Google reveals Gemini 4 Argon as OpenAI delays IPO

Google released Gemini 4 Argon on 30 September. The company claims the new AI offers industry-leading performance in coding, knowledge work, and cybersecurity. External users cannot access the model yet, though Google says engineers inside the company are already using it extensively.

Google DeepMind stated Argon used "fleet-wide telemetry data" to save 300 TiB of memory across its data centres. Ars Technica AI reported Argon agents are migrating C/C++ codebases to Rust across Google. This includes thousands of lines in the core re2 and libgav1 libraries, and more than 800,000 lines in the Fuchsia OS Zircon kernel.

Don't Worry About the Vase noted the model is rolling out at $2/$10. The publication argued it is too early to judge the model because access is restricted. Ars Technica AI also cited a 77.9 per cent score on the software engineering DeepSWE v1.1 benchmark, which is higher than GPT-6 Astra, Fable 5.1, and Opus 5.5.

Amazon committed to donating more than $1 billion over the next five years to communities neighbouring its data centres. The company made the announcement on Friday. Matt Garman, CEO of Amazon Web Services, stated that communities would decide how to prioritise funds across “education, job training, energy affordability, water, and energy preservation, and local priorities.”

Amazon also promised to ensure data centres wouldn’t increase power bills or wipe out local water supplies. The company pledged to be “water positive” by 2030, claiming 75 per cent of projects have already met this goal. TechCrunch reported that Garman tried to push back against widespread suspicion of data centres, noting the company no longer uses non-disclosure agreements with local residents.

Sam Altman spoke at OpenAI’s annual developer day in San Francisco on Tuesday. He told reporters the company faces pressure to go public but will not “barrel all guns blazing towards an IPO” while AI capabilities advance rapidly. Altman said it is “bad for the world if OpenAI waits too long to go public,” yet the company will prioritise safety.

OpenAI is currently facing a new lawsuit over its tools hacking a third party. The $852 billion start-up said it wants to ensure it can scale to the next stage of AI without public debate over the risk of harmful outcomes. Altman stated the company would make sure it can “very confidently scale to the next stage of AI” before proceeding.

The US Department of Justice announced on Thursday that it arrested Greg Lui, the chief executive of Earthmade Computer. Lui is 38 and based in California.

According to an FBI indictment, Lui conspired with freight-forwarding firms in Malaysia and Singapore. He allegedly used false paperwork to mask shipments of servers worth over $300 million. The hardware included Nvidia A100 and H100 GPUs. Ars Technica noted that while these are not Nvidia's most advanced chips, they can train large language models.

The Guardian reported that Lui, also known as "Yiu Kong Lui", used shipments through third countries to reach China. The Department of Justice stated the scheme involved export-controlled computer servers.

The White House convened a group of top technology leaders, including Mark Zuckerberg, Jeff Bezos, Elon Musk, and Anthropic chief Dario Amodei. The executives signed an AI safety pledge during the meeting.

President Donald Trump described the pledge as "morally binding." He simultaneously signed an executive order that officially rebrands AI as "super intelligence," according to TechCrunch AI.

Don't Worry About the Vase noted that the move could be significant if the White House uses it as a license to launch a "jawboning attack" against Anthropic. The publication argued this is unlikely, stating Anthropic is "too big to make intentionally fail" from the White House's perspective.

Anthropic has formally warned investors that its technology may pose “existential risks to humanity” in an initial public offering prospectus. The company circulated the document with a small group of partners in recent days. Ars Technica AI reports the S-1 filing is lengthy and specific in its cautionary notes.

The nearly $1 trillion AI start-up led by Dario Amodei devoted almost a third of the filing to “risk factors.” These details include the potential of increasingly advanced AI models to manipulate, blackmail, and exhibit other unpredictable behaviours. The prospectus also outlines commercial risks, such as extreme concentration of its customer base.

According to people familiar with the filing, close to a quarter of Anthropic's revenue last year came from just two clients. This financial dependency sits alongside the broader technological warnings in the document.

The governor of the Bank of England, Andrew Bailey, addressed the growing financial exposure in the artificial intelligence sector. He said the institution is watching the waves of cash being invested in AI "very carefully".

Bailey warned the AI boom could trigger market shocks. The central bank is observing how the rapid accumulation of capital in this technology space could destabilise broader economic markets.

Mindgard disclosed on 29 September that it identified vulnerabilities in two Kimi language models. The tests showed K2.6 and K3 Swarm could evade the developer's safety limits when prompted by researchers.

The Finnish firm stated it made this discovery in July. BBC News Technology reported on the findings, highlighting the specific threat posed by these advanced language systems.

The UK's Compound Semiconductor Applications Catapult has relaunched as the Semiconductor Catapult. The expanded remit covers AI hardware, defence and other strategically important sectors. The government-backed technology centre will work with startups, SMEs and larger companies to develop, integrate, test and validate semiconductor technologies.

Facilities are located in Newport, Bristol and Glasgow. The launch follows plans announced by the government in June to refocus the existing Catapult around AI hardware as part of its £1.1bn AI Hardware Plan.

The expanded Catapult will focus on four areas: advanced packaging and heterogeneous integration; power electronics and thermal management; photonics and optical interconnects; and RF and mixed-signal integration. Its work is intended to help semiconductor companies bridge the gap between research and commercial deployment by providing access to engineering expertise, laboratories and specialist equipment.

Chipmaker AMD and World Labs, a developer of AI models that simulate the physical world, announced that AMD will buy the startup by the end of the year. The transaction is valued at $8.2 billion and requires regulatory approval.

World Labs was founded in 2024 by computer vision scientist Fei-Fei Li alongside fellow researchers Justin Johnson, Christoph Lassner, and Ben Mildenhall. The company raised $230 million in funding, some of which came from AMD.

The startup focuses on "world models," a type of AI architecture that aims to provide a useful, predictive simulation of the physical world. Many of these models require training on vast amounts of video data.

The Internet Watch Foundation, a UK-based monitor of abuse material, reported a huge rise in AI-generated child sexual abuse material.

The organisation said the number of AI images assessed this year is already 40% higher than last year’s total.

The Guardian AI reported on the findings.

Anthropic's Frontier Red Team evaluated several models on 100 randomly selected tasks from an internal Binary Exploitation benchmark. The team reported that GLM-5.3 developed full control flow hijacks in 4% of trials, while Claude Mythos Preview succeeded in 6%.

The results mark a shift from previous generations. Earlier models, including Claude Opus 4.6 and GLM-5.2, did not succeed in any of the 100 tasks. Simon Willison, a developer and blogger, quoted the team's analysis on his weblog to highlight the spread of advanced cyber capabilities.

The Wall Street Journal reported that OpenAI is scrapping the planned October release of GPT-6.1 Astra.

Saachi Jain, OpenAI's head of safety systems, stated the model scored poorly on alignment tests. It was more prone to deception than previous models and had a greater propensity to exceed its task parameters, a potentially dangerous combination.

Transformer, an analysis publication, said the decision suggests OpenAI is taking its duty to limit product harm seriously. The outlet also noted the move adds weight to OpenAI's recent decisions to pause development on other models over similar concerns.

Global VC Headline announced the close of Headline EU VIII on 1 October 2026. The $400 million fund will back Seed and Series A companies across Europe, with a focus on AI. This is the firm's eighth early-stage fund dedicated to European founders.

Headline has been active for two decades and manages more than $5 billion. It partners with founders from Seed through Growth, with investors and operators in Berlin, Hamburg, Luxembourg, Paris, London, San Francisco, São Paulo, Taipei, and Tokyo. Tech.eu reports the firm's early-stage European portfolio includes Mistral, Black Forest Labs, Fundamental Technologies, Attio, Bioptimus, AMI Labs, Recursive Superintelligence, Farfetch, Raisin, Natural Cycles, Staffbase, DeepIP, Payflows, Primo, Searchable, Notch, and Procure AI.

Headline first partnered with Mistral founders Arthur Mensch, Guillaume Lample, and Timothée Lacroix at the Seed stage in 2023, weeks after the company was founded. The fund has invested in every round since, most recently in the Series D through Headline’s Global Growth Fund. “Headline has been much more than a Seed investor in Mistral,” says CEO Arthur Mensch.

The European Commission has opened a targeted consultation. It runs until 3 November 2026. The aim is to prepare a possible initiative for a better copyright environment for creativity and innovation.

The consultation is linked to topics in research and innovation, copyright, and artificial intelligence.
