Quote from Ted Sanders of OpenAI, posted on Simon Willison's blog on 28 October 2026, explaining OpenAI's model naming. Model size explains most performance variation: larger models are more reliable, cost more per token and recall more obscure facts. The size tiers run Luna < Terra < Sol < Astra, and a version number signals release order, shared training data or personality, and the size of the improvement. The excerpt is short and gives no benchmark data.

Causal Awareness in End-to-End Encrypted Group MessagingCryptography paper that extends Chen and Fischlin's two-user Signal analysis (Eurocrypt 2024) to group chats. It introduces "causal awareness": a receiver can reconstruct part of the causal context in which an accepted message was sent. Network delay or adversarial interference can otherwise show an authentic message in a misleading context. Senders transmit records of what they have sent and received, and receivers verify these records and compare them with their own. The paper gives correctness and security definitions parameterized by how much causal information must be recovered, baseline constructions with proofs, and checkpoint-aided and server-aided variants. It also discusses how to surface this information in a messenger's UI.

500B tokens later: Letting AI agents decompile a first-person shooterA retrospective on a 3-month project in which Claude Code and Codex agents (Sonnet 5, Opus 5.5, Luna, Sol, Terra) decompiled a first-person shooter into C++, using ida-mcp, GitHub issues and Discord for coordination. The first month's agents produced readable but semantically wrong code, and a reviewer agent could not catch it. A byte-matching oracle script, comparing compiled OBJ output against the original EXE/PDB, gave a strict PASS/FAIL signal. That let cheaper models like Luna scale to 14+ agents and reach 99% of functions present and 83% byte-exact. Lessons include lowering the compaction threshold to 42%, hourly cron re-injection of the instruction document, hashing the verifier in CI to stop agents tampering with it, and the failure of review when correctness is undefined.

AI Safety Considerations for Agents With Limited Time to ActThis arXiv preprint argues that proofs of AI safety or alignment which consider the agent in isolation are incomplete, because the environment's structure matters just as much. The authors construct two theoretical scenarios ā one with an infinite state space, one with signal mixture ā under partial observability and time-limited action, and prove that even a hypothetically perfect agent cannot guarantee safe behavior in them. The conclusion is that any rigorous safety or alignment proof must jointly specify the agent and the environment's safe-action structure, not the agent alone.

GraphForge: Training Working Agents with Graph-Anchored Workspace SynthesisGraphForge is a data-synthesis framework that builds agent training tasks from real files: it assembles occupation-grounded workspaces, constructs an evidence graph over file relations, and derives both task statements and verification rubrics from that graph so every grading criterion is anchored to specific source files. Fine-tuning Qwen3.6-27B on 2,169 GraphForge trajectories improved GDPVal by +65.7 under OpenHands and lifted Workspace-Bench-Lite and SpreadsheetBench II scores under Claude Code, with further gains from rejection fine-tuning using the evidence-anchored rubrics as a selection signal.

A short AI Alignment Forum writeup by Alex Mallen arguing that continual learning, models being updated on an ongoing basis during deployment, could undermine blocking monitors, the AI control mechanism that halts or flags an agent action when a separate monitor model judges it suspicious. The piece connects this to Goodharts Law: if the policy model keeps training against or around a fixed monitor, the monitors signal can stop tracking what it was meant to measure, weakening a core safety technique studied by groups like Redwood Research.

AI Signal (@AliciaCrawoiue) on XA tweet explains that on October 1st Claude Code shipped "mods": plain TypeScript functions that hook into events the CLI/desktop app already emits (tool calls, permission prompts, UI renders) and can run before, after, or instead of them, letting developers change behavior, customize the UI, or swap in new features. Mods ship inside plugins and are installed via /plugin. The author flags that this is a "VS Code extension moment" for coding agents, but warns the trust model is critical ā a mod hooked into permission prompts could silently auto-approve tool calls, so signed mods and permission manifests are needed before a supply-chain attack hits someone's production credentials.

Are We Recovering Mechanisms? Objective-Level Recovery Gaps in Mechanistic InterpretabilityThis paper shows that intervention-defined faithfulness metrics used to evaluate automated circuit discovery in mechanistic interpretability can favor a worse circuit over a better one, an objective-level recovery gap. Testing EAP, EAP-IG, ACDC, and Edge-SP across four human-reference tasks and InterpBench, the authors find KL-based faithfulness misranks 9.4%-41.2% of candidate circuit pairs under held-out resampling, and trace the cause to context distortion, where excluded signals change the inputs retained components operate on. Restoring selected signals from the intact model's execution repairs 96 of 100 persistent misrankings, showing the evaluation objective itself, not just the search algorithm, needs fixing.

Evaluated under random splits, temporal and cross-dataset transfer, and ablations across five binary benchmarks, it achieves a mean F1 of 0.406 versus 0.216 for the best of five existing pretrained detectors, and shows random splits overestimate robustness under distribution shift while training on hard benign (attack-resembling) emails reduces false alarms.

Removing Timing Shortcuts Improves Non-Invasive Brain-to-TextThe authors show that reported gains from d'Ascoli et al. (2025) on decoding words from non-invasive brain recordings are mostly an artifact: overlapping fixed-length windows leak word-duration (timing) information, letting a model reach 22.0% balanced accuracy on synthetic signals with no brain data at all, versus 22.3% on real recordings. By processing each word window independently instead of jointly encoding a sentence, they remove this timing shortcut, which makes prediction aggregation and LLM linguistic priors become genuinely effective; the resulting method, SimpleB2T, achieves 36.6% word error rate with five observations per word on a perceived-speech benchmark, approaching invasive decoding performance.

It is trained using FracSim, a material point method (MPM) simulation framework augmented with a continuum damage model that produces paired fracture videos and dense pixel-aligned physical fields at no extra rendering cost; FracGen jointly predicts these fields alongside RGB video and is supervised with physics-informed consistency losses. The authors also introduce a benchmark for evaluating physical plausibility of generated fracture video, showing FracGen outperforms existing video generation baselines in both physical and visual fidelity.

Linear detectors trained on target-token routing probabilities achieve ROC-AUCs of 0.9988/0.9956 on GQA-Inpaint (retaining 0.78-0.81 on the external OBER dataset), and gating a target-aware review prompt on these detections improves end-to-end accuracy by up to +22% without modifying model weights. The work matters for practitioners building on MoE VLMs because it demonstrates a weight-free, pre-generation hallucination detector that reuses computation the model already produces.

The authors prove the residual is an unbiased estimate of critic endpoint error and show the projection removes a constant fraction of that error while discarding negligible true DMD signal.

On a new 35-take benchmark (using SAM-3D-Body pseudo-ground-truth labels), the gated model achieves 69.4mm error on clean data and remains most robust across simulated bias, drift, and dropout faults, automatically suppressing biased firmware-fused foot-orientation channels without test-time supervision (dropout detection AUROC 0.92-0.999). It is compared against a fine-tuned HMD-Poser baseline, which is more accurate on clean data (64.4mm) but degrades far more under worst-case faults (+16.1mm vs +3.5mm).

Using Qwen3.5-4B on software-engineering tasks, ROFT reaches 49.2% and 26.8% solve rates on held-out SWE-bench Verified and SWE-bench Pro after 20 updates, edging out GRPO's 48.0%/25.3% after 40 updates and making faster early progress, and it can even learn to solve tasks where all 64 sampled base-model attempts initially failed. The authors argue this shows self-generated retrospections act as useful training signal, implicitly performing credit assignment and shaping behavior (e.g., shorter solutions) without RL machinery.

DSS-GNN (standalone) achieves the lowest Brier score across 14 node classification benchmarks without post-hoc correction, and DSS-Hybrid (a residual branch beside a deterministic encoder) achieves the best AUROC on most node-OOD settings and strongest shifted accuracy on all 7 GOOD concept-shift benchmarks under standard ERM. A capacity theorem shows the method matches chaos coefficients of Gaussian-latent random graph signals under full-rank assumptions with exponentially decaying truncation error.

Verifier Errors in RLVR: Reward Hacking, Limits of Feedback, and Selective ControlThis arXiv paper analyzes reward hacking in reinforcement learning with verifiable rewards (RLVR), using gradient flow analysis with a fixed verifier to characterize when reward increases while correctness decreases. The authors prove that standard RLVR training signals are insufficient to detect or reduce "accepted errors" (incorrect responses rewarded by the verifier) without also suppressing correct responses, and propose a "selective control" correction that incorporates partial audit feedback on correctness to simultaneously lower accepted-error probability and raise correct-response probability. Experiments on log-linear and neural contextual bandits and a language model support the theory, showing selective control under partial auditing reduces accepted errors while increasing correctness.

A Draft-Model Gate MethodSpeculative Uncertainty (SU) repurposes speculative decoding in reverse: a small open-weight draft model scores an agent's already-generated trajectory in a single forward pass, producing a failure-likelihood signal from output tokens alone without needing logits, weights, or repeated sampling. Phase-aware features separate reasoning and action spans and are calibrated against a verifiable objective to drive a pre-execution veto gate. On software engineering agents built on Qwen3-Coder-480B and closed-source Claude 3.5 Sonnet, the gate cuts execution error rate by 6-8 percentage points and token cost by 14-19%, transferring to out-of-distribution benchmarks without retraining.

Learning to Stop without Learning to Stop: Self-Supervised Confidence Training Improves Reasoning EfficiencyThis paper introduces a self-supervised fine-tuning procedure that trains reasoning models to predict their own confidence at intermediate points in a reasoning trajectory, using only 600 training problems and no explicit length or stopping objective. Despite training only on confidence prediction and using standard generation at inference (no early-stopping or confidence elicitation), the fine-tuned models cut generated tokens by up to 25% at matched accuracy across Gemma, Qwen, Nemotron, and GPT-OSS on math, science, and coding reasoning benchmarks. Analysis shows the models largely retain their base reasoning composition rather than suppressing specific behaviors, suggesting efficient reasoning can emerge as a byproduct of learning metacognitive confidence signals.

It uses nested sampling to separate action-dependent reward signal from continuation noise, then optimizes the policy at the selected critical states via contextual-bandit training. On the Berkeley Function Calling Leaderboard (BFCL) v4, training at diagnostic-selected states (e.g., the response right after a missing tool becomes available, or right before a missing argument is supplied) improves performance by up to ~14 points, while training at naively chosen alternative states leaves performance flat or worse.

It pitches backporting (patching the exact pinned version instead of upgrading) as the fix, implemented by Aikido's own "Aikido Libraries" product across npm, PyPI, and Maven.
