An open letter to Dario: if you mean it, open the weights! Jacob Gold published an open letter on jacob.gold calling on Anthropic CEO Dario Amodei to back a law requiring any AI model offered to the public to be released as open weights, following Amodei's "We Must Pace the Frontier" post that committed Anthropic to embedded third-party evaluators and urged governments to require rival frontier labs to match. Gold argues every regulation Amodei has sought — embedded evaluators, compute thresholds, and industry coordination with antitrust waivers — ends in regulatory capture that protects incumbent labs, and cites Anthropic's $1.5 billion settlement with authors and its Public Benefit Corporation status as evidence Amodei could make the sacrifice. Sam Altman agreed with Amodei's pacing proposal within hours, according to Politico. An open letter to Dario: if you mean it, open the weights Dear Dario, You published We Must Pace the Frontier https://darioamodei.com/post/we-must-pace-the-frontier today, which committed Anthropic to embedded third-party evaluators and asked governments to require every other frontier company to match. Sam Altman agreed within hours. 1 fn:1 I believe you’re being sincere, so I’m asking you to call for a different law, one that would actually slow things down, even though it would require real sacrifice on your part. Any AI model a company offers to the public has to be released as open weights. This wouldn’t cover every model you train, just the ones you make available to the public. Internal and research models wouldn’t be affected, and governments could still get access to unreleased models. But Anthropic would have to publish Fable’s weights the day it was released, OpenAI would have to do the same with Astra, and so would everyone else. Every regulation you’ve asked for ends in capture every-regulation-youve-asked-for-ends-in-capture There’s no slowing down frontier models by regulation that wouldn’t lead to regulatory capture. Embedded evaluators, compute thresholds, industry coordination with antitrust waivers. All of it gets written with the help of the current frontier labs, because nobody else understands the technical details well enough to write it. Once it’s law, it only gets more complex, because every incident adds a rule and no rule ever gets removed. The big companies can afford the compliance teams and lawyers to keep up, and each new requirement makes it harder for anyone else to catch them. Instead of slowing you down, it protects your position and profits. Why I’m asking you why-im-asking-you You seem like a good and principled person, and you have a record of giving things up for what you believe. You left OpenAI to start a company with safety built in from the beginning, when the safe career move was to stay.
