Oil Rises as Iran Talks Stall

Oil rose after Iran’s foreign minister downplayed prospects for a breakthrough in nuclear talks with the US, saying no formal proposal had been received. Brent advanced more than 1% to settle above $65, while West Texas Intermediate climbed to top $62. “Iran has not received any written proposal from the United States, whether directly or […]

Oil rose after Iran’s foreign minister downplayed prospects for a breakthrough in nuclear talks with the US, saying no formal proposal had been received.

Brent advanced more than 1% to settle above $65, while West Texas Intermediate climbed to top $62.

“Iran has not received any written proposal from the United States, whether directly or indirectly,” Foreign Minister Abbas Araghchi said in a post on X. “In the meantime, the messaging we — and the world — continue to receive is confusing and contradictory.”

Prices had slumped Thursday when US President Donald Trump suggested the two sides were closer to a deal, which could pave the way for some extra supply from Iran. But those barrels would have a limited effect on a market already bracing for a surplus.

“Much of the trading action feels reactionary, with geopolitical headlines swinging crude up or down by a few dollars,” said Rebecca Babin, a senior energy trader at CIBC Private Wealth Group. “Positioning ahead of the weekend is also likely contributing to today’s move, as traders reduce risk in the face of ongoing uncertainty.”

The International Energy Agency on Thursday reiterated that it expects an increase in new production worldwide to exceed demand growth this year and next, creating a global glut. The excess supply may be even bigger if the Organization of the Petroleum Exporting Countries and its partners confirm further output hikes.

“We wouldn’t overstate the impact on Iranian supply here — a deal might add 200,000 to 300,000 barrels a day to Iranian exports, which isn’t enormous,” said Robert Rennie, head of commodity and carbon research at Westpac Banking Corp. “We maintain the view that Brent should remain in a $60 to $65 holding pattern in the weeks ahead.”

Oil also climbed on reports that Israel struck Houthi-held areas in Yemen, including ports. The escalation raised fears of broader regional conflict, especially after Prime Minister Benjamin Netanyahu warned further military action is imminent.

Oil has now gained for the second straight week, after rising on the détente in the trade conflict between the US and China, the world’s biggest crude consumers.

Prices are still down more than 10% this year because of the twin hit of trade uncertainties and faster-than-expected output increases by OPEC+.

Oil Prices

West Texas Intermediate climbed 1.4% to settle at $62.49 a barrel in New York.
Brent rose 1.4% to settle at $65.41 a barrel.

How AWS is reinventing the telco revenue model

Consider what that means for the mobile operator and its relationship with its customers. Instead of selling a generic 5G pipe with a static SLA, a telco can now sell a dynamic, guaranteed slice for a specific use case—say, a remote robotic surgery setup or a high-density, low-latency industrial IoT

What’s the biggest barrier to AI success?

AI’s challenge starts with definition. We hear all the time about how AI raises productivity, and many have experienced that themselves. But what, exactly, does “productivity” mean? To the average person, it means they can do things with less effort, which they like, so it generates a lot of favorable

IBM proposes unified architecture for hybrid quantum-classical computing

Quantum computers and classical HPC are traditionally “disparate systems [that] operate in isolation,” IBM researchers explain in a new paper. This can be “cumbersome,” because users have to manually orchestrate workflows, coordinate scheduling, and transfer data between systems, thus hindering productivity and “severely” limiting algorithmic exploration. But a hybrid approach

Energy Department Approves Immediate Additional LNG Exports from Plaquemines LNG

WASHINGTON—U.S. Secretary of Energy Chris Wright today authorized an immediate 13% increase in exports at Venture Global’s Plaquemines liquefied natural gas (LNG) Terminal in Louisiana. Today’s signed export authorization allows additional exports of up to 0.45 billion cubic feet per day (Bcf/d) of U.S. natural gas as LNG to non-free trade agreement (FTA) countries from the Plaquemines LNG Terminal. With today’s order, Plaquemines LNG is now authorized to immediately export a total of 3.85 Bcf/d to both FTA and non-FTA countries, strengthening global natural gas supplies with reliable American LNG. “At a time when Iran and its terrorist proxies attempt to disrupt the global energy supply, the Trump Administration remains committed to strengthening American energy dominance,” said Secretary Wright. “Thanks to President Trump and American innovators, the U.S. is not only the largest producer and exporter of LNG but will more than double its LNG exports in the coming years. We will see meaningful additions to U.S. LNG export capacity at Plaquemines immediately and other facilities commencing operations in future weeks and months.” “Our mission to enable secure, reliable, and affordable energy has never been more important than now,” said Kyle Haustveit, Assistant Secretary of the Hydrocarbons and Geothermal Energy Office. “I am pleased that DOE can take this action to be able to make an immediate difference to help add to global supplies of LNG.” Plaquemines LNG commenced exports in December 2024 and has rapidly been able to increase its export levels to over 3 Bcf/d. This authorization will allow for an immediate increase in the volumes of LNG that Plaquemines LNG can export to non-FTA countries, which import the majority of U.S. LNG. Thanks to President Trump’s leadership and American innovation, the United States is the world’s largest natural gas producer and exporter. Since the President ended the

Secretary Wright Directs Sable Offshore to Restore the Santa Ynez Unit and Pipeline

WASHINGTON—U.S. Secretary of Energy Chris Wright today directed Sable Offshore Corp. to restore operations of the Santa Ynez Unit and Santa Ynez Pipeline System to address supply disruption risks caused by California policies that have left the region and U.S. military forces dependent on foreign oil. This action issued under authorities provided by the Defense Production Act and delegated through Executive Order, “National Defense Resources Preparedness,” as amended by President Trump’s Executive Order, “Adjusting Certain Delegations Under the Defense Production Act.” “The Trump Administration remains committed to putting all Americans and their energy security first,” Secretary Wright said. “Unfortunately, some state leaders have not adhered to those same principles, with potentially disastrous consequences not just for their residents, but also our national security. Today’s order will strengthen America’s oil supply and restore a pipeline system vital to our national security and defense, ensuring that West Coast military installations have the reliable energy critical to military readiness.” Sable’s facility can produce approximately 50,000 barrels of oil per day, a 15 percent increase to California’s in-state oil production, that can replace nearly 1.5 million barrels of foreign crude each month. California once supplied nearly 40 percent of U.S. oil production, but decades of radical state policies targeting reliable energy sources have driven a decline in domestic output while fuel demand remains among the highest in the nation. Today, more than 60 percent of the oil refined in California comes from overseas, with a significant share traveling through the Strait of Hormuz—presenting serious national security threats. Unlike other regions of the country, California remains largely disconnected from interstate crude pipelines that move American oil to refineries across the United States. The action also prioritizes pipeline transportation capacity to ensure crude produced offshore California moves through the Las Flores Pipeline System to Pentland Station

Energy Department Initiates Strategic Petroleum Reserve Emergency Exchange to Stabilize Global Oil Supply

WASHINGTON—The U.S. Department of Energy (DOE) today issued a Request for Proposal (RFP) for a crude oil exchange from the Strategic Petroleum Reserve (SPR) as part of the 172-million-barrel exchange announced earlier this week. This first RFP will be for 86 million barrels of crude oil. Under the terms of the exchange, companies will return the borrowed oil to DOE with additional barrels as a premium, strengthening the Strategic Petroleum Reserve while stabilizing markets at no cost to American taxpayers. Early deliveries are expected to begin moving to market by the end of next week. Barrels will be made available from the SPR’s Bryan Mound, West Hackberry, and Bayou Choctaw. Return barrels will be delivered back to DOE on a schedule designed to protect commercial markets and the American people, while ensuring the reserve remains a critical national security asset. “Today’s action reflects President Trump’s continued commitment to safeguarding U.S. energy security and contributing constructively to global market stability,” said Kyle Haustveit, Assistant Secretary of the Hydrocarbons and Geothermal Energy Office. “By participating in the coordinated international release, we are helping ensure that supply remains reliable during a period of heightened global uncertainty. We will continue to work closely with our partners to support a resilient energy system while maintaining the long‑term strength and readiness of the Strategic Petroleum Reserve.” The exchange is part of a coordinated international effort requested by President Trump, in which International Energy Agency member nations agreed to release 400 million barrels of oil from strategic reserves. The action comes as global oil supply routes face disruption from escalating tensions in the Middle East and attacks carried out by Iran and its proxies, threatening the reliable flow of energy through critical maritime corridors. Today, the SPR holds approximately 415 million barrels, up from roughly 395 million barrels one year

Energy Department Announces $500 Million to Strengthen Domestic Critical Materials Processing and Manufacturing

Funding will expand domestic manufacturing of battery supply chains for defense, grid resilience, transportation, manufacturing and other industries WASHINGTON—The U.S. Department of Energy’s (DOE) Office of Critical Minerals and Energy Innovation (CMEI) today announced a Notice of Funding Opportunity (NOFO) for up to $500 million to expand U.S. critical mineral and materials processing and derivative battery manufacturing and recycling. Assistant Secretary of Energy (EERE) Audrey Robertson is currently in Japan meeting with regional allies at the Indo-Pacific Energy Security Ministerial and Business Forum (IPEM) to advance shared efforts on supply chain resilience and energy security issues. Her engagements at IPEM underscore the importance of close cooperation with partners as the United States strengthens its supply chain through this NOFO. “For too long, the United States has relied on hostile foreign actors to supply and process the critical materials that are essential in battery manufacturing and materials processing,” said U.S. Energy Secretary Chris Wright. “Thanks to President Trump’s leadership, the Department of Energy is playing a leading role in strengthening these domestic industries that will position the U.S. to win the AI race, meeting rising energy demand, and achieve energy dominance.” “I am delighted to be in Japan meeting with our allies, underscoring the important connection between critical materials and energy security,” said Assistant Secretary of Energy (EERE) Audrey Robertson. “Critical minerals processing is a vital component of our nation’s critical minerals supply base. Boosting domestic production, including through recycling, will bolster national security and ensure the United States and our partners are prepared to meet the energy challenges of the 21st century.” Funding awarded through this NOFO will support demonstration and/or commercial facilities for processing, recycling, or utilizing for manufacturing of critical materials which may include traditional battery minerals such as lithium, graphite, nickel, copper, aluminum, as well as other

Energy Department Announces $1.9B Investment in Critical Grid Infrastructure to Reduce Electricity Costs

WASHINGTON—The U.S. Department of Energy’s Office of Electricity (OE) today announced an approximately $1.9 billion funding opportunity to accelerate urgently needed upgrades to the nation’s power grid. These investments will meet rising electricity demand and resource adequacy needs, while lowering electricity costs for American households and businesses. Projects selected through the Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades (SPARK) funding opportunity will deliver fast and durable upgrades to the grid with real results. In line with President Trump’s Executive Order, Unleashing American Energy, selected projects will demonstrate how reconductoring—replacing existing power lines with higher‑capacity conductors—paired with other Advanced Transmission Technologies (ATTs) can expand grid capacity, increase operational efficiency, lower prices for consumers, and improve overall system reliability and security of the nation’s electric grid. “For too long, important grid modernization and energy addition efforts were not prioritized by past leaders,” said U.S. Secretary of Energy Chris Wright. “Thanks to President Trump, we are doing the important work of modernizing our grid so electricity costs will be lowered for American families and businesses.” “The United States must increase grid capacity to meet demand, and ensure the grid provides reliable power—day-in and day-out,” said OE Assistant Secretary Katie Jereza. “Through this SPARK funding opportunity, we will stabilize and optimize grid operations to strengthen it for rapid growth.” The SPARK opportunity builds on the Grid Resilience and Innovation Partnerships (GRIP) Program, which provided up to $10.5 billion in competitive funding over five years to states, tribes, electric utilities, and other eligible recipients to strengthen grid resilience and innovation. The previous two GRIP funding rounds covered FY 2022-2023 and FY 2023-2024 funding. Today’s announcement continues the mission of the GRIP Program under the SPARK funding opportunity, focusing on the rapid deployment of reconductoring and other ATTs that expand transfer capability, strengthen reliability

United States to Release 172 Million Barrels of Oil From the Strategic Petroleum Reserve

WASHINGTON—U.S. Secretary of Energy Chris Wright released the following statement regarding the International Energy Agency (IEA) and the U.S. Strategic Petroleum Reserve (SPR): “Earlier today, 32 member nations of the International Energy Agency unanimously agreed to President Trump’s request to lower energy prices with a coordinated release of 400 million barrels of oil and refined products from their respective reserves. “As part of this effort, President Trump authorized the Department of Energy to release 172 million barrels from the Strategic Petroleum Reserve, beginning next week. This will take approximately 120 days to deliver based on planned discharge rates. “President Trump promised to protect America’s energy security by managing the Strategic Petroleum Reserve responsibly and this action demonstrates his commitment to that promise. Unlike the previous administration, which left America’s oil reserves drained and damaged, the United States has arranged to more than replace these strategic reserves with approximately 200 million barrels within the next year—20% more barrels than will be drawn down—and at no cost to the taxpayer. “For 47 years, Iran and its terrorist proxies have been intent on killing Americans. They have manipulated and threatened the energy security of America and its allies. Under President Trump, those days are coming to an end. “Rest assured, America’s energy security is as strong as ever.” ###

Data mining? Old servers could become new source of rare earths

For decades, he said, “the retirement of data center equipment was treated almost entirely as a compliance and disposal issue. Enterprises focused on secure decommissioning, certified recycling, and documented destruction of sensitive hardware. Once equipment left production environments, its economic life was assumed to be largely finished.” That assumption, he pointed out, “is beginning to change, because the hardware inside modern data centres contains a wide range of strategically important materials. Servers, storage systems, networking equipment, and power components contain copper, aluminum, silver, gold, and increasingly small but significant quantities of rare earth elements and other critical minerals.” These materials play a vital role in the manufacturing of semiconductors, energy systems, defense electronics, and advanced computing infrastructure, he explained, noting, “as global demand for digital infrastructure continues to expand, the volume of retired hardware entering disposal channels is rising quickly.” Electronic waste has already become one of the fastest growing waste streams in the world. “Global volumes now exceed 60 million tonnes annually and are projected to move toward eighty million tonnes by the end of the decade if current trends continue,” he said. “Data center infrastructure represents only a portion of that total, but it is a particularly important portion because it is concentrated, professionally managed, and replaced in structured cycles.” For a metals producer, he said, data center infrastructure represents a highly attractive feedstock, because unlike consumer electronics, enterprise hardware is replaced in large batches and flows through professional asset management channels. That predictability, said Gogia, “allows recyclers to design specialized processes that target specific components and materials. Over time, this creates the foundation for an industrial scale circular supply chain in which retired electronics feed back into the production of new materials.”

Meta is developing more AI chips for itself

With demand for AI chips rising and supplies tightening, Meta is taking its AI computing needs into its own hands and developing more of its own chips: It will produce four new generations of chips over the next two years. Cloud computing giants including Meta, AWS, and Google have been keen to develop their own chips to improve the performance of their own data centers. Meta started its own chip program in 2023, when it implemented the Meta Training and Inference Accelerator (MTIA), a family of custom-built silicon chips to power its AI workloads efficiently. The MTIA 300, which Meta will use for ranking and recommendations training, is already in production, Meta said. It will use the other planned chips, the MTIA 400, 450, and 500, mainly for generative AI inference production, it said.

Arista targets AI data centers with new liquid cooled pluggable optic module

To prove their point, the authors imagined a 400 MW AI datacenter with 1024 GPU racks of 128 GPUs each for a total of 128,000 GPUs. “Assume 12.8T scale-up and 1.6T scale-out bandwidth per GPU. With OSFP switch racks that have a density of 1.6 Pbps per rack, this would require more than 1,400 switch racks for scale-up and scale-out fabrics. With XPO, this would require 75% fewer racks, saving over 1,050 racks or 44 % of the floor space,” Bechtolsheim and Vusirikala stated in the blog. “Eliminating 75% of switch racks translates to massive reductions in construction and infrastructure costs, including power distribution, plumbing and installation costs, while accelerating deployment timelines,” Bechtolsheim and Vusirikala stated. Arista said the water-cooling capability of XPO is also an important feature. “All large AI data centers will be liquid cooled and the switches that go into these data centers also need to be liquid cooled,” Bechtolsheim and Vusirikala stated. “While one can add liquid cooled cold plates on flat-top OSFP modules, this does not substantially improve thermal performance.” XPO solves this problem by integrating a liquid cold plate inside the module, with two 32-channel paddle cards sharing the common cold plate which can cool both low power as well as high-power optics such as 8x1600G-ZR/ZR+ with up to 400W of power, Bechtolsheim and Vusirikala stated. XPO modules are much simpler than OSPF modules which improves reliability as well. “Each 32-channel paddle card has only one microcontroller and one set of voltage converters, a 75% reduction in common components versus 4 OSFPs,” Bechtolsheim and Vusirikala wrote.

Cisco grows high-end optical support for AI clusters

Cisco has also upgraded its Network Conversion System (NCS) with a 1RU, 800GE line card offering 12.8T capacity, with 32 OSFP-based ports for 100GE, 400GE, and 800GE clients and 800ZR/ZR+ WDM trunks. The NCS 1014 doubles the density of previous-generation NCS versions and now includes MACsec encryption (IEEE 802.1AE) to secure point-to-point links with hardware-based encryption, data integrity, and authentication for Ethernet traffic, Ghioni stated. It supports enhanced capacity and performance with C&L-band support and NCS 1014 systems with the 2.4T WDM line card based on the Coherent Interconnect Module 8 and now supports 800 GE clients, which can be mapped directly to a wavelength or inverse multiplexed across two wavelengths to maximize reach, Ghioni wrote. In the pluggable optic arena, Cisco is now offering a Quad Small Form Factor Pluggable Double Density (QSFP-DD) Pluggable Protection Switch Module that can monitor the optical link and switch traffic if it detects a fault in less than 50 milliseconds. The module occupies a quarter of the rack space compared to traditional protection devices—offering 90% rack space saving over available options, Ghioni wrote. It is aimed at Metro and DCI network customers where sub-50 ms failure recovery is essential and data centers needing fiber protection without bulky hardware, Ghioni stated. Cisco also added its Acacia developed Bright QSFP28 100ZR 0 dBm coherent optical pluggable in a standard QSFP28 form factor. It is aimed at edge, access, enterprise, and campus network deployment. Cisco has been actively growing its optical portfolio recently adding the Cisco Silicon One G300, which powers 102.4T N9000 and Cisco 8000 systems, as well as advanced 1.6T OSFP optics and 800G Linear Pluggable Optics.

Datalec targets rapid infrastructure deployment with new modular data centers

“We are engineering the data center with a new lens bringing pre-engineered system designs that are flexible and adaptable that enables a tailored solution for clients,” said John Lever, director of modular solutions at Datalec. The systems are flexible enough that these solutions cater for all types of data center, from standard server technology to AI and high-density compute. Datalec also provides “bolt-on” solutions, including a ‘digital wrapper’ including digital twinning and lifecycle and global support, Lever says. Another way Datalec says it differentiates from competing modular designs is a larger share of work is done offsite in a controlled manufacturing environment, which cuts onsite construction time, improves safety and limits disruption to live facilities, Lever says. The company competes with other modular data center vendors including Schneider Electric, Vertiv, Flex many others. DPI’s says its services are aimed at colocation providers, hyperscale and AI infrastructure teams, and large enterprises that need to add capacity quickly, safely and cost effectively across multiple regions.

Study finds significant savings from direct current power for AI workloads

The result is a 50% to 80% reduction in copper usage, due to fewer conductors and less parallel cabling, and an 8% to 12% reduction in annual energy-related OpEx through lower conversion and distribution losses. By reducing conductor count, cabling, and redundant power components, 800VDC enables meaningful savings at both build-out and operational stages. AI-first facilities can see a $4 million to $8 million in CapEx savings per 10 MW build by reducing upstream AC. For a one-gigawatt data center, you’re saving a couple million pounds of copper wire, he said. Burke says an all-DC data center is best done with a whole new facility rather than retrofitting old facilities. “[DC] is going to be in a lot of greenfield data centers that are going to be built, and data centers that are going to go to higher compute power are also going to DC,” he said. He did recommend all-DC retrofits for existing data centers that are going to employ high power computing with GPUs. Enteligent’s unnamed and as yet unreleased product is a converter that takes 800 volts and partitions it to 50 volts for the computing servers. The company will provide a new power supply, power shelf that converts 800 volts DC to 50 volts DC much more efficiently than any current power supplies. Burke said the company is doing NDA level testing and pilot programs now with its product, but it will be making a formal announcement within the next few weeks. There are a number of players in the DC arena focusing on different parts of the power supply market including Vertiv, Rutherford, Siemens, Eaton and many more.

Microsoft will invest $80B in AI data centers in fiscal 2025

And Microsoft isn’t the only one that is ramping up its investments into AI-enabled data centers. Rival cloud service providers are all investing in either upgrading or opening new data centers to capture a larger chunk of business from developers and users of large language models (LLMs). In a report published in October 2024, Bloomberg Intelligence estimated that demand for generative AI would push Microsoft, AWS, Google, Oracle, Meta, and Apple would between them devote $200 billion to capex in 2025, up from $110 billion in 2023. Microsoft is one of the biggest spenders, followed closely by Google and AWS, Bloomberg Intelligence said. Its estimate of Microsoft’s capital spending on AI, at $62.4 billion for calendar 2025, is lower than Smith’s claim that the company will invest $80 billion in the fiscal year to June 30, 2025. Both figures, though, are way higher than Microsoft’s 2020 capital expenditure of “just” $17.6 billion. The majority of the increased spending is tied to cloud services and the expansion of AI infrastructure needed to provide compute capacity for OpenAI workloads. Separately, last October Amazon CEO Andy Jassy said his company planned total capex spend of $75 billion in 2024 and even more in 2025, with much of it going to AWS, its cloud computing division.

John Deere unveils more autonomous farm machines to address skill labor shortage

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More Self-driving tractors might be the path to self-driving cars. John Deere has revealed a new line of autonomous machines and tech across agriculture, construction and commercial landscaping. The Moline, Illinois-based John Deere has been in business for 187 years, yet it’s been a regular as a non-tech company showing off technology at the big tech trade show in Las Vegas and is back at CES 2025 with more autonomous tractors and other vehicles. This is not something we usually cover, but John Deere has a lot of data that is interesting in the big picture of tech. The message from the company is that there aren’t enough skilled farm laborers to do the work that its customers need. It’s been a challenge for most of the last two decades, said Jahmy Hindman, CTO at John Deere, in a briefing. Much of the tech will come this fall and after that. He noted that the average farmer in the U.S. is over 58 and works 12 to 18 hours a day to grow food for us. And he said the American Farm Bureau Federation estimates there are roughly 2.4 million farm jobs that need to be filled annually; and the agricultural work force continues to shrink. (This is my hint to the anti-immigration crowd). John Deere’s autonomous 9RX Tractor. Farmers can oversee it using an app. While each of these industries experiences their own set of challenges, a commonality across all is skilled labor availability. In construction, about 80% percent of contractors struggle to find skilled labor. And in commercial landscaping, 86% of landscaping business owners can’t find labor to fill open positions, he said. “They have to figure out how to do

2025 playbook for enterprise AI success, from agents to evals

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More 2025 is poised to be a pivotal year for enterprise AI. The past year has seen rapid innovation, and this year will see the same. This has made it more critical than ever to revisit your AI strategy to stay competitive and create value for your customers. From scaling AI agents to optimizing costs, here are the five critical areas enterprises should prioritize for their AI strategy this year. 1. Agents: the next generation of automation AI agents are no longer theoretical. In 2025, they’re indispensable tools for enterprises looking to streamline operations and enhance customer interactions. Unlike traditional software, agents powered by large language models (LLMs) can make nuanced decisions, navigate complex multi-step tasks, and integrate seamlessly with tools and APIs. At the start of 2024, agents were not ready for prime time, making frustrating mistakes like hallucinating URLs. They started getting better as frontier large language models themselves improved. “Let me put it this way,” said Sam Witteveen, cofounder of Red Dragon, a company that develops agents for companies, and that recently reviewed the 48 agents it built last year. “Interestingly, the ones that we built at the start of the year, a lot of those worked way better at the end of the year just because the models got better.” Witteveen shared this in the video podcast we filmed to discuss these five big trends in detail. Models are getting better and hallucinating less, and they’re also being trained to do agentic tasks. Another feature that the model providers are researching is a way to use the LLM as a judge, and as models get cheaper (something we’ll cover below), companies can use three or more models to

OpenAI’s red teaming innovations define new essentials for security leaders in the AI era

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More OpenAI has taken a more aggressive approach to red teaming than its AI competitors, demonstrating its security teams’ advanced capabilities in two areas: multi-step reinforcement and external red teaming. OpenAI recently released two papers that set a new competitive standard for improving the quality, reliability and safety of AI models in these two techniques and more. The first paper, “OpenAI’s Approach to External Red Teaming for AI Models and Systems,” reports that specialized teams outside the company have proven effective in uncovering vulnerabilities that might otherwise have made it into a released model because in-house testing techniques may have missed them. In the second paper, “Diverse and Effective Red Teaming with Auto-Generated Rewards and Multi-Step Reinforcement Learning,” OpenAI introduces an automated framework that relies on iterative reinforcement learning to generate a broad spectrum of novel, wide-ranging attacks. Going all-in on red teaming pays practical, competitive dividends It’s encouraging to see competitive intensity in red teaming growing among AI companies. When Anthropic released its AI red team guidelines in June of last year, it joined AI providers including Google, Microsoft, Nvidia, OpenAI, and even the U.S.’s National Institute of Standards and Technology (NIST), which all had released red teaming frameworks. Investing heavily in red teaming yields tangible benefits for security leaders in any organization. OpenAI’s paper on external red teaming provides a detailed analysis of how the company strives to create specialized external teams that include cybersecurity and subject matter experts. The goal is to see if knowledgeable external teams can defeat models’ security perimeters and find gaps in their security, biases and controls that prompt-based testing couldn’t find. What makes OpenAI’s recent papers noteworthy is how well they define using human-in-the-middle
