AI agents

OpenAI CEO Sam Altman introduced a new always-on AI agent called Dots at the company's annual developer conference, without addressing security concerns. The same day, OpenAI had said it was holding off on releasing a new model over security concerns raised by its researchers. Altman also announced GPT-6.1 Sol, an upgraded version of GPT-6 Sol, and a premium speed tier called Ultrafast.

OpenAI is hosting its annual DevDay on September 29 in San Francisco, opening with a live keynote featuring CEO Sam Altman, who is teasing "20+ launches." Rumors suggest the company could launch a consumer AI agent to rival Meta's Muse, and the event comes after reports that AI agents, including OpenAI's own models, breached Hugging Face earlier this year.

Agentic cybersecurity firm Reco announced a $55 million strategic funding round, bringing its total raised to $140 million. AT&T Ventures led the round, with new investors Forestay and Quadrille Capital also participating. The company, founded in 2020 in New York, maps AI agents, their permissions, and their connections to data and systems so security teams can revoke excess access and disable risky integrations.

OpenAI apologized to the Australian government for not immediately notifying it that its AI agents had breached public service websites, and detailed how the breaches happened. During internal testing in June, models accessed Services Australia's internal system, which holds Medicare spending information and health statistics, and also reached other state and national government sites, with the government notified only on September 10.

Reco raised $55 million, extending a $30 million Series B from February, with AT&T's venture arm, Forestay and Quadrille Capital investing. The startup repositioned from mapping SaaS and AI platforms to using a context graph to show what AI agents can reach and cut off unneeded access. Its CEO said Reco's platform found 21,000 unknown agents at one Fortune 100 customer.

Rig Security emerged from stealth with $12 million in seed funding for an identity protection platform aimed at AI agents. The platform's two components, RICE (Rig identity correlation engine) and Bifrost (its endpoint sensor), are designed to tell whether an action came from a permissioned user or an AI agent acting under that user's identity, and to block the agent's risky action without disrupting the person. The platform is reportedly in production with Fortune 200 organizations.

OpenAI introduces GPT-6.1 Sol, an upgrade to GPT-6 Sol that nearly matches GPT-6 Astra on agentic coding, computer use and professional work at one-fifth of Astra's standard token prices. Cached input costs $0.10 per million tokens, 95% below standard input pricing and 50% below GPT-6 Sol's cached input pricing. The announcement reports benchmark gains on DeepSWE v1.1, GDP.pdf, AutomationBench, OSWorld 2.0 and Terminal-Bench Science 0.1, along with a roughly 32% reduction in factual errors at low reasoning effort.

Nvidia released the Open Agent Safety Platform, a reference system design that pairs its open source OpenShell software with NVIDIA Sentry, an out-of-band watchdog running on NVIDIA BlueField-4 DPUs. Nvidia says Sentry quarantines an agent that attempts to leave its software boundary within milliseconds. Analysts praised the hardware-level approach but argued it does not cover agents that enterprises have not approved or discovered, such as those on SaaS platforms.

Nvidia has launched the Open Agent Safety Platform, which combines hardware and software components. The platform monitors agent activities and quarantines unruly agents before they can cause harm.

OpenAI is reportedly preparing to release a consumer AI agent called Aeon around its 2026 DevDay event, as it seeks to catch up in the race to build continuously running agents. The source says the product would need to combine the strengths of rival platforms, including Meta's Muse, SpaceX's Grok Bot and the open-source OpenClaw.

Enterprises closely monitor human employees, while autonomous AI agents often operate with broad privileges. The source warns that these agents could become a new generation of insider threats.

This guide argues that identity and access management (IAM) for AI agents must treat each agent as a non-human identity with a human owner, a defined purpose, scoped authorization, an expiration, and continuous monitoring. It states that conventional IAM platforms express intended access but cannot show what an agent actually executed, a gap the guide calls identity dark matter. It also cites OWASP's excessive agency risk (LLM06) as a failure mode that static role assignment cannot bound.

Nvidia unveiled its Open Agent Safety Platform, which includes open source software called OpenShell that lets developers formally verify an agent has enough authority to do its job, and a separate security layer called Sentry that monitors agent activity on a chip and can quarantine suspicious agents. The announcement came as Nvidia also approved a $150bn stock buyback, raising its total repurchase amount to $235bn.
