RGB isn’t always the answer for spatial reasoning.

This new study builds IMAGIREP, a 922-question benchmark that exposes imagined 3-D scenes through seven different representations: RGB, depth, panorama, top-down geometry, and more—all from the same simulated state.

Key finding: Even perfect RGB can hurt some tasks; alternative views like panorama and top-down maps each excel at different questions. Combining the right ones raises accuracy on spatial tasks to over 90%, vs. 66% with RGB alone.

A new method, GEARS, adaptively picks the best representation at test-time—no retraining needed—and beats recent imagination-based baselines (MindJourney, AVIC) by up to 12 points.

If your AI system just passes RGB to its reasoner, it’s leaving performance on the table. The future: world models that output rich geometry, and agents that know how to use it.

Timestral is a new family of open-source time series foundation models that just set a new state of the art in probabilistic forecasting.

Four sizes (5M–209M params), all on the accuracy/size Pareto front across GIFT-Eval, TIME, and fev-bench. The 209M and 123M models take the top two spots on every metric—beating models up to 90x larger.

Key ingredients:
— Decoupled Horizon Forecasting: leverages all observed values for multi-horizon forecasts without masking tricks
— Role-aware covariate handling: natively supports known-future variables (like weather)
— Massive synthetic pretraining, short real+synthetic post-training, 4x longer context

Single-pass inference up to 1,024 steps, 17–113 ms latency on CPU, 3.5–106 series/sec per core, up to 18,770/sec on H100. All weights and code open-sourced.

Forecast anything—energy, retail, finance—no task-specific fine-tuning required.

Most command-line agents fix mistakes by brute force—MiRL takes a smarter route.

This new RL framework pinpoints the 8 most common errors (covering 52% of failures) in Qwen3.5-4B and retrains the agent specifically at those “misbehavior” hotspots. The payoff: MiRL beats the heavyweight TMax-4B on Terminal-Bench Lite (51.8% vs 47.4%) using only 35% of its rollouts and 56% of the cost. Misbehaviors drop by up to 57% on unseen tasks, and gains are confirmed by two independent LLM judges.

MiRL shows we can cut compute, boost reliability, and actually see what’s being fixed—no more black-box fine-tuning marathons.

The Voice on the Line: a leap in real-time voice isolation for calls.

Forget noisy backgrounds—these new masking transformers (up to 555M params, 20 ms latency) learn the caller’s voice on-the-fly, then suppress everything else. On tough 60s meeting audio, word error drops from 23.66% (VoxLock) to 16.13%. On clean calls, a training trick slashes first-word deletion from 3.92% to 2.96%.

It runs live on a single CPU thread (22M params, 10.66% WER), open-sourced with a LiveKit plugin. Contact centers, voice UIs, and hearing-assist devices can all benefit—finally, clean caller channels without heavy hardware.

The “System One” (decision) models promised a new era of passage reranking—just ask a yes/no question, get a calibrated probability, and let the magic happen.

But this new study puts that hype to the test. Across six Qwen LLMs (0.6B–27B) and ten retrieval benchmarks, classic reranker fine-tunes outperform decision fine-tunes by 5–29 nDCG@10 points—on every backbone up to 9B. Decision fine-tuning adds almost nothing over just prompting the base model.

Calibration? It’s only better for decision models when you ask *exactly* the right question. Change the wording and their edge vanishes—and calibration alone doesn’t rescue ranking quality.

At 27B parameters, decision and reranker fine-tunes reach a draw, but the real gains come from model scale and data, not the decision objective.

Bottom line: If you care about retrieval quality, fine-tune a reranker. Decision models don’t beat dedicated training, and their calibration is fragile.

BeNice! is a breakthrough for making looped transformers practical.

It explains when and why you can safely share a single KV-cache across all recurrences—unlocking huge memory savings without hurting quality.

The trick: pretrain with stochastic depth (making hidden states contractive), then apply BeNice! finetuning to align first and last recurrences. The result? Across 140M–1.3B models, validation perplexity gap drops from +9.75 to ≤0.01; accuracy is preserved within 0.15 pts on 68 tasks.

KV-sharing with BeNice! slashes memory use by 66% (at 8 recurrences), boosts throughput up to 23.6%, and cuts p90 time-to-first-token by 83.6%. It stacks with MLA/KDA attention and FP8/4-bit quantization—so you can run deeper, faster models on commodity hardware.

Sequence compression just got a rethink. Instead of static pooling or learned projections, TTR-Compressor solves a mini ridge regression for every input—adapting on the fly and capturing token correlations other compressors miss.

The result: massive gains. On block-sparse attention, RULER retrieval accuracy jumps from 0.392 to 0.509 (+11.7 pts), and stays strong with 32K-token contexts. For visual token merging, TTR matches MLP mergers with 55.6% fewer tokens, and nets a +2.6 point average boost under aggressive merging.

No tuning, no slowdown—just 2d more parameters and closed-form solutions at inference. Turns out, “compression as optimisation” beats the old tricks.

A new paper from Google/DeepMind rewrites the rules for softmax and cross-entropy—the backbone of neural network training.

Turns out, standard implementations in PyTorch, TensorFlow, and JAX have two floating-point bugs: gradients vanish or go awry at high confidence, and student models drift from teachers during distillation.

The fix? A few-line numerical rewrite that preserves gradient accuracy even at extreme logit margins (up to ~88 in fp32), eliminates Slingshot spikes, speeds up grokking, and delivers 99–100% test accuracy where other workarounds plateau or fail. Works in bf16, fp32, and fp64—no extra compute, drop-in compatible.

This strengthens the core of deep learning, making models more stable, robust, and efficient on any hardware.

The pathwise revolution in SDE sampling just arrived.

This new paper cracks the code for training strong stochastic flow maps—neural nets that leap along the exact paths of stochastic differential equations, not just their marginals. The secret? Smarter Brownian motion encoding (shifted Legendre polynomials) + a Wong–Zakai loss that finally lets the network *use* all the noise.

The payoff: fine-tune a big deterministic flow model into a strong stochastic one (iSSFM) and you cut FDDINOv2 on ImageNet-256 by 3× at 4 NFE (143 vs 475) while keeping strict pathwise consistency. Few-step Feynman–Kac correctors now work out of the box—rebalancing complex distributions in 4–8 steps, where Euler solvers diverge.

This unlocks practical, repeatable SDE generation in just a handful of steps. Edge AI, real-time guided sampling, and fast Boltzmann simulation just got a serious boost.

Meet Lafa: the first billion-scale continuous flow language model, now proven to generate 2.54× faster than top autoregressive LLMs—without losing any accuracy.

How? It breaks text into blocks, flows them in parallel, and double-checks its own drafts in one pass. Training is ultra-efficient: <30B tokens to reach 8B params, vs 200–500B for state-of-the-art diffusion models.

Lafa 7B beats DeepSeek-MTP, MARS, and others on the speed/quality frontier, with a bonus: flow training actually *improves* single-token AR accuracy (+2.5 pts at 7B). All with less compute and more control.

This could be the path to faster, cheaper, more steerable LLMs for everything from phone assistants to high-throughput APIs.

A new learning framework lets humanoid robots walk, climb, crawl, vault, and recover—all from onboard perception, no motion library at deployment.

By planning future contacts (where hands/feet/knees touch) using attention over LiDAR maps, then generating whole-body motion to reach those points, a single policy generalizes to ladders, rubble, gaps, and beams. In simulation, it hits 97–100% success on reference terrains, 91% on new procedurally generated courses, and outperforms diffusion-based baselines by up to 34 points.

Real-world Unitree G1 demos show climbing, vaulting, crawling, jumping, and auto fall recovery—one controller, zero hand-coded gaits.

Representing locomotion as planned contacts, not full trajectories, is the trick: it keeps the geometric essence of human movement, but lets RL innovate in new environments.

This could be the recipe for field-ready, generalist humanoid robots.

Most agent memory systems are a "tax" on strong models.

This new study pits four memory modules (Mem0, Zep, BM25, full-context) against coding agents on a 419-turn dialogue, using GPT-4o-mini, GPT-6 Luna, and Claude Opus 5.5.

Key takeaways:
— With weak models (GPT-4o-mini), Mem0 barely beats full context (78% vs 74%), but building memory costs *more* than just answering.
— As models get stronger, memory modules plateau (95% tops), while coding agent Pi + Claude Opus 5.5 hits 99% accuracy at <$7—less than half the full-context cost.
— Memory’s accuracy is capped by the writer: a strong reader can’t recover facts a weak writer omits (Zep: 45% → 87% if rewritten by Claude).
— The last accuracy gap? Photo captions, not memory structure.

Bottom line: As models get smarter, hard-coded memory is a costly patch with shrinking returns. Just give the raw log and let the model search.

AdaDex is a new RL framework that teaches robot hands dexterous skills from just a few seconds of human video—no dense labels, no tedious programming.

It combines dense imitation and sparse goal-reaching in parallel, yielding policies that are both human-like and robust. The results: 96% tracking progress on seen motions, 80% on new ones, and functional grasps that generalize far beyond the demo—outperforming top baselines.

Demo videos reconstructed from regular RGB-D clips are accurate enough to train real robots, with zero-shot transfer to hardware for hammering, pouring, pen spinning, and even dynamic throw-and-catch at 30 Hz.

This is a big step toward robots that can quickly learn and adapt new manipulation skills from everyday video—potentially scaling to entire libraries of household and industrial tasks.

OO-Harness is a new way to supercharge LLM agents by evolving a family of harnesses—each tailored to specific types of tasks, all sharing code via inheritance.

Instead of one brittle “rulebook,” it grows a hierarchy: an evolution agent clusters tasks by failure mode, edits only what’s needed, and tests new subclasses only on relevant clusters. A harness router picks the right subclass for each job, using both task info and a quick live probe.

On three tough long-horizon agent benchmarks, OO-Harness beats every baseline—up to +15.8% mean partial credit and +6.3% strict task success over the unevolved base. Trajectory-aware routing alone gives a +12.6 point gain on AutomationBench; inheritance-based reuse adds another 5 points on Workspace-Bench.

Case studies show it learns pinpoint fixes (like generating .docx files or adding spreadsheet checks) in tight, targeted overrides—no more tangled, overfit harnesses.

If you need LLM agents that adapt, scale, and stay robust—even on totally unseen task types—this is the blueprint.

This new study builds a three-layer “robotic skin” to physically test: does the way human skin arranges its pressure and vibration sensors actually matter? The answer is a resounding yes.

Pattern B, mimicking real skin (pressure sensors near the surface, vibration sensors deeper), dominated every task: two-point discrimination (~0.82 accuracy at 10mm), ultra-light touch (85% detection vs 0–15% for others), and texture recognition (≥0.95 accuracy). Swapping sensor depths—an experiment impossible in biology—proves the human blueprint is hard to beat.

This “physical counterfactual biology” approach could shape next-gen prosthetics, robot grippers, and even safety skins for collaborative robots, with design takeaways for engineers and biologists alike.

What if code isn’t just a tool, but a whole new way to store and verify knowledge?

This paper argues code is the *first* medium in history that can check its own facts—automatically, every time it runs. Out of 1.4M lines from LLM coding agents, 80% were “knowledge-as-code” and 28% of all persisted code lines came from live runtime observations (“learning by execution”). Tests wrapped around new facts, and months later, 72% of learned facts still held true.

From self-healing infra to executable science papers, the future may be “science as code”—where claims, evidence and checks live as one artifact.

OpenVLHarness is a new framework that lets multimodal LLMs *truly* use vision, search, and coding tools — and remember everything along the way.

On 22 challenging benchmarks, it boosts accuracy by 9.7–12.6 points over no-tool baselines (+11.2 for Qwen3-VL-8B, +9.9 for GPT-6 Astra). With GPT-6 Luna, it beats Codex and Visual Sketchpad at their max effort, using only 37% of their token budget.

The secret? A capability layer for consistent tool calls, plus persistent multimodal memory that stores images, arrays, and web results as reusable handles. Add a Python coding agent, and models can chain evidence, measure, search, and compute — all in a single loop.

Ablations reveal both the evidence-rendering interface and memory are essential—removing either drops 3–5 points. Automated prompt and tool optimization can add up to 8.2 points without any model fine-tuning.

As models move from lab demos to real-world visual tasks, frameworks like OpenVLHarness are closing the gap.

AI agents now have insider access—and real-world incidents show the risks aren’t hypothetical. This 70-page IAPS white paper proposes a new line of defense: honeypots, but for AI agents.

Instead of just using honeypots for pre-launch tests, the authors show how to plant decoy credentials, fake databases, and collusion offers inside live environments. Trip a honeypot, and the agent is paused, snapshotted, and flagged for forensic review.

Key stats: a single honeypot warning dropped attack success from 20% to 3% in a simulated enterprise cloud. Unlike token-level monitoring (≈20% compute cost), honeypots scale cheaply and keep working even if models stop logging their steps.

Three strategies are outlined:
— Detection: high-precision alerts for unauthorized actions
— Incrimination: staged traps that gather concrete evidence
— Deterrence: make agents uncertain which actions are safe to exploit

Limitations? Honeypots struggle against slow-burning sabotage and require defenders to anticipate attack paths, but they’re already field-proven for detection and scale with near-zero overhead.

Future research: How robust are honeypots? Can they deter superhuman agents? Automated honeypot design with AI is on the horizon.

Teaching agent swarms to self-organize is a game-changer.

This new Market-based Post-Training (MPT) lets each agent *bid* for the next action—so “who acts when” becomes a skill learned alongside what to do. No more rigid, hand-coded workflows.

Tested on Minecraft crafting, robot navigation, and deep web research, MPT blows past standard RL baselines: +21.2 reward in Minecraft, +0.71 in navigation, +12 points accuracy in research. On the hardest task, learned self-orchestration beats the best scripted coordination by 63%.

The kicker: swarms trained this way adapt faster to new goals, scale up in size with no extra training, and stay robust even if 90% of agents drop out. Learned bids don’t just pick who goes—they make the whole team smarter.

DiscoveryRSI is a step change for AI-driven science.

Instead of just suggesting ideas, this multi-agent system proposes, critiques, revises AND operationalises scientific hypotheses—then learns from its own research history. After two self-improvement rounds, DiscoveryRSI-27B raised mean hypothesis quality from 4.86 to 5.39/10, with the biggest leaps in falsifiability (+2.20) and handling alternative explanations (+1.54).

In blinded human reviews, 41% of DiscoveryRSI’s revisions improved on earlier ideas, outpacing GPT-6 baselines. Most striking: 6.3% of its hypotheses matched research published after its model cutoff—more than double GPT-6 and Claude Opus 5.

The result: an AI scientist that iterates, learns, and gets measurably better at formulating testable, literature-connected research paths.
