YC CEO to Anthropic: Don't Ban Distillation, Open the Front Door

Anthropic wants regulators to crack down on what it calls "illegal distillation." Garry Tan, president of Y Combinator, has a blunt response: do nothing.

In September, Anthropic released its second threat intelligence report, accusing Chinese labs of hiding their identities and using stolen credentials to extract capabilities from cutting-edge models. CEO Dario Amodei had already called for U.S. regulators to step in. But in a CNBC interview, Tan took the opposite view. "I would do nothing," he said. "We can argue; there should be a U.S.-specific distillation mechanism."

Two Arguments: API Control Is Overstepping, and Authors Were Never Asked

Tan's position is simple: instead of banning distillation, let U.S. open-source labs distill from cutting-edge labs through the "front door" — openly and legally, through legitimate authorization, not stolen credentials.

His argument rests on two points. First, closed model labs controlling what users "can do with API outputs" is overstepping. In his words: "Controlling what users and customers can do with outputs from closed-source model APIs feels suffocating. The government has a role here — normalizing the idea that intelligence trained on widely available data should be a public good, not locked behind restrictive service terms."

Second, proprietary labs also used copyrighted materials during training without asking anyone's permission. The recent $1.5 billion copyright settlement Anthropic reached in July is a clear example.

The Real Driver: Fear of Monopoly

"The nightmare scenario for AI, the apocalyptic scenario, is when only one company remains," Tan said. "It has the best capital channels, the best AI researchers, and suddenly becomes a monopolistic giant." In his view, open-source weights are a counterbalance: "They are at the forefront and drive progress. We want this to be fundable, a good business. You also need to give people freedom and access through open-source weight models."

His statement carries weight because of the timing. Anthropic's threat report had just been released, and the U.S. government was considering action against AI distillation. YC, the biggest backer of the U.S. open-source startup ecosystem, saw Tan step forward and say "don't ban it" — effectively speaking for the entire open-source community.

The Unanswered Question

But Tan didn't address a sharp question: What if U.S. labs truly opened the "front door," and the distilled models were then sold or leaked? How to open that door, how wide, and whether there are walls behind it — Tan gave no answers. That's why "do nothing" sounds casual but is extremely vague in policy terms.

Key Points:

Anthropic accuses Chinese labs of "illegal distillation" and wants regulators to crack down.
YC's Garry Tan says: don't ban it; let open-source labs access capabilities legally through proper channels.
Tan argues API control is overstepping and proprietary labs also trained on copyrighted data without permission.
He fears a single-company AI monopoly and sees open-source weights as a counterbalance.
Tan left unanswered how to prevent distilled models from being sold or leaked.
