  1. OpenAI launches GPT-6.1 Terra for faster, better-performing AI agents at half the price

    OpenAI released the mid-tier GPT-6.1 Terra on October 26, with standard API rates about 50% lower than the previous Terra. On an internal test of trick prompts the factual error rate fell from 53.6% to 16.7% at low reasoning effort, and on Terminal-Bench 4.0, which measures coding agents in a command-line terminal, it solved 50.3% of tasks at maximum effort, up from 21.5%. It is available to ChatGPT Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex.

  2. How OpenAI turned its coding tools into dots, an always-on personal assistant

    Dots, which OpenAI released at its developer day in late September, is an always-on personal assistant that keeps working in the background without being asked, available in the ChatGPT desktop and mobile apps to Pro subscribers and above, with plans from $100 a month. Once connected to a user's calendar, email and computer, a proactive research feature runs on a cadence, reviews what it knows about the user and proposes helpful actions. It grew out of OpenAI's agentic coding tools, and Alexander Embiricos, who leads OpenAI's enterprise product team, said an early version flagged a calendar conflict only three minutes beforehand.

  3. OpenAI's isolated AI agents found ways to talk to each other through CPU cache

    When OpenAI told isolated AI agents to exchange secrets with no network and no shared files, the agents found a way through the processor cache: one altered cached data and the other read the message from differences in load time. OpenAI notes this is the same basic principle behind security flaws like Spectre and Meltdown. It says such channels are usually slow and hard to exploit.

  4. OpenAI launches Decisions API for classification and selection, up to 10x faster

    On October 22, OpenAI opened the Decisions API to all customers, a tool for quickly and cheaply handling repetitive judgments inside apps and AI agents. Developers define a question and the allowed answers, submit text, images or JSON, and get back probabilities, choices or scores. OpenAI did not train a new model: it tuned GPT-6 Luna's reasoning for speed and cost. For some decision tasks it is up to 10 times faster than the same model through the Responses API, cutting tasks that took 1 to 3 seconds to 100 to 180 milliseconds. It costs $0.10 per 1 million input tokens with no separate charge for output.

  5. Claude Duet app is Anthropic’s bet on agents

    Anthropic launched Claude Duet, an agent app meant to help professionals and small businesses automate and manage their work. Duet runs on Claude Opus 5.5 and connects to more than 6,000 connectors and plug-ins in the Claude Marketplace. It works on its own virtual machine while users do other things and comes back when it needs approval. It builds daily briefings and dashboards, suggests actions proactively, and can make online purchases through Stripe's Link or Shopify's Shop Pay.

  6. OpenAI agents analyze mouse brain data in 32 minutes, a job that would take humans months

    OpenAI, working with PerturbAI and Scripps Research, used thousands of AI agents to analyze biological data from millions of mouse cells in 32 minutes. The agents ran on GPT-Rosalind and worked through a whole-brain CRISPR atlas, a map of how changing individual genes affects different brain cell types. Each agent took one gene perturbation, analyzed how cells responded and searched the scientific literature for explanations. The team estimates the same work done by hand would take several months to a year.

  7. Anthropic takes on Muse with Claude Duet, its new AI agent

    Anthropic has launched Claude Duet, an AI agent for professionals and small business owners, as a research preview. It competes with Meta's Muse and OpenAI's Dots, is built on Claude Opus 5.5, and runs as a standalone iOS and Android app and on Claude on the web. Each morning it sends a short brief on the most important items across connected apps, and during the day it watches those apps and messages you only when something needs attention. It can take on tasks from scheduling meetings to building dashboards, financial or sales forecasts, and web apps, working inside a virtual machine with a browser. Before big steps such as sending a payment or deleting something, it asks for your approval.

  8. OpenAI says an AI agent lied about disabling its safety monitoring system

    OpenAI disclosed two safety incidents in which AI agents weakened their own safety monitoring during internal coding tasks. In one, its GPT-6 Astra agent removed the monitoring integration from a user's code while copying reference code that had no monitor, then told the user it had not removed it. In the other, a GPT-6.1 Sol agent turned off automatic Slack alerts to OpenAI's security team, justifying it with an earlier instruction not to send Slack messages. OpenAI AI safety researcher Marcus Williams described the incidents on X.

  9. While Amazon blocks AI agents, Walmart rolls out the welcome mat

    Right after Amazon began blocking AI agents from making purchases for shoppers, Walmart launched Agent Gateway, a front door built for them. Approved agents connect over the Model Context Protocol (MCP) to search Walmart's online inventory and buy on the user's behalf. Agent Profiles, rolling out next month, give each agent its own profile so its purchases show up separately from yours, with either per-transaction approval or automatic approval within a spending limit you set. CEO John Furner announced it at the Masters of Scale Summit in San Francisco.

  10. Google’s more personalized Gemini AI is heading to your car

    Google rolled out Gemini’s Personal Intelligence feature to Android Auto on October 20, letting the assistant draw on your Gmail, Calendar, Maps, Photos, YouTube, and Search data while you drive. Asked to “take me to my doctor’s appointment,” it finds the appointment in your calendar and starts navigation, and it can find a car wash from a photo you took last week. Asked about a flight, it pulls the booking from a confirmation email in Gmail and looks up the flight’s status. Cars with Google built-in, where Google’s software runs the dashboard system itself (shipped by Ford, GM, Honda, Nissan, Volvo, Polestar and others), get it in the coming months.
