Sparse Attention under Long-Context Load

Keiko Nakamura, Rafael Alvarez, Dela Orsei

Long-context models are increasingly deployed in real-world applications where documents can span thousands of tokens. Our results show that performance depends on attention allocation across long contexts.

3.2 Sparse Attention under Long-Context Load

We evaluate sparse attention across three benchmark datasets with varying context lengths.

The quality of an early decision depends on more than the business itself. We look at the founder, skills, resources, constraints, ambitions, market, and surrounding context so the direction actually fits the person responsible for carrying it forward.

Early-stage founders rarely suffer from a lack of options. The harder problem is deciding which path has the strongest justification. We research, challenge assumptions, weigh tradeoffs, and form a clear position on what we believe should happen next and why.

At the beginning, attention, time, money, and energy are unusually scarce. We help determine which problems deserve those resources now, which can wait, and which should be ignored entirely before unnecessary work begins to compound.

A recommendation is most valuable when it can survive contact with reality. As customers respond, assumptions change, and new problems emerge, you can revisit the original thinking, test new information against it, and bring important decisions back to Seedcore when deeper judgment is needed.
