Anthropic Weighs Rushing New Model to Counter OpenAI's Astra, Forcing Conflict With CEO's AI Slowdown Call

On September 21, 2026, reports emerged that Anthropic is internally debating the accelerated release of a new frontier artificial intelligence model, just seven days after its CEO published a 3,800-word essay urging the industry to slow down.[3]

The internal discussions center on how to counter the rapid enterprise adoption of OpenAI's GPT-6 Astra, which launched on September 3.[2]

According to data from corporate expense platform Ramp, Astra captured roughly 13% of tracked enterprise AI spending within weeks of its release, overtaking Anthropic's Claude Fable, which sits at about 8%.[1][2]

This shift in market share marks the first time in over two and a half years that OpenAI has led Anthropic in developer spending on routing platforms like OpenRouter.[1][2]

The commercial pressure arrives at a sensitive moment for Anthropic, which is preparing for an initial public offering.[3][4]

Anthropic's annualized revenue run rate exceeded $65 billion by the end of July, up from about $9 billion at the end of 2025, while OpenAI's run rate passed $40 billion in the same month.[1]

With Anthropic projecting 2028 revenue of roughly $190 billion to $200 billion, prospective investors are scrutinizing whether OpenAI's latest release could permanently displace Anthropic's long-held status as the leader in enterprise AI tools.[1][3]

The potential model launch creates a stark public contrast with Anthropic's recent safety messaging. On September 12, CEO Dario Amodei published a manifesto warning that unchecked capability gains could allow rogue AI agents to cause widespread damage.[2][4]

Amodei's essay, which drew public agreement from OpenAI CEO Sam Altman and SpaceX CEO Elon Musk, argued for a deliberate, industry-wide slowdown and enhanced safety evaluations. "We must slow the pace at which we improve the capabilities of AI models," Amodei wrote.[1][2]

Now, Anthropic is reportedly evaluating the safety profile of its unannounced model while simultaneously weighing the financial necessity of defending its market position.[2][4]

The tension highlights a broader industry dynamic: while leading labs publicly agree on the need for coordinated safety frameworks, the financial realities of high interest rates and multi-billion-dollar revenue targets continue to drive rapid deployment.[2][3]

As Anthropic finalizes its IPO timeline—potentially pushing the listing until after the November US midterm elections—the decision on whether to ship the new model will test whether commercial imperatives or safety philosophies ultimately govern the frontier.[1][3]
