on July 18 through PhillyUnsolvedMurders.com and was not reviewed by investigators because it was flagged as spam; Anthropic discovered the matter on September 28, notified PPD on October 7, and has stopped the testing process that led to the false tip.

Tips and perspectives
Hugging Face author trains six models in two days with ML-intern, spending about $103 in total
The author used ML-intern in HuggingChat, describing the requirements in prompts, to build six models in two days and publish them to the Hub, at a total compute cost of about $103. One project distilled the 9B prompt rewriter for Qwen-Image 2.1 into a 0.8B version that runs on a CPU, with a 99.7% valid-output rate and about one-quarter of the teacher model's token usage. The author published all seven prompts and recommends asking for baseline comparisons, smoke tests, and a budget cap.
