LastArray's research on reasoning trajectory modeling achieves 70.4 F1 on ProcessBench through step-by-step process evaluation, revealing critical gaps in stability and reliability that standard AI benchmarks completely miss.
We work at the intersection of data, systems, and human judgment, building learning systems that operate within real-world complexity.
Rather than isolated models or short-lived experiments, we focus on complete AI systems designed end to end, shaped by constraints, and built to endure.
Each solution is approached with care, accounting for data integrity, system reliability, human interaction, and the realities of long-term use.
We focus on building systems that behave well outside the lab. That means clear design, careful engineering, and an emphasis on reliability over appearance.
LastArray is a small, closely aligned team of researchers and engineers. We measure success by whether the systems we build continue to work as intended and earn trust as conditions change over time.
