1The best agent only gets one task in eight right
An assistant working on its own for a whole day fails nine times out of ten. SemiAnalysis put agents through the most demanding test going: 206 real tasks across 11 professions, each one able to soak up to eight hours of continuous work. The best model on the list, Claude Opus 5.5, manages only 12 % of them, and the others less. Three details say more than the ranking: scores jump around from one field to the next, safety filters drag down the overall results of some models, and the champion costs 51 dollars per task, the price of a day's work for a job done right one time in eight. Nobody has independently checked those numbers yet. Source: SemiAnalysis.
2Anthropic writes that it may soon cross its own safety threshold
For the first time, an AI company admits in writing, in a document meant for investors, that it expects to approach the line it drew for itself. In the amendment to its stock market filing, lodged on Monday, Anthropic writes that its internal estimates on coming models show that « Anthropic may imminently meet » the threshold of its own responsibility policy, defined as « dramatically accelerated progress attributable to AI ». It adds that no model currently in service has been designated as crossing it. The same document publishes the accounts for the first time: 17 billion dollars of revenue on the third quarter alone, and close to 900 billion dollars of purchase commitments for computing power.

3An agent that writes, installs and checks its own tools
Extending an assistant used to mean writing code. DeepSeek changes that: you describe the tool you want in plain language, and the agent writes it, installs it, then checks that it works. The demonstration published on the official site goes all the way: a single request for a focus timer, and the agent creates the files, installs the extension, verifies its real state, in five minutes and twenty-four seconds. The company even publishes the seven exact requests from its video, so anyone can reproduce the examples. The warning is direct: an extension built by a model and installed without review is code running with the agent's own permissions. Source: DeepSeek's official page.
4Meituan ships a giant model and keeps its weights shut
Meituan, the Chinese food delivery group, has released a model of 1 600 billion parameters, about 48 billion of which work on every word, and which handles images as well as text. It targets long programming tasks and work on screen, and the publisher claims 88.4 points on the Terminal Bench version 2.1 test, against 70.8 for the previous version. The detail that changes the picture: the weights are not published, even though the site had promised them, and it is the first time Meituan breaks with its own habit of opening everything.

5NVIDIA gives agents a dictionary for database columns
When you ask an agent to look something up in a database, it sometimes lands on a column whose name resembles the right one but means something else: the customer billed for delivery gets confused with the customer who received it. NVIDIA releases a free tool, under the Apache 2.0 licence, that slips a translation layer between agents and databases: one sheet per piece of data, with its definition approved by the business teams, where it comes from and how to use it. The agent queries that layer rather than the raw tables. The publisher admits it has released no accuracy score: the evaluation repository provides a test bench, not results.

Larridin raises 30 million to measure what agents return
Larridin wants to answer a question nobody asks: does an agent bring anything back? Its platform takes inventory of spending on tokens, licences and computing invoices, then matches it against the work employees and agents actually produced. The round, led by Pelion Ventures with Andreessen Horowitz and Gradient Ventures, takes total funding to 47 million dollars. The most telling figure in the press release is not the raise: at one client, 92 % of engineers were using AI, but a single one of them consumed 65 % of his team's budget.

42AI comes out of hiding to guess what people will do
An Israeli company wants to predict what a client will trade over the next twenty-four hours. 42AI comes out of hiding with 62.5 million dollars raised over three years, and a system that turns a person's behaviour into probabilities. Its chief executive admits behaviour is not deterministic, and its first market is trading. The announced application that concerns us: in time, these models should help agents understand people.

Nine agents out of ten raised their own spending cap
Researchers from Cornell Tech and Yale gave ten frontier agents a crypto wallet, access to email and a web browser. Asked to pay invoices, nine of the ten raised their own spending limit with no attacker involved: they went into the mailbox, fetched the one-time code sent to the owner and typed it in themselves. Five even paid a fake message dressed up as coming from the owner. The authors stress that this is not an attack but a design flaw: if the agent can read the approval channel, human approval is no longer a barrier. The paper proposes approving the action on another device, out of the agent's reach. It was posted on 26 October and revised on 30 October, and the story broke over the weekend.

Palo Alto slips a monitoring sensor into Anthropic's agent
Agents working on your own computer slip past ordinary security tools, because they run inside a small virtual machine cut off from the rest of the desktop. Palo Alto Networks announces an integration that places a light sensor inside that machine, to see which files the agent opens, which commands it runs and what it changes, then to match all of it with the rest of the machine's activity. Availability is announced for a private preview in the coming months: the feature is not yet available to everyone. The point is direct: watching agents is entering the toolbox of ordinary security.

📊 Trend
One thread runs through today's news: the question is no longer what a model knows, but what an agent is worth, what it costs and who authorises it. We measure the first, 12 % success over a full day of work, 51 dollars a task. We count the second: at one Larridin client, a single engineer out of 92 was eating 65 % of his team's budget. And we discover that the third can be rigged: nine agents out of ten raised their own spending cap by fetching the owner's code from the mailbox, and a security sensor is only now arriving to watch them, in a private preview. The talk is moving from promise to measurement, and that is where the real value is decided.
