Sources: OpenAI and Anthropic quietly lobby Washington regulators to restrict open-source AI models, even as Sam Altman publicly says he supports open source AI

This is rank anti-competitive maneuvering.

New York Times 2026-07-27

Context & Ripple Effects

The reported Washington push extends OpenAI's earlier effort to frame certain foreign models as privacy and security risks in its call for restrictions on PRC-produced models. It also follows collaboration among OpenAI, Anthropic and Google through the Frontier Model Forum on detecting alleged adversarial distillation.

Together, those developments show leading closed-model labs increasingly engaging with policy and enforcement questions around who may build, access and reuse advanced models. The contrast between the reported lobbying and Altman's public posture makes model openness a credibility and competition issue as well as a safety one.

First-order effects

OpenAI and Anthropic place restrictions on open-source models before Washington regulators as a live policy option, rather than leaving model access to voluntary company policies.
Open-source model developers and their users face a more directly contested regulatory environment, while the two labs risk scrutiny over the gap between public messaging and private advocacy.

Second-order effects

Rival labs, open-source developers and enterprise users have an incentive to argue that any restrictions should be narrowly tied to demonstrable risks, rather than rules that favor incumbent closed-model providers.
The policy debate may increasingly merge safety, security and competitive concerns—an approach foreshadowed by the labs' information-sharing on model distillation attempts.

Third-order effects

If regulators adopt access restrictions shaped by frontier labs, compliance capacity and government relationships could become more important determinants of which AI developers can compete.
The broader risk is that AI governance shifts from setting behavior-based safeguards to controlling model distribution itself, consolidating influence among firms positioned as trusted partners to the state.

The trend: This is part of the shift toward state-mediated AI governance, in which leading labs seek to shape the rules governing model access and reuse.

For my first post, I'm sharing a letter @NVIDIA signed on why open models matter. AI will transform every industry, power every company, and be built by every country. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. Th…

@satyanadella funny to see people jump to the conclusion I must want to ban open weight models.. I actually think open models can be very useful! But it's interesting how some historically extremely anti-open source companies are suddenly all in favor of openness 🤔
@davidsacks David Sacks on x
The entire tech industry (save for Anthropic) has come out in favor of open source AI. So what happens next? Will Anthropic change its lobbying efforts? Not likely. Now the gaslighting begins: “Nobody is trying to ban open source.” “We just want to limit who can use it.” “W…

I will say, it would have been easy for Anthropic to just sign the letter and then lobby behind the scenes and I respect that they didn't. They believe something and they're sticking to it even when costly.

Classic Bootleggers and Baptists! OpenAI and Anthropic want to do to Chinese open-source AI models what Detroit did to Chinese electric cars. https://www.nytimes.com/...

I think most people, when talking about open weights models, don't deeply believe in the vision of AGI/ASI that lab insiders believe in. Like they don't expect AI to really present grave semi-autonomous biosecurity or other similar risks. Whether it is right or not, no one knows,

@woke8yearold yep - there is no way to hold a consistent belief set where you're agi pilled and pro open source and this has been obvious since ilya wrote this 2015 or whatever. enormous cope ensues

Oh so innovation being driven by quasi monopoly returns accruing to companies run by their founders is bad now? I thought we had all read Zero to One?

this is the dumbest take i've seen all week, on par with ppl who say “if you care about homelessness then let them live in your house.” just an incredibly dumb purity test it's not too late to delete this my man

Anthropic is an ideologically captured organization seeking regulatory capture to protect both their business and their ideology. [image]

I'm so excited that @JensenHuang is a believer in open source now, looking forward to the CUDA and GPU driver open source release!

Yesterday they were signing open letters. Today they are yelling at people to “read the room. VCs have recreated BlueSky-politics from first principles.

Very happy to support this on behalf of Google. We have long benefited from open source, are big contributors to open source and in fact have consistently made open weights models with Gemma available from @GoogleDeepMind @demishassabis . Onwards!
@mikeisaac Rat King on x
the way this is playing out: the part of the industry that is conflicted on open source realizes it is better to all align against anthropic and box them out tons of frenemies against a common antagonist, and what better way to sway valley sentiment than say “hooray open source”
@thestalwart Joe Weisenthal on x
It's funny that this whole fracas kicked off because there was one eval which said that Kimi3 was near-frontier at frontend design work (probably one of the least important metrics tbh).
@davidsacks David Sacks on x
Nobody is saying that all software has to be open source. What they're saying is that open-weight AI should be allowed. By implication, they're rejecting your company's incessant machinations to kneecap the open model ecosystem. Read the room.

google spent the week fence sitting until this morning, now looks like they too want to be seen as pro open source now that everyone else signed the jensen letter

here's a story about the “open vs closed” debate over the past few weeks in the tech industry and how, depending on who you ask, the global economy and national security could be at stake w/ @kateconger @AnaSwanson and meaghan tobin https://www.nytimes.com/...
@bgurley Bill Gurley on x
Excited to see Anthropic acknowledge the real problem with open is it competes with their corporate economic strategy. The “awareness” here is revealing. When you build the biggest private market cap ever, you should expect competition. I'm sure the secondaries have been nice.

Open-weight models are essential to a healthy AI ecosystem. Together with others across our industry, we are outlining a path for open-weight models to strengthen American competitiveness and expand economic opportunity, while protecting national security. https://www.microsoft.c…

Open source is a positive and important force for both empowering people and preventing centralization. Proud to support this.

Anthropic and OpenAI are creating a Streisand Effect where their ongoing attacks on open Chinese AI models lets everyone know those models are actually so good that they're worth checking out.
@wowbaggert @wowbaggert on bluesky
These guys both know that their customers are going to migrate to cheaper self hosted open models the second they try to charge them the actual cost of their opex. — This is rank anti-competitive maneuvering.
