OpenAI and Anthropic Face Backlash Over Reported Lobbying Against Open-Source AI

According to the New York Times, OpenAI and Anthropic are quietly lobbying Washington regulators to restrict open-source AI models. This contradicts their public stance supporting open-source AI and has caused a massive uproar within the AI community. The core of the current debate has moved beyond technical parameters, evolving into a ideological battle over AI safety, regulatory capture, and commercial interests.

Confirmed

• Lobbying vs. Public Stance: OpenAI and Anthropic are reportedly lobbying against open-source models, despite Sam Altman's public claims of supporting open-source AI.
• Anthropic's Safety Warnings: Anthropic issued warnings reminding policymakers to prepare for severe safety incidents involving open-weight models in the future.
• Severe Backlash and PR Crisis: Multiple authors pointed out that Anthropic is suffering a reputation collapse. @firstadopter and @bgmshana noted that their stance invited public mockery, suggesting a smarter PR narrative would be "supporting open source, but opposing unfair distillation from China." @AIandDesign sarcastically noted the company's transition from a safety hero promising not to let AI be used for military killings to a "villain" suppressing open-source AI.

Unconfirmed

• True Motives Dispute: Relayed by @Signalman23, an alleged Anthropic employee stated the company opposes open-source not primarily for safety, but to protect its competitive advantage. @ctjlewis and @aiamblichus also argued that its ideals and commercial interests are heavily intertwined, as open-source directly threatens its business strategy. However, these remain accusations rather than conclusive internal facts.
• Whether Catastrophic Risks are Exclusive to Open Source: @davidmanheim and others questioned this notion, arguing that the risks of dangerous AI abuse are not limited to open-source, and that a monopoly on superintelligence by a few tech giants could be equally or even more dangerous.

Why it matters

This event marks an open schism within the AI industry regarding open-source. The open-source faction, represented by David Sacks, believes almost the entire tech industry has expressed support for open-source AI, with Anthropic being the sole exception. Voices against the ban argue that a blanket prohibition on open weights is "regulatory capture disguised as safety," which would harm the open research ecosystem. They advocate for regulatory thresholds based on model capabilities rather than open-source attributes. Meanwhile, voices like @bookwormengr argue that Anthropic genuinely puts its money where its mouth is regarding safety, earning respect even from those who disagree. This debate will profoundly influence the future trajectory of AI regulatory policies.
