https://cognaptus.com/blog/2026-09-10-when-worse-inputs-score-better-audit-the-credibility-behind-the-benchmark/ Thu, 10 Sep 2026 00:00:00 +0000 https://cognaptus.com/blog/2026-09-10-when-worse-inputs-score-better-audit-the-credibility-behind-the-benchmark/ A router-worker audit shows why benchmark accuracy needs a second dimension: confidence that the score reflects generalization rather than sensitivity to benchmark-related cues. https://cognaptus.com/blog/2026-09-07-reasoning-under-a-running-clock-why-agent-rankings-reverse-in-real-time/ Mon, 07 Sep 2026 00:00:00 +0000 https://cognaptus.com/blog/2026-09-07-reasoning-under-a-running-clock-why-agent-rankings-reverse-in-real-time/ STAR shows why model selection for time-sensitive agents

https://cognaptus.com/blog/2026-08-06-the-leaderboard-is-not-a-clinical-clearance/ ClinMM-Bench shows why healthcare teams must test diagnostic models by specialty, reasoning quality, and failure mode—not leaderboard rank alone. https://cognaptus.com/blog/2026-07-31-stocked-but-not-synthesizable-ursa-tests-the-chemistry-inside-the-route/ Fri, 31 Jul 2026 00:00:00 +0000 https://cognaptus.com/blog/2026-07-31-stocked-but-not-synthesizable-ursa-tests-the-chemistry-inside-the-route/ URSA shows why route completion is a weak procurement metric and offers a staged way to screen retrosynthesis systems before chemists commit laboratory effort. https://cognaptus.com/blog/2026-07-24-agree-once-remember-later-the-commit-boundary-in-personal-agents/ Fri, 24 Jul 2026 00:00:00 +0000 https://cognaptus.com/blog/2026-07-24-agree-once-remember-later-the-commit-boundary-in-personal-agents/ A benchmark of stateful personal agents shows that the largest sycophancy risk emerges when user claims are written into durable state and reused later. https://cognaptus.com/blog/2026-07-02-the-room-remembers-the-model-forgets/ Thu, 02 Jul 2026 00:00:00 +0000 https://cognaptus.com/blog/2026-07-02-the-room-remembers-the-model-forgets/ LongSpace shows why long-video AI needs spatial memory, not just larger context windows.

when the manual is available: retrieval, policy reasoning, tool discovery, and state-changing execution break in different places. https://cognaptus.com/blog/2026-03-02-dare-to-benchmark-why-data-science-agents-still-trip-over-their-own-pipelines/ Mon, 02 Mar 2026 00:00:00 +0000 https://cognaptus.com/blog/2026-03-02-dare-to-benchmark-why-data-science-agents-still-trip-over-their-own-pipelines/ DARE-bench shows why AI data-science agents need verifiable workflow discipline,
