Chinese AI startup Moonshot AI has released its Kimi K3 model, a 2.8-trillion-parameter system that costs 80% less than Anthropic's Fable 5. The launch has drawn a sharp warning from former White House AI advisor David Sacks, who said the US is falling behind in the global AI race.
A model that dwarfs competitors
Kimi K3's 2.8 trillion parameters make it one of the largest publicly known AI models. Moonshot AI priced the system at a fraction of what Anthropic charges for its Fable 5 model, which has not disclosed its parameter count but is widely considered a top-tier offering. The 80% price gap is a direct challenge to US AI companies that have dominated the high-end market.
Sacks' warning: 'We're losing the race'
David Sacks, a prominent tech investor and former PayPal executive who served as White House AI advisor during the Trump administration, said the US is losing the AI race following Kimi K3's launch. He did not provide specific policy recommendations but pointed to the rapid progress from Chinese firms as a sign that American leadership is slipping. Sacks has been a vocal critic of what he sees as insufficient US investment in AI infrastructure and talent.
What the price gap means
The 80% cost advantage could reshape the AI market. Enterprises that previously could not afford top-tier models may now turn to Kimi K3, especially for tasks that require massive scale. Moonshot AI has not disclosed the hardware or training costs behind the model, but the pricing suggests significant efficiency gains. Anthropic has not responded to the pricing comparison.
The next move
US AI companies face pressure to either match the price or justify their premiums with superior performance. Policymakers in Washington are watching closely. The Biden administration has already issued an executive order on AI safety, but Sacks' warning adds urgency to calls for more aggressive federal support. No official US response to Kimi K3 has been announced.
