It is a well studied phenomenon that any given model's reasoning ability degrades with the context length. If we can keep context tightly curated, we improve both accuracy and cost while making larger changes tractable in a single task. Dirac is an open-source coding agent built with this in mind. It reduces API costs by 64.8% on average while producing better and faster work. Using ...

AI should elevate your thinking, not replace it

TurboQuant: A first-principles walkthrough

A vector is an ordered list of numbers that can be thought of as an arrow in space, and its length and inner product can be calculated using the norm and dot product. The goal of TurboQuant is to store a vector using a fixed number of bits per coordinate while minimizing the mean squared error (MSE) of the reconstructed vector, and it achieves this by applying a random rotation to the vector ...

Three constraints before I build anything

To ensure creativity and focus, I use three constraints: a one pager that captures my north star, a core piece of technology that supports my product, and a defining constraint that gives my product identity. If a project fails to meet any of these constraints, I don't build it, as it will likely result in a complex, bloated, or unidentifiable product.
