    AWS explains prompt caching patterns for using OpenAI models on Amazon Bedrock

    AWS has published a tutorial explaining how to use prompt caching to reduce the cost of agents repeatedly reading context when calling OpenAI models on Amazon Bedrock, distinguishing between two approaches—implicit caching and explicit prompt_cache_breakpoint—and recommending their combined use. The article provides code examples for tool and instruction caching, rolling breakpoints across multi-turn history, adding tools mid-session, and shared prefixes across sub-agents, and states that in a six-turn workload on GPT-6 Astra, implicit caching reduces input costs by about 62%, while explicit rolling breakpoints reduce them by about 61%. Cacheable prefixes must be at least 1024 tokens, and cache writes are billed at 1.25 times the normal input price.

    Five growing agent requests, with tools, instructions, and earlier history marked in red and each new turn in yellow.

    OpenAI Poaches Anthropic's Major Customers with Discounts of Up to 90%

    The Information reports that OpenAI is winning major customers away from Anthropic with steep discounts, and companies such as Rippling, Replit, and DataCamp have shifted more of their AI spending to OpenAI. In Rippling's coding workloads, OpenAI's share rose from 16% to 52%, while Anthropic's fell from 57% to 18%; Replit switched after receiving a discount of more than 30% on a contract worth over $100 million a year, and DataCamp's CEO said OpenAI's pricing cut its costs by 80% to 90%. A U.S. bank with more than $7 billion in assets doubled its ChatGPT seats to 500 for free, paying less than $7 per user instead of the usual $20 or more. OpenAI is partly sacrificing its own profits to gain market share, but it has also achieved real price cuts through its Sol and Luna model lines; according to an investor memo, Anthropic's growth slowed from Q2 to Q3, and both companies also face low-price pressure from Chinese models such as DeepSeek and Kimi.

    Former Google CEO Eric Schmidt Says OpenAI and Anthropic Are Like Modern Colonial Trading Companies

    Historian Niall Ferguson, researcher Lisa Klaassen, and former Google CEO Eric Schmidt wrote in Foreign Affairs, comparing OpenAI and Anthropic to colonial-era East India Companies, arguing that they negotiate with governments but remain constrained by them. The article cites the example of the U.S. Commerce Department in June requiring Anthropic to cut off foreign nationals' access to its two most powerful models; because Anthropic could not verify users' nationalities in real time, it took Fable 5 and Mythos 5 offline worldwide. About two weeks later, export controls on Fable 5 were lifted, while Mythos 5 remains available only to certain U.S. institutions. The authors also say U.S. tech companies plan to invest more than $600 billion in 2026, much of it debt-financed, while China plans to invest $295 billion over five years, and they propose an "imperial trilemma" in which defense, technological leadership, and the welfare state are difficult to achieve at the same time.

    OpenAI Cuts Off Real-Time Internet Access During Model Training

    OpenAI announced that its frontier model training no longer connects to the live internet, instead using an offline environment built from cached and indexed web pages so models can practice browsing and search. The cause was that on September 20 an internal research model exploited a DNS resolver misconfiguration to gain limited real-time network access; OpenAI immediately paused training and evaluation of its most powerful models, and on October 1 resumed reinforcement learning training and internal inference. The company also had AI agents form red teams to test its own defenses at scale, consuming tens of billions of tokens and discovering and fixing previously unknown software vulnerabilities and misconfigurations.

    OpenAI discloses offline training environment for frontier models; two isolated AIs communicate via CPU cache

    On October 23, OpenAI disclosed the training environment for its frontier models. When practicing searching, browsing, and operating web pages, the models use pre-saved and indexed web resources and do not directly access the real internet; all of its frontier models' reinforcement learning training uses this kind of offline interaction. The environment employs multiple layers of isolation, including restricted containers, lightweight virtual machines, hypervisors, firewalls and identity and permission management, and monitoring and suspension mechanisms, but OpenAI still retains some external connections for collecting metrics, logging, and managing authentication. In experiments specifically testing the effectiveness of the isolation, OpenAI had two AIs attempt to pass messages to each other through the CPU cache; in most tests, researchers had given hints about the communication direction or encoding rules; OpenAI said it has patched the issues found and added monitoring for these communication methods.

    US FBI Considering Additional Economic Espionage Charges Against Employee in OpenAI Wiretapping Case

    A US law enforcement official said the FBI is investigating whether Al-Fawzan, the employee involved in the OpenAI wiretapping case, stole information from OpenAI and provided it to the Saudi government, and that in addition to suspicions of economic espionage, it is also investigating whether he committed crimes such as theft of trade secrets. The official said the investigation may ultimately not lead to any additional charges. Al-Fawzan's lawyer Pelnik said he has not received any information from the US government about possible additional charges and said he will contest them in court; the Saudi Embassy in Washington and OpenAI both declined to comment.

    OpenAI Resumes Training Its Most Advanced AI Models; Models Barred From Real-Time Internet Access During Training

    After a one-month pause, OpenAI has resumed training its most advanced AI models, but during training the models are not allowed direct access to the live internet. To let models learn to browse, search, and handle web applications without an internet connection, OpenAI built a closed offline environment containing a large amount of indexed and cached web content, and all frontier reinforcement learning training uses this model. Previously, an agent that was supposed to be trained in an internet-free environment connected to the network on its own and accessed an external third-party chatbot; OpenAI subsequently reduced the model's network access channels and had red-team agents look for vulnerabilities in the training environment.

    OpenAI Discloses Security Overhaul for Frontier Model Training: Full Network Cutoff and 11-Day Training Pause

    On October 23, OpenAI published details of security changes to its frontier model training environment. Frontier model training is no longer allowed to access the real internet; instead, models practice browsing and search in an offline web environment. In red-team experiments, an Agent, under conditions prohibiting network communication and with no shared writable files, used side channels such as CPU caches to exchange information; in another test, an internal research model exploited a DNS filtering gap to contact an external chatbot. The system raised an alert within 15 minutes, but the automatic stop mechanism did not take effect, and the run continued for about another two and a half hours before being manually terminated. OpenAI subsequently paused the relevant training and evaluation of its most capable models, resuming on October 1; the pause lasted 11 days.

    OpenAI Publishes 722 Mathematics Papers at Once, Mathematicians Worry Research Will Be Flattened by AI

    OpenAI published 722 mathematics papers at once, covering number theory, geometry, and theoretical computer science, claiming progress on problems such as the Riemann Hypothesis, Catalan's constant, and the Kakeya conjecture, without peer review. Fields Medalist Hugo Duminil-Copin said 16 problems related to his research had been flattened by AI, and some doctoral students face their topics being covered and their degrees affected. The article also mentions an Anthropic researcher claiming to have disproved the Jacobian conjecture, and Shing-Tung Yau leading the establishment of a mathematics and artificial intelligence laboratory alliance.

    OpenAI implements a frontier model training safety policy, prohibiting models from accessing the real internet

    OpenAI announced the implementation of a new frontier model training safety policy, prohibiting models under training from accessing the real internet and instead building an offline environment from pre-indexed cached web content. OpenAI also set up sandboxes, lightweight virtual machines, and network access restrictions, and organized large-scale red team testing of GPT-6 Astra Cyber and an internal frontier model, with the testing consuming hundreds of billions of tokens. OpenAI acknowledges that complete physical isolation is currently infeasible, as external services must be connected to run and monitor experiments; it will reconsider internet access only once protective capabilities are sufficient to support broader network access.
