Horowitz argues AI apps rely on proprietary data for defensibility
Ben Horowitz contends that AI applications are sophisticated systems, not simple wrappers, citing proprietary data as a key differentiator. He predicts long-term defensibility will come from customer retention rather than network effects.
Rao predicts post-Transformer architectures will drive efficiency gains
Naveen Rao argues that physical efficiency gains from Moore's Law have stalled, necessitating a shift to co-designed models and hardware. He forecasts a $10 trillion inference market within a decade, driven by reinforcement learning.
Anthropic IPO valuation softens to $1.5 trillion amid market freeze
Anthropic is preparing to file for an initial public offering with a target valuation of $1.5 trillion, down from earlier reports of $2 trillion. The reduction reflects a broader freeze in the equity market, where investors are currently paralyzed by valuation mismatches.
DeepSeek raises $15 billion despite US security restrictions
DeepSeek has raised approximately $15 billion, one of the largest funding rounds in China, two days after the US ordered federal agencies to remove its technology. The funding supports infrastructure expansion and open models for domestic and international markets.
