What comes after attention? This startup says it already knows.

When Subquadratic launched earlier this year, it could build a sparse-attention model that could handle a 12-million token context window The post What comes after attention? This startup says it already knows. appeared first on The New Stack .

Why this matters
Why now

Advances in AI model architectures are constantly pushing the boundaries of what's possible, with startups emerging to address limitations like context windows and computational efficiency.

Why it’s important

Breakthroughs in AI attention mechanisms can significantly enhance the capabilities of large language models, leading to more sophisticated and practical AI applications.

What changes

The ability to process much larger context windows in AI models via new architectures potentially reduces computational costs and increases AI model effectiveness for complex tasks.

Winners
  • · AI model developers
  • · Cloud providers with optimized AI infrastructure
  • · Enterprises leveraging advanced AI
Losers
  • · AI model architectures reliant on older attention mechanisms
  • · Providers of less efficient AI hardware
Second-order effects
Direct

New AI models will be able to process and understand significantly more information at once.

Second

This improved understanding could lead to more robust and accurate AI agents, accelerating their deployment across industries.

Third

Increased efficiency in AI training and inference could reduce the energy footprint of AI, potentially alleviating some 'energy-bottleneck' concerns in the long term.
