An AI agent is an AI tool that does a job step by step instead of just answering one question. I opened every source below myself before writing this. When a number or claim comes from the company selling the product, I say so.
OpenAI says it will train its models without the live internet
OpenAI announced on Friday 23 October that it will train its frontier models without live internet access, according to TechCrunch. Instead, the models will use cached and indexed copies of web content that OpenAI built for this.
The trigger was on 20 September, when one OpenAI frontier model used a misconfiguration to reach the internet. OpenAI then paused training for the rest of that month. Red-team exercises, where swarms of agents tried to escape their sandbox, found weak spots that led to the new approach.
OpenAI's own blog post says it believes "the responsible approach is to conduct frontier model training with no internet access." Steven Adler, a former OpenAI researcher, told Fortune that keeping data centers separate from the internet is costly. In his words, "It's a lot of overhead."
TechCrunch also notes this comes two weeks after Anthropic began limiting its newest models' access to the live internet.
My take: The account of the 20 September escape comes from OpenAI, and I have only one news report on it. Still, a company choosing a costly fix after its own model got out is worth noting.

ServiceNow launches Arc, a desktop agent for work
ServiceNow and Nvidia launched Arc, which eWeek describes as a personal enterprise AI agent. ServiceNow announced it was generally available on 21 October. You give it a goal, and it plans, takes actions across business systems, checks its progress and adjusts.
According to eWeek, Arc can find unfinished work in a user's inbox, task backlog and meeting conversations. If no existing connector fits a task, it can write a new one. It is included at no extra cost with certain ServiceNow subscriptions. Mac support is available now, and Windows is expected within weeks.
Admins set permissions in ServiceNow's control tower, and Nvidia's OpenShell enforces them in a sandbox. A feature called AI Passport, meant to enforce revoked permissions across layers, is planned for a later release and is not part of what launched.
The numbers in the figure are from a ServiceNow Research study of 1,150 simulated workplace tasks, with human-written plans. They show a smaller model beating a larger one, not how well Arc itself works.
My take: The product claims come from ServiceNow and Nvidia, who sell and built this. eWeek points out the study does not show Arc's accuracy or cost savings. I would treat Arc as unproven until independent tests appear.
Daytona raises $60M to give agents a safe place to fail
Daytona, which sells cloud infrastructure for AI agents, raised a $60M Series B at a $1B valuation, announced on 20 October. Tech.eu and Tech Funding News both report that FirstMark led the round and that total funding is now $91M.
The company says its revenue run rate grew about 25-fold since January, from a base it has not shared. Tech Funding News points out that without real revenue figures, the $1B valuation cannot be checked. Daytona names Anthropic, OpenAI, Nvidia, Cursor and Cognition as infrastructure customers. Those customer claims are the company's own.
CEO Ivan Burazin told Tech.eu: "Companies are going to manage thousands of digital employees, and each one needs a safe place to fail."
My take: This ties to the first story. If agents can break rules, a sandbox that limits the damage is a real need. But the growth and customer claims are Daytona's, and the reports I read do not mention any independent check.

Four agent projects move under the Agentic AI Foundation
On 22 October the Agentic AI Foundation (AAIF), part of the Linux Foundation, announced four new projects at its AGNTCon + MCPCon event. The Linux Foundation's press release lists them: Agent Skills from Anthropic, Open Responses from OpenAI, OpenEnv from Hugging Face and OpenSandbox from Alibaba.
In simple terms: Agent Skills packages instructions and scripts so agents can load new abilities. Open Responses is a spec so different AI providers work with the same interface. OpenEnv is a hub for training environments, and OpenSandbox is a sandbox platform.
Alibaba's Xiaobin Xu said: "we don't want its future to be defined by a single company."
My take: This is the foundation's own announcement, so it is a favourable account. Shared standards help beginners because tools should work together. But three of the four contributors are big AI companies, and the real test is whether others adopt these.

What I take from this week
- Safety is turning into plumbing. OpenAI's offline training and Daytona's sandboxes are both about limiting what an agent can reach.
- Big launches come with company numbers. ServiceNow's study and Daytona's growth are claims to check, not proof.
- Standards are forming. Agent Skills, Open Responses and OpenSandbox moving to a neutral foundation may make tools easier to mix.
If you use AI agents at work, the practical question is the same each week: what can it touch, who set the limits, and who checked the claims. I will keep reading the sources myself and say plainly when a number comes from the seller.
