## In short

Nathan Lambert argues US policy could ban or delay any open-weights model above GPT 5.5 / Claude Opus 4.8 / GLM-5.2 within six months. He points to reported White House talks on an executive order for open models.

## What it is

In his July 12 Interconnects post, Nathan Lambert warns that open models face their sharpest regulatory test yet. He points to reported White House discussions about a new executive order to manage open models, which lacks official confirmation but he says could initially target Chinese-origin weights and government use.

## How it works

The prediction is concrete: within the next six months, US regulators are likely to ban or indefinitely delay any open-weights release meaningfully above the capability level of GPT 5.5, Claude Opus 4.8, or GLM-5.2. Lambert frames this as the moment the dominoes start to fall after months of trial-balloon policies.

## Why it matters

The essay pushes US labs to ship a competitive open model before the window closes, and argues the parallel 'distillation panic' is largely a regulatory-capture campaign. Lambert names Anthropic directly, criticizing the lab for building policy pressure with what he calls minimal technical evidence, while pointing out that Claude Mythos itself was jailbroken.
