A billion-scale mass spectral corpus arrives: 1.54 billion spectra across 35 species give de novo sequencing models a shared starting point

MassNet is an AI-ready mass spectrometry proteomics corpus of about 1.54 billion tandem mass spectra from 648 projects across 35 species, paired with a columnar tensor storage format called MSDT. Previously, mass spectra were scattered across heterogeneous formats such as MGF and mzML, with peak lists stored separately from peptide annotations and coverage skewed toward human samples. XuanjiNovo, a non-autoregressive model trained on this corpus, improves over state-of-the-art methods by 38.35% to 143.57% on human Astral data and also supports retention time prediction and PSM rescoring.

The two-to-six-week forecast gap gets a fix: probabilistic bias correction lifts AI and dynamical models alike, topping every variable in live competition

Subseasonal forecasts, two to six weeks ahead, have long hovered near the climatological average because errors compound, and operational dynamical ensembles and even state-of-the-art probabilistic AI routinely underperform climatology at longer subseasonal leads. Probabilistic bias correction uses machine learning to fix the forecast distribution itself rather than only a single point estimate. It doubles the subseasonal skill of an AI forecasting system and beats the operationally debiased dynamical model for 91% of pressure, 92% of temperature and 98% of precipitation targets; in the 2025 real-time competition its global forecasts ranked first for all variables and lead times.

Brain MRI foundation model drops the single-sequence habit: 1.55M scans, up to 15% few-shot gain on gliosis and MS

A New York University team released Neuro-JEPA, a multimodal foundation model that encodes T1w, T2w and FLAIR brain MRI contrasts in one architecture, pretrained on 1,551,862 scans from 428,647 studies. It outperformed BrainIAC, VoCo and NeuroVFM overall across 47 downstream tasks in three health systems and 12 public datasets while using less than one-third of NeuroVFM's pretraining data, and reached up to 15% higher few-shot AUROC on label-scarce tasks such as gliosis and multiple sclerosis, with roughly 15% on the NACC Alzheimer's disease task.

Meta ships an 816B open-weight multimodal model: 256 experts, 8 active per token, 1M-token context

Meta released Muse Spark Open, an open-weight model that puts text, images, audio and video into one mixture-of-experts model of roughly 816 billion total parameters and about 42 billion active per token, with a context window of up to one million tokens and text as output. It is trained for agentic coding, so it can read a codebase, write and debug code and call tools, while also taking a screenshot, a voice note or a screen recording as input. Compared with Muse Glimmer, the small dense model from the same series released in August, this scales the mixture-of-experts design up and ships BF16 and NVFP4 checkpoints with llama.cpp, vLLM and SGLang recipes.

Infrared vision without the costly camera: single-pixel feedback lets the projection grow into the target, visible at 0.11 photons per pixel

Infrared light is invisible to the eye, and conventional IR cameras rely on narrow-bandgap detector arrays plus cooling, making them costly and bulky. SIVIS sends IR and visible beams through one shared path, modulates both with a digital micromirror device, and uses the IR intensity read by a single-pixel single-photon detector as feedback so a genetic algorithm evolves the illumination pattern toward the target shape, while a matching visible pattern is projected onto the target or a screen. Static and moving targets are visualized in real time in both transmission and reflection, remaining discernible down to about 0.11 photons per pixel per detection (about 0.1 pW/cm²), with demonstrations in IR anti-counterfeiting and imaging through roughly 2 mm of biological tissue.

Agent safety in shared professional workspaces gets a comparison: a correct deliverable can still come with a secret written to a shared folder

APEX-Harm evaluates prompt and script injection against long-horizon agents on investment banking, law, and consulting tasks; across 12 frontier models Opus 5 and Sonnet 5 have the lowest overall attack success rates (8% and 20%), while task-specific script replacement and attacker-provided generic scripts still average 81–84% and 73%.

Most of the no-think RL gain in hybrid reasoning models is thinking leakage: erasing an 8-D think subspace at 8B removes 75% of it

Training Qwen3-1.7B, 4B and 8B with GRPO in no-think mode raises accuracy while responses grow longer, carry more reflection words, and internal activations shift toward the original model's think mode. Weight scaling, activation patching and attention-head interventions indicate that much of this gain comes from reactivating reasoning the original model already had rather than learning new reasoning behavior; at 8B, replacing an 8-dimensional think subspace removes 75% of the gain, and the reverse exchange transfers 50% of it to the original model.

For invisible inhaled objects, the AI stops giving a probability and points to a bronchial segment, lifting sensitivity from 18.8% to 56.3%

Radiolucent foreign body aspiration in adults sits at soft-tissue and mucus density on CT, so it has been found only by slice-by-slice manual reading and is easily missed. AI-PACS instead learns a standard Gaussian manifold of non-FBA airway topology from 804 unlabelled CT scans, flags deviations from that manifold as anomalies, and maps them onto the S1–S10 bronchial segments. In a 35-patient human-AI subset, sensitivity rose from 18.8% for radiologists to 56.3%, and average negative-exclusion screening time fell by about 75%.

vLLM runs an 816B sparse model on day one: 1M context at a quarter of the KV cache, over 960 tokens/sec on eight TPU v7 chips

vLLM shipped inference support for Muse Spark Open on release day, a mixture-of-experts model with 816B total parameters and 42B active per token, handling a 1M context window plus native image, video and audio input. Such models usually wait weeks for community ports; here Nvidia and AMD images arrived together with a trained DSpark speculative draft model. On TPU with speculative decoding, four v7 chips exceed 650 tokens/sec and eight exceed 960 tokens/sec.

Reasoning no longer blocks the action: masking current reasoning from the action expert keeps success and cuts latency up to 3.4x

Reasoning vision-language-action models previously made every action wait for autoregressive decoding of the reasoning text, which accounted for 53% to 70% of per-call latency. TacitVLA masks the action expert's attention to the current reasoning tokens, keeping only the training effect of reasoning supervision on the backbone representation, and on memory tasks generates each ledger entry during action execution. Across RoboMME, RMBench, LIBERO and PhysicalAI-AV it matches its explicit-reasoning counterpart while cutting latency up to 3.4x, and matches no-reasoning latency while improving success by up to 17.1%.

Local LLM inference is not private: an EM probe beside a Raspberry Pi recovers generated tokens and prompts

On a Raspberry Pi 5 running LLaMA-3.2-1B-Instruct locally, electromagnetic leakage captured by a passive probe can identify generated tokens and semantically reconstruct user prompts, showing that local execution alone does not keep prompts and outputs confidential.

Epidemic parameters without training a network: one least-squares solve, errors down up to four orders of magnitude

Parameter estimation for epidemic compartment models no longer needs neural-network training. Physics-informed regression previously estimated time derivatives from data, and that derivative estimate became the accuracy bottleneck when sampling was coarse or noise large, while point estimates carried no uncertainty. The new physics-informed weak regression integrates the model in time instead, keeps the equations linear in the parameters, estimates the unknown initial state jointly, and reaches fourth-order accuracy with cubic-spline quadrature; across the eleven DINN benchmarks it is the most accurate estimator in 15 of 22 model/noise settings, one to four orders of magnitude more accurate than the reported DINN results where sampling resolves the dynamics, at about a millisecond per fit.

Two-to-six-week forecasts stop being a coin flip: a postprocessing layer doubles accuracy and beats climatology for the first time

A machine-learning postprocessing layer that learns to correct errors in existing forecasting models doubles the accuracy of a gold-standard model over the two-to-six-week subseasonal range and, for the first time, consistently beats climatological averages.

Virtual atoms let electron density shape the interatomic potential encoder, not just a reconstructed field

Treating density query points as virtual atoms that share one encoder with real atoms lets electron-density supervision shape interatomic-potential representations: density error on MP falls below ChargE3Net, and joint training cuts zero-shot force error on larger molecules.

A wrist-worn single-lead ECG now flags 13 structural heart conditions, supervised by routine echo reports

A Peking University-led team aligned routine single-lead ECG with physician-authored echocardiography reports to train AnyECG-Echo, a screening framework that resolves 13 fine-grained structural heart disease subtypes at once. Earlier AI-ECG models mostly required 12-lead input, were validated within a single health system, or needed per-condition manual labels. Across internal, temporal and geographically independent external cohorts totaling 25,222 patients, the framework reached high AUROC for high-impact subtypes such as reduced left ventricular systolic function, global heart enlargement and mitral stenosis, and retained usable discrimination in the external cohort.

Semantic queries stop throwing away old labels: reusing past answers as views cuts model calls by 28% to 45%

Semantic query engines pay a large language model for every tuple they filter, and SemViews turns labels that earlier queries already paid for into semantic views that order tuples, certifying the answer only with fresh samples, meeting precision and recall targets while saving 28% to 45% of model calls on four workloads.

Judges agree more, humans no closer: rewriting only contested rubric clauses lifts panel consensus

A label-free procedure turns disagreement among LLM judges into rubric repairs, rewriting only the most contested clauses; on SummEval it raised inter-judge agreement by 0.069 while agreement with expert ratings showed no detectable change.

A million asteroids no longer lean on soft constraints: symplectic graph neural ODEs cut position error to 1.8×10⁻⁴ AU

For large asteroid swarms whose orbits must be reconstructed across observation gaps, a graph neural ODE was built with symplectic structure inside the network: instead of approximating conservation laws with soft penalty terms, a Hamiltonian generates the equations of motion directly, and planetary sphere-of-influence radii modulate message passing between bodies. On a one-million-body simulation spanning the Main Belt, Jupiter Trojans, near-Earth asteroids and Centaurs, mean position error is 1.8005×10⁻⁴ AU with energy drift of 8.42×10⁻⁵; on NASA JPL Horizons ephemerides for 99942 Apophis, mean position error across a 60-day blackout is 1.7983×10⁻⁴ AU.

Meta opens an 816B coding-agent model: compressed MoE and hybrid attention cut long-session KV cache about 3.7x

Meta released the weights of Muse Spark Open, an 816B-parameter omnimodal mixture-of-experts model with 42.7B active at inference, co-trained with Muse Code for coding-agent workflows. A compressed MoE block and a hybrid global/local attention schedule cut inter-GPU traffic and long-session KV cache memory, and the model supports a 1M-token context with text, image, video, and audio input. On Meta-reported benchmarks it is competitive with frontier-lab models on agentic coding and knowledge work, though each model was tested with its own lab's coding agent rather than a shared harness.

Low-resource languages stop losing the expert pool: a category bias on routing, removable at inference

COAX adds a positive routing bias toward a designated expert subset for each data category during pretraining, letting languages, modalities, or domains with tiny data shares claim a larger expert share; across MoE models from 345M to 10.6B, low-resource categories lose less, while inference stays standard top-k routing.

A chest X-ray agent stops calling tools by default: it first asks whether evidence is needed, then blocks unusable measurements

The chest X-ray agent X-Ragent splits "should I seek evidence" from "is this measurement usable": the policy invokes region zoom, anatomical parsing and knowledge lookup only when needed, while quantitative measurements such as the cardiothoracic ratio enter reasoning only through an independent validity gate. Training runs in two stages, agentic supervised fine-tuning on 7,715 structured diagnostic trajectories followed by GRPO with an accuracy-gated reward that applies process terms only to correct trajectories. On the fully held-out ChestAgentBench, accuracy rises from 63.1% for the strongest baseline to 71.7%, with gains across all seven interpretation capabilities.

Conglomerate digital rock stops choosing: wide-field scans recover pore detail, permeability error falls to 18.56%

To resolve the field-of-view versus resolution trade-off in micro-CT imaging of conglomerate reservoirs, Hy-MambaIR chains windowed self-attention with a Mamba state-space model into a local-to-global reconstruction network that recovers high-resolution pore and gravel structure from low-resolution wide-field slices. On paired multi-resolution micro-CT data it reaches a peak signal-to-noise ratio of 33.36 dB, 1.31 dB above HAT, and hits 30 dB with 6.6-fold fewer training iterations; on an 855³-voxel representative volume the mean relative error of three-directional absolute permeability is 18.56%, falling to 3.59% after supervised fine-tuning on pebbly sandstone.

Sensors stop re-uploading similar scenes: on a hit, six bytes retrieve the stored image

Memento sends sensor observations by reference: the device searches a vector table in persistent memory for a similar past sample and, on a hit, transmits only an index, and modeling shows that on low-rate links such as LoRa a 25% hit rate cuts latency and energy by roughly a quarter.

Cross-day speech decoding without retraining the network: 65,792 input parameters lift all six T12 sessions

Across days, neural drift degrades a fixed intracortical speech decoder. One study confined adaptation to a 256×256 affine transform and bias at the neural input, updating 65,792 parameters, under 0.05% of the full model, while the recurrent encoder and phoneme classifier stayed frozen, using 40 or 80 labeled trials for supervised calibration. On the public T12 dataset, macro phoneme error rate fell 11.37% and 15.51% across six chronologically held-out sessions, with all six improving under all three seeds; on the independent T15 dataset the same frozen rule gave 2.72% and 10.05% reductions, with more session-to-session variability and neither budget below the nominal 0.05 reference threshold.

Pre-training scores stop tracking answer length: PriorBPB integrates a per-byte cost curve under one shared length prior, ranking tasks closer to accuracy

Bits-per-byte (BPB), a common pre-training score, divides a model's surprisal on the gold answer by that answer's UTF-8 byte length, yet part of the cost does not grow with answer length, so short-answer tasks and short items are penalized. Aleph Alpha's team fits each item's bits as a fixed overhead plus a per-byte rate, shows corpus BPB equals that fixed overhead divided by the task's mean gold length plus the per-byte rate, and releases PriorBPB in the open-source eval-framework: it integrates a per-byte cost curve against one length prior shared across tasks. Across five model families and more than 60 checkpoints, PriorBPB is far less correlated with mean gold length and tracks accuracy better than standard BPB.

A 24B reasoning model that activates only 2B parameters per token leads or matches on five of eight tool-use benchmarks

Liquid AI released LFM2.5-24B-A2B, a reasoning agent model with 24B total parameters but only 2B active per token, built to run locally on device. It keeps the predecessor LFM2-24B-A2B architecture while growing context from 32K to 131K tokens and vocabulary from 65K to 128K, and it now emits an explicit chain of thought before answering. Across 16 benchmarks it competes with Qwen3.6-35B-A3B, which has roughly 50% more total and active parameters: 48.09 versus 38.19 on LiveClaw and 27.69 versus 8.72 on AutomationBench, while decoding 184 tokens/s on an M5 Max.

Two-dimensional infrared spectra get an inverse solver: a multi-task network recovers transition-dipole matrices at 0.085 RMSE

Two-dimensional infrared spectroscopy has mostly supported classification or coarse parameter inference, while directly recovering the transition-dipole matrix remains a hard inverse problem. Spec2DipoleNet couples level-structure classification with dipole-matrix regression in one physics-constrained multi-task convolutional network, trained on 8000 simulated spectra generated by the non-Hermitian Hamiltonian method. On validation it reaches an RMSE of 0.085, an R-squared of 0.97 and a normalized cross-correlation of 0.98, recovering allowed transitions well while nominally forbidden transitions deviate more.

Coding agents' rule files stop being added by impression: four runs lift held-out pass rates from 22% to 77%

Cortex turns each developer correction into a replayable task and keeps a skill or rule only when repeated paired comparisons show a net gain and no task collapses; across four independent runs it raised pass rates on four project conventions from 21.5% to 76.5% on scenarios no session had played.

Sensor networks stop guessing only locally: nodes first find same-state neighbors, then recover the whole network

In heterogeneous sensing networks, agents previously could infer only their own state or rely on a central processor to aggregate measurements. A decentralized method called cluster-aware social learning now lets each agent use local observations and neighbor exchanges to identify connected groups sharing the same hidden state, maintain one belief per group, and map those beliefs back to individual agents, recovering the network-wide state configuration while exchanging only cluster-level information. Synthetic Gaussian experiments and real gas-sensor data both show beliefs concentrating on each cluster's true state once the cluster structure is frozen.

Single-cell multi-omics integration changes its starting point: factorizing cell similarities instead of rebuilding molecular measurements

Single-cell multi-omics integration must place cells into one representation when only some cells have both RNA and chromatin accessibility measured, a mosaic design. Mosaic Cell Relation Factorization (MCRF) skips rebuilding molecular measurements and instead computes similarities between cells, then factorizes those relations into cell factors plus a separate weight matrix per modality, with paired cells sharing one set of factors across RNA and ATAC. On scMultiSim simulations, MCRF had higher median NMI than UINMF in 22 of 36 original configurations and than MIDAS in 28, often with smaller variation across simulation replicates; on 102 newly generated larger datasets, UINMF and MIDAS had higher median ARI in all 24 configurations with four replicates.

TrialCalibre1 links a clinical question, study design, and executable analysis into one reviewable chain, covering reference-trial replication, direct target-trial emulation, and BenchExCal, which joins benchmarking, extension, and calibration. On synthetic PCORnet-style claims it used ASCET as benchmark and extended the clopidogrel-versus-aspirin comparison to ages 81–90: 6,069 benchmark and 1,602 extension patients, extension risk ratio 0.848 (95% CI 0.569–1.184), calibrated to a point estimate of 1.274 (0.439–3.700) with a sensitivity interval still spanning 1. Two reviewers rated 53/62 and 50/62 assessable SQL checks met and 12/13 R checks met, with protocol and proxy disagreements remaining.

Agent files stop dying with the sandbox: Vercel Drives hits general availability, so a new environment resumes the same repo

Vercel released Vercel Drives for Vercel Sandbox and made it generally available, keeping an agent's files separate from the execution environment that runs it. Previously an agent's workspace traveled with its sandbox, so changing environments meant preparing files again. A drive is created once and mounted at a path when a sandbox is created; everything under that path stays on the drive while the rest belongs to the sandbox, and a new sandbox mounting the same drive finds the repository and files the previous run left behind. Drives default to 1 TiB, 1 GiB on Hobby, up to 16 TiB, with read-only sharing and forks.

Runway video models move into private deployment: enterprises license weights and run generation and editing on single-tenant GPUs

Runway and Baseten are putting the Gen-4.5 and Aleph 2.0 video models into single-tenant enterprise environments. Previously enterprises could only reach these models through Runway Creative or the Runway Dev API, not run the weights inside their own isolated compute. Enterprises can license weights directly from Runway, run them on Baseten Dedicated Inference, and fine-tune on their own data; Baseten states a 99.99% uptime commitment for such dedicated deployments.

EEG attention decoding drops the fixed electrode graph: dynamic topology plus self-attention reaches 91.67% on three classes

EEG attention recognition has moved away from a fixed electrode-connectivity graph. Multi-band features were previously concatenated and channel relations were handled with a preset adjacency matrix, which struggles to capture task-dependent coupling. DGCSA treats electrodes as graph nodes, updates channel topology through a learnable adjacency matrix, and adds self-attention for global dependencies, while Bayesian-optimized band weights fuse power spectral density and differential entropy. On 873 three-second EEG segments from 20 participants, three-class accuracy reached 91.67%, above SVM, CNN and LSTM baselines; mean attention scores were also higher in VR than in 2D.

Coding agents stop reading files one by one: local index searches open-source repos first, cutting output tokens 2.7x

XERJ is a community-trusted local AI search that automatically indexes any folder, so a coding agent stops reading files one by one and pulls the exact code it needs. Its main use is reference coding: point an agent at a task, and it downloads the closest open-source repos, indexes them, and reuses how they solved the problem before writing its own code. In a controlled study this cut a coding agent's output tokens by 2.7x at the same 16/16 solve rate, with users reporting roughly 5x in everyday work; the gain is gated by memorisation, being neutral to harmful on popular public libraries the model already knows.

Skewed and heavy-tailed data can now pick an undirected graph: Student copula gives a zero-partial-correlation necessary condition

Student copula Markov networks express the pairwise Markov property as a necessary condition of zero partial correlation and pair it with a penalized ECM graph-selection algorithm, letting undirected graphical models be fitted to skewed or heavy-tailed data.

Voice agents no longer trade speed for accuracy: PhoneLLM Mini lands on Workers AI, following instructions and calling tools with thinking off

PhoneLLM Mini, a model from the Pipecat team at Daily, is now available on Cloudflare Workers AI for voice agents and other realtime AI applications. In a voice agent the language model sits between speech-to-text and text-to-speech, so every second it takes adds to the caller's wait; developers usually choose between a fast model without reasoning mode, which can miss instructions or tool calls, and a slower model in reasoning mode, which handles both well. Pipecat post-trained NVIDIA Nemotron 3 Nano 30B on phone and customer support scenarios so PhoneLLM follows instructions and calls tools better without reasoning mode.

An inference engine splits control from execution: C++ state machine owns the KV cache, Python stays for researchers

TokenSpeed is an open-source LLM inference engine for agentic workloads, backed by the non-profit LightSeek Foundation, aiming at TensorRT-LLM-level performance with vLLM-level usability in production agentic serving. It separates the scheduling control plane from the execution plane: the control plane is a C++ finite-state machine that uses the type system to enforce safe reuse of request lifecycles and KV cache state at compile time, while the execution plane stays in Python for fast iteration. Kernels are treated as a modular subsystem decoupled from the core engine through a portable public API, a centralized registry, and a plugin mechanism, and the project states it includes one of the fastest MLA implementations on Blackwell for agentic workloads.

Code Review leaves research preview: most reviews about 3x faster, from 20 minutes to 6-10

Anthropic has moved Code Review out of research preview into general availability for Claude Team and Enterprise organizations. Coding agents keep raising the pace of code writing while review remains the bottleneck; preview users said it caught real issues before a human reviewer saw the PR but wanted quieter, change-sized, faster reviews. General availability cuts most reviews from about 20 minutes to 6-10 minutes and lets admins pick Quick, Standard or Deep per repository.

Limestone thin sections get a lighter backbone: 2.095M parameters, 91.11% accuracy across six classes

Limestone thin-section classification now runs on a compressed MobileNetV3 backbone that folds texture enhancement and multi-level feature fusion into one lightweight network. Fine-grained carbonate grain boundaries and micritic matrix were previously attenuated by successive downsampling, while inter-class similarity stayed high and manual petrographic reading depended on expert judgment. On 3,600 images of six classes collected in Ordos, Xinjiang, Tibet and the Lesser Khingan Mountains, the method reaches 91.11% accuracy with macro precision, recall and F1 of 91.28%, 91.11% and 91.12%, at 2.095M parameters.

Fine-tuned models no longer need a second integration: OpenRouter private endpoints keep your team's deployments on the same model slug

OpenRouter launched Private Endpoints, letting enterprises register fine-tuned models, dedicated deployments, or reserved capacity as endpoints visible only inside their organization, while continuing to call them through the existing API, model slug, and routing preferences. Previously such deployments meant maintaining a second integration alongside OpenRouter; now an organization's traffic prefers the endpoint by default and can fall back to public providers under existing preferences when it is rate-limited or unavailable. Endpoints must be hosted by a BYOK-supported provider and serve a model already in the catalog, and activation requires one real request that verifies the key, streaming, usage reporting, and model ID.

Voice models stop waiting for your turn: GPT-Live-1.1 goes full-duplex as the default for Plus and above

The GPT-Live voice family has moved to GPT-Live-1.1 and GPT-Live-1.1 Quip, both keeping the full-duplex design that lets a model listen and respond continuously, follow pauses, interruptions and pace changes, and decide in the moment whether to answer or keep listening. GPT-Live-1.1 succeeds GPT-Live-1 as the default voice model for Plus and higher tier users, including Codex and Dots, while GPT-Live-1.1 Quip succeeds GPT-Live-1 mini as the default for others. Safety work follows largely the same path as the predecessors: training models to respond safely, measuring performance on voice-specific evaluations, reusing existing system-level safety integrations, and using the same monitoring, review and enforcement infrastructure.

Steel foundry defect analysis drops prompt rules for code gates, lifting defect-location mentions from zero to 16

Root-cause analysis of steel casting defects and equipment failures has moved its key checks out of prompts and into code. Previously a general-purpose model answered wrong and right with equal confidence, once calling temperatures above 1,300°C physically impossible and recommending a sensor replacement. The system constrains the model with deterministic decision gates, page-level documentation cards and verbatim citation checks, and on one casting raised mentions of the defect location from zero to 16, 11 and 3, while quantification density stayed far below the reference analysis.

Mastra adds trace imports: switch observability vendors without leaving call history behind

Mastra platform now supports trace imports, pulling existing traces from third-party observability providers into Mastra so they sit alongside Mastra-generated traces for debugging, filtering and comparison. Previously Mastra observability data could only be exported to third-party providers, so switching vendors often meant leaving trace history behind. Langfuse is supported first, with more providers to follow; imports preserve span types such as agent_run, model_generation and tool_call, along with parent-child structure, timestamps, inputs, outputs, usage and cost, while scores, feedback, datasets, attachments and logs are omitted.

AI agents talk too much and read too much: caveman 4.0 splits into six rocks and cuts 63 tokens to 20

caveman 4.0 turns a single output-shortening tool into six separately switchable parts that are all on after install, aiming to make AI agents say less, read less, and run on less. It leaves prompts alone because Adobe found that compressing prompts makes answers worse, and it leaves code and tool calls alone because JetBrains found agent sessions are mostly code and tool calls. On ten developer questions, with "Be concise" as the real baseline, /caveman cuts 3% more at the median and /ultracave 35% more, and 63 tokens become 20 for the same answer.

Decision models stop at right or wrong: d1-ultra trains calibration too, beating Jev 1.14 on accuracy and calibration across 112 evaluations

Liquid AI released d1-ultra, a multimodal decision model priced at $0.042 per million input tokens on the Liquid API. It targets harder, messier real-world cases such as spotting a defect on a circuit board against its spec or checking a damage claim against a customer photo, and answers three question types: noul, Choice, and Score. Compared with the previous d1 and Jev 1.14 across 112 unique evaluations, d1-ultra delivers higher accuracy and better-calibrated probabilities at the same price, and leads other decision models on the Artificial Analysis Decision Index by at least 8 points.

Repo rules stop depending on human review: Tessl Verifiers check every agent change for pass or fail

Tessl released Verifiers, which write a repository's coding rules as plain-text checks that an LLM judge scores as pass or fail on every code change, running like lint or tests locally, in pre-commit, or as a CI gate. Previously such rules surfaced only in code review or AI code review, which looks for general problems across a PR and will not reliably check the same rule on every run. Verifiers are in GA, default to the openai/gpt-6-luna judge, and can switch to the Jev model, which returns a verdict and confidence score per rule.
