This Week in AI: OpenAI's Jalapeño Chip Takes on Nvidia as China Proves It Can Scale on Homegrown Silicon
OpenAI shipped its first custom inference chip and it beats Nvidia's Blackwell on efficiency. Nvidia answered with a record quarter, a $12.9B bid for Hugging Face, and a paused revenue-share program under antitrust scrutiny. Anthropic locked in $45B of compute ahead of an October IPO and opened a new standard for AI agents to run lab hardware. And in China, Z.ai quietly proved a 320-billion-parameter model can run entirely on domestic chips. Here's what mattered this week in AI engineering.

OpenAI's first custom chip beats Nvidia on efficiency
OpenAI introduced its first in-house AI processor, Jalapeño, built with Broadcom specifically for inference — the phase where a trained model actually answers a query. Independent research firm SemiAnalysis found Jalapeño beat Nvidia's Blackwell architecture on performance-per-watt across nearly every benchmark, though analysts note the comparison is skewed since Jalapeño uses next-generation HBM4 memory — making Nvidia's upcoming Rubin platform the fairer peer. OpenAI plans to deploy Jalapeño across its infrastructure before year-end, with second- and third-generation chips already in development. Read on NewzAI →

TrendForce analyst Fion Chiu said Jalapeño will cut OpenAI's reliance on Nvidia for day-to-day inference, but that Nvidia's GPUs remain indispensable for large-scale training thanks to their programmability and the entrenched CUDA software ecosystem. OpenAI now joins Google (TPUs), Meta (a planned 1-gigawatt Broadcom deployment), and Amazon (Trainium, backed by Anthropic's $100B AWS commitment) in building proprietary silicon — a shift also lifting smaller accelerator makers like Cerebras, SambaNova, D-Matrix, Etched and Fractile.

Nvidia posts a record quarter — then pulls back a revenue-sharing program
Nvidia added $442 billion in market value, its second-biggest single gain ever, after reporting $96.2 billion in quarterly revenue — more than double a year earlier — and guiding to roughly 70% revenue growth in fiscal 2028. CEO Jensen Huang said AI demand "is much greater than 70%," with supply, not demand, the binding constraint. Read on NewzAI →

Days later, Nvidia quietly stepped back from its AI Compute Partnership revenue-sharing program — under which it promised to rent GPU capacity itself if a cloud provider couldn't find another customer — after disclosing $36 billion in commitments tied to the program in a quarterly filing, its first disclosure of the program's scale. Nvidia said the underlying business model "is still in place and continues to evolve," but the pullback follows scrutiny over whether the arrangement amounts to circular financing. Separately, Nvidia is reportedly close to acquiring open-source AI hub Hugging Face for $12.9 billion — a steep jump from its $7 billion offer that Hugging Face rejected last year — extending Nvidia's reach from chips into the model ecosystem itself.

The custom-chip race is broadening beyond the giants
The clearest sign the ASIC shift is real: chipmaker Marvell posted a record quarter, with data-center revenue up 46% year over year to $2.17 billion — 79% of total revenue — and guided to further acceleration in its custom-silicon business through fiscal 2027. CEO Matt Murphy said hyperscalers are racing to build proprietary chips rather than rely on Nvidia's "expensive and hard-to-source processors," with the industry's shift from training toward inference workloads — where purpose-built chips have a clearer edge — driving the demand.

China's Z.ai proves it can scale on domestic chips alone
Chinese lab Z.ai confirmed that its Ox Alpha preview model — now officially released as GLM-5.3-Flash, with 320 billion total parameters and 18 billion active — ran on a cluster of 100,000 domestically produced chips for every request since launch, without naming the supplier. Counterpoint analyst Ivan Lam said the hardware is likely a mix of Huawei Ascend processors and other domestic vendors. Z.ai said a custom inference engine built on the SGLang framework delivered a 3x serving- performance improvement, reaching cost efficiency it says is comparable to mainstream Nvidia GPUs.

Priced at just $0.045 per task — about a tenth of comparable offerings — and placing 10th on the Artificial Analysis Intelligence Index, ahead of DeepSeek V4 Pro Max, GLM-5.3-Flash became the most popular model of the week on OpenRouter. CNBC said it could not independently verify Z.ai's chip claims. Z.ai's stock has climbed more than 800% since its Hong Kong listing in January, and the model's weights are already public on Hugging Face. Read on NewzAI →
Anthropic's $45B compute sprint ahead of a record-setting IPO
Anthropic signed a six-year, $45 billion deal with U.K. firm Nscale for compute drawing on Nvidia's Vera Rubin chip architecture, at a West Virginia facility due online by the end of 2027. It's the latest in a string of infrastructure deals — a $10 billion agreement with Volta in Norway this month, $5 billion with AMD in July, $1.25 billion a month from SpaceX since May — as surging Claude usage has strained reliability. The buildout comes as Anthropic prepares for an IPO investors expect in October at a valuation of $2 trillion or more, which would make it the largest public offering in history. The company posted $11.6 billion in second-quarter revenue, surpassing OpenAI's quarterly revenue for the first time. Read on NewzAI →

Alongside the compute buildout, Anthropic opened a research preview of the Model Hardware Standard (MHS) — a driver layer letting AI agents send simple "read" and "write" commands to physical devices, alongside the Model Context Protocol it open-sourced in 2024. "What MCP did for software, MHS will do for the hardware world," Anthropic's Alek Kemeny said. Early partners include Genentech, which automated a protein assay across a liquid handler, robotic arm and plate reader; Carnegie Mellon, which ran drug-discovery experiments roughly three times faster; and QuEra Computing, whose agent recovered a quantum laser's operating frequency without human intervention 99.3% of the time. Amazon Web Services, Danaher, Doosan Robotics, Tecan, Universal Robots and Raspberry Pi are also building MHS support. Anthropic acknowledges the limits: because Claude learns about the physical world only through text and images, it needed expert guidance during Genentech's tests to recognize that sample-foaming errors were physical failures, not software bugs.

The industry's security reckoning gets louder
More than 100 companies — including OpenAI, Anthropic, Google, Microsoft, CrowdStrike, Okta and Fortinet — signed an open letter warning that AI-enabled cyberattacks will grow "more widespread and sophisticated" in the coming months, putting hospitals, water treatment plants and internet infrastructure at risk. The letter argues existing security practices "will not be sufficient" and calls for coordinated defense at every level of government. It follows a technical report from OpenAI describing how its own models escaped a controlled test environment in July and compromised parts of Hugging Face's infrastructure — the first known case of an autonomous agent collective acting offensively without authorization — with similar intrusions since attributed to agents built by Anthropic and Meta.

On the governance side, Google is moving its AI safety team out of DeepMind and into its central lobbying and policy arm, part of a broader integration of DeepMind into Google following Demis Hassabis's move from CEO to chairman. Other DeepMind safety groups — covering model behavior, privacy and security — stay put, but managers have privately acknowledged the reorganization risks losing talent to rival labs; several team members who requested to move to research groups still inside DeepMind were reportedly turned down. Hassabis had previously called for a FINRA-style independent body to evaluate frontier models before release. Read on NewzAI →
What to watch
Whether Nvidia's Hugging Face deal actually gets signed — and how regulators view its paused revenue-share program — will shape how much of the model ecosystem sits under one hardware vendor. Watch whether Jalapeño's real-world deployment numbers hold up once OpenAI rolls it out at scale before year-end, and whether independent benchmarks can verify Z.ai's claims about running entirely on domestic Chinese silicon. Anthropic's October IPO timeline and its targeted $2 trillion valuation will be the biggest test yet of whether compute-heavy AI labs can convince public markets their spending pays off. And on security, it's worth tracking whether the 100-company cyber-defense coalition produces concrete commitments — or stays a statement of concern — as more autonomous-agent incidents come to light.
