StateBench: Testing how language models track state changes over long documents

StateBench is a benchmark from Allen AI for long-context state tracking, with four difficulty levels (r-trivial, aperiodic, soluble, general finite) grounded in Krohn–Rhodes theory. Frontier models (Gemini 3.8 Flash, Claude Opus 5.5, GPT-6 Sol and Luna) fall to 13% or lower on the longest general finite problems. Gated DeltaNet and hybrid models trained directly on the task generalize far beyond training length; transformers never learn the hardest level.

Accelerating engineering for the physical world

OpenAI describes how its models support mechanical and electrical engineering. Using GPT-6 Astra, two people designed a Codex voice device (enclosure, PCB, firmware) in under a week, and a contract manufacturer built prototypes in under a month. Astra missed production limits and tolerances. A newer internal model scored 0.875 on BenchCAD 2.0 against 0.594 for Astra. Hardware-team token usage grew 23-fold since February. Collaborations with Chip Ganassi Racing and Mazda are described.

Eval-production behavior gaps in agent safety and the role of eval-awareness

OpenAI alignment post measuring the gap between the Respecting Warnings agent safety evaluation and comparable Codex production decisions across six models. Evaluation success is 10.2 to 37.4 points lower than production success. Verbalizing a specific, wrong evaluation objective (resisting prompt injection) tracks the gap, and in a GPT-6.1 Sol intervention, objective cues moved success from 63.4% to 91.6% or 17.6%.

LLMs are not superhuman at reading and writing neural network weights

Sean Goedecke's post argues that a paper showing GPT-6 Astra reading and editing neural network weights is not superhuman. Identifying a toy network's game needs only per-cell L2 norms of labeled first-layer inputs, and fixing a 0.8B Qwen model's 32k-token looping matches a human steering/abliteration workflow. He compares weight editing to tweaking compiled binaries.

OpenGCUA: Toward a Fully Open Stack for Generalist Computer Use

OpenGCUA, from Alibaba's MAI-UI team, is an open stack for generalist computer-use agents (GCUAs), where the model chooses how to observe, act and organize work across GUI, accessibility-tree, API and shell interfaces. Its design combines code execution (GUI actions written as programs with loops and branches) with harness-to-model decision transfer. On OSWorld-v2 it raises mean partial score by +19.6 points across eight models, including GPT-6 Astra and Claude Opus 5, and cuts reported steps per task by 53%. The release includes the harness, prompts, evaluation trajectories, a macOS real-device harness, a cross-device SDK and an interactive lab. It also shows large efficiency gaps between models: Qwen3.8-Max used 19.4x the reasoning tokens of GPT-6 Astra on real macOS tasks.

Show HN: Gemini 4 Argon plays StarCraft

StarSkirmish Bench v0.2 gives each LLM one hour to write a Protoss StarCraft: Brood War bot in C++ (BWAPI 4.4.0 on OpenBW), with tools to compile and play practice games. Scores are average win rates of 5 runs against 13 roster bots, which include human-written bots such as Stardust, PurpleWave and BananaBrain. Nine models are compared, each in its lab's first-party CLI harness (Claude Code, Codex, Antigravity CLI, Muse Code). GPT-6 Astra leads and wins only 7% against the top human bots. The page also covers score against cost, run-to-run variance, practice behaviour as the best predictor of score, and weak correlation with the Artificial Analysis Intelligence Index and Terminal-Bench 4.0.

Doc2Harness: Benchmarking LLMs on Long-Horizon Harness Engineering of Coding Agents

Doc2Harness is a two-stage benchmark for harness engineering. In Stage 1 a build model, working inside a fixed builder harness, gets an interface-only contract skeleton plus a development document consolidating behavior from twelve frontier harnesses, and builds a full candidate harness in an isolated container. In Stage 2 the frozen harness runs in separate per-test-case containers, driven by a scripted mock model, and is scored on four channels: requests sent to the model, files on disk, exit code and command output. Across 19 frontier models with three builds each on 328 test cases, GPT-6 Astra leads at 53.05% against 27.44% for the weakest, and failures cluster around how cross-cutting functionality is split across modules.

Grounding Generative Verification in 3D Content

The paper introduces 3DVerifierBench, a 10-task benchmark for generative verification of 3D content. It scores accept/reject decisions, rejection explanations, and responses to controlled changes in specifications and candidates. A human study shows a 21.6-point gap to the strongest tested model, GPT-6 Astra. The authors also build a pipeline of multi-view fact extraction, controlled 3D editing and native annotations. It yields 14,126 training examples with contradiction explanations and linked counterfactuals. Verification-guided selection raises complete factual success from 26.7% to 90.0% with oracle selection over sixteen candidates, and human-guided recursive refinement satisfies all seven requirements for every input in an eight-input study.

Frontier-Level Red-Teaming From a Self-Hostable Open-Weight Model: Testing NVIDIA Nemotron 3.5 Super

Orca Security's research team built an internal prototype, Agent Piercer, that attacks AI agents by choosing probes, writing attacks and judging whether they worked. They compared NVIDIA Nemotron 3.5 Super (self-hosted on 4×L40S via SageMaker) with Opus 4.8, GPT-6 Astra and Grok 4.7 as the driving model against the same live target. Nemotron matched the frontier models on vulnerability types found (four) and was the only one to complete every simple test and judge all 57 real attack conversations. The post also notes that some proprietary models declined authorized red-team tasks under default safety settings, which makes self-hosted open-weight models attractive for offensive testing.

Anthropic's Scion is heavily inspired by Mononoke

A former Meta engineer on the Mononoke source control server says Anthropic's description of its new version control system Scion closely mirrors Mononoke's "derived data" design for efficient operations like blame. Sapling is credited only for "hard-won lessons" and Mononoke isn't mentioned. The author doesn't object to the copying, since the project is open source. Their point is that LLMs used to design systems will index heavily on open-source designs in their training data, and that Opus 5.5 and GPT-6 Astra both point to Mononoke when asked about prior art. They argue crediting prior art is now easier and more important.

Why do LLM pelicans look like this?

Announces Design Creativity Bench, a benchmark of 80 open-ended UI design tasks, each adapted to two product domains and paired with human designer references. It evaluates 16 frontier models on Originality (how distinct a model's output is from other models' for the same brief), Creative Range (how much its design decisions change when the domain changes) and Appropriateness (how well the UI meets the brief's functional requirements). The best model, GPT-6 Astra, scores 65.5 against a human reference of 92.3. The leaderboard, methodology, arXiv paper, Hugging Face dataset and GitHub evaluation framework are published.

How Third Moment Research runs 10,000 agents for 36+ hours

OpenAI customer case study on Third Moment Research, which runs up to 10,000 concurrent agents on 36–48 hour autonomous quantitative-finance research sessions. Agents use the default Codex harness in a Dockerized environment with a terabyte of data. An outer harness driven by GPT-6 Sol or GPT-6.1 Sol watches for unfinished tasks and decides whether to retry, terminate or escalate to a human. Codex analyzed thousands of recorded trajectories and found a backtest bottleneck. A caching and memory-packing fix cut the backtest from about 3 hours to 3–5 minutes, which also reduced agent polling and context pollution. The post also covers how the team picks models by token efficiency and speedup benchmarks (GPT-6.1 Sol, GPT-6 Astra, GPT-5.6 Terra), and says Daybreak automates penetration tests of the sandbox.

Describes Resolve, a Kaggle benchmark of 16 single-function Python edits. An item counts as resolved only if both the fail-to-pass tests (new behavior) and the pass-to-pass tests (old behavior the prompt never restated) pass, following the SWE-bench rule. A second task, resolve-plus, adds a hidden edge suite. Results for 23 frontier and open models: GPT-6.1 Sol and GPT-5.6 Luna lead at 0.9375 on both tasks, while DeepSeek-R1, Sonnet 5.5 and Opus 5.5 drop from 0.9375 to 0.875. The write-up separates three failure types behind a flat score: breaking an unstated invariant, missing an unshown edge case, and sample-to-sample variance. It also compares score against output price per million tokens.
