Nvidia released Nemotron 3.5 Lightning, an open-source artificial intelligence model that the company says can run on a single graphics processing unit. The model is available for download, modification and use without charge or permission. Nvidia described it as lightweight and designed for autonomous agents, software that performs tasks in the background.

Jensen Huang, Nvidia’s chief executive, said in an interview with Axios that open-source AI benefits hardware sales. "Free AI should be great for hardware," he said. "Free AI should be great for chips." The release follows Huang’s first post on X, in which he argued that open models strengthen safety, accelerate innovation and enable sovereignty. He also published an open letter opposing restrictions on open-source AI development.

Nvidia said companies including CrowdStrike, CodeRabbit and Harvey have tested and customised the model. The company also introduced NeMo Switchyard, software that determines the most cost-effective AI model for a given task. Nemotron 3.5 Lightning is available through Hugging Face and Nvidia’s website.

Disagreement on the model’s size

The Decoder reported that Nemotron 3.5 Lightning has 3.6 billion parameters. Quartz reported that it has 30 billion parameters. The reports do not reconcile the difference.

What the coverage left out

None of the right-rated digests mentioned the companies that have tested and customised Nemotron 3.5 Lightning, including CrowdStrike, CodeRabbit and Harvey. None of the centre-rated digests except IBTimes and CNBC’s full reports quoted Huang’s open letter or his X post. The Decoder’s report of 3.6 billion parameters was not mentioned in any of the centre or right-rated digests.

How other outlets pictured it

Which photograph to run is each newsroom’s own choice. The leaning beside a name is that outlet’s published rating, not a claim that the pictures divide along it. Every picture is shown from the outlet’s own server and links to the article it ran in.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

1 rated outlet

  • CNBC’s report led on the model’s release as Nvidia’s first open-source offering since Huang entered the debate over open AI development. It quoted Huang’s statement to Axios that "Free AI should be great for hardware" and noted that the model can run on a single GPU. The report also mentioned the national security concerns raised by Kimi K3, a Chinese model that narrowed the performance gap with U.S. systems.
  • CNBC described the model as "lightweight" and said it is free for companies to download, use and modify. It quoted Huang’s X post: "Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty."

Centre

7 rated outlets

  • The six centre-rated digests led on different aspects of the story. IBTimes and CNBC’s full reports quoted Huang’s statement that open-source AI benefits hardware sales. The Information and Market Screener focused on Nvidia’s development of Nemotron 4, a larger model expected later in 2026. The Wall Street Journal’s digest said the model can help enterprises save on AI token costs.
  • Breaking The News and Quartz mentioned the model’s intended use for autonomous agents. Quartz was the only centre-rated outlet to report the model’s parameter count as 30 billion. None of the centre-rated digests quoted Huang’s X post or his open letter.

4 rated outlets

  • The four right-rated digests led on Nvidia’s development of Nemotron 4, the larger model expected later in 2026. Yonhap News Agency described Nvidia as an "open advocate" and noted its opposition to regulation of open-source AI. Globo and The News framed the release as part of a strategy to compete with Chinese models. Seeking Alpha mentioned both Nemotron 3.5 Lightning and Nemotron 4 in its headline.
  • None of the right-rated digests quoted Huang’s statement to Axios or his X post. None mentioned the model’s parameter count or its availability through Hugging Face.

Questions about this coverage

How did the left and right cover Nvidia open-sources Nemotron 3.5 Lightning, a lightweight AI model for…?
Of the 12 outlets on this story carrying a published leaning rating, 8% are rated left, 59% are rated centre, 33% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 24. The sections above set out what each side emphasised, in its own terms.
Is Nvidia open-sources Nemotron 3.5 Lightning, a lightweight AI model for… left or right?
Neither side dominates it. Of the 12 rated outlets on this story, 8% are rated left, 59% are rated centre, 33% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Nvidia open-sources Nemotron 3.5 Lightning, a lightweight AI model for… biased?
Nvidia open-sources Nemotron 3.5 Lightning, a lightweight AI model for single GPUs is one event reported by 24 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Nvidia open-sources Nemotron 3.5 Lightning, a lightweight AI model for…?
24 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
What is Nemotron 3.5 Lightning?
Nemotron 3.5 Lightning is an open-source AI model released by Nvidia that runs on a single GPU. It is designed for autonomous agents and can be downloaded, modified and used without charge. Reports disagree on whether it has 3.6 billion or 30 billion parameters.
Why did Nvidia release an open-source AI model?
Nvidia CEO Jensen Huang said open-source AI increases demand for the company’s hardware. He called it "great for chips" and argued that open models strengthen safety, accelerate innovation and enable sovereignty. The release follows his public opposition to restrictions on open-source AI development.
Which outlets reported different parameter counts for Nemotron 3.5 Lightning?
The Decoder reported that Nemotron 3.5 Lightning has 3.6 billion parameters. Quartz reported that it has 30 billion parameters. The reports do not reconcile the difference, and no other outlet in the sample mentioned either figure.
What is Nvidia developing next?
Nvidia is developing Nemotron 4, a larger open-source AI model expected later in 2026. The Information and Market Screener reported that the company aims to compete with the world’s leading open-source models.
