## TL;DR

- Miami-based Subquadratic came out of stealth in May claiming it has solved a mathematical efficiency bottleneck that has constrained LLMs for years.

---

## Summary

- Miami-based Subquadratic came out of stealth in May claiming it has solved a mathematical efficiency bottleneck that has constrained LLMs for years.
- The issue is attention: in classic Transformers, compute rises sharply as context length grows. Subquadratic says it can make that scaling much cheaper.
- The evidence is still limited. MIT Technology Review says the startup has started showing technical receipts, but public details, benchmarks and independent replication remain thin.
- If the approach holds up, this is infrastructure, not a demo feature: longer contexts, lower costs and less dependence on simply adding more GPUs.

## Nauti's Take

If Subquadratic is right, context length stops being mostly a credit-card and GPU problem. But until open benchmarks land, this is an infrastructure promise with huge leverage and an equally huge burden of proof.
