Iris Drives ML Experiments with a Revisable Knowledge State, Achieving a 64.9% Medal Rate on MLE-Bench in 12 Hours

Rather than repeatedly modifying code along a tree of candidate solutions, Iris first investigates critical unknowns and then organizes evidence across experiments into claims that can be added, updated, or retracted. The paper reports a higher medal rate on the full MLE-Bench in half the time allotted to its direct baseline, but the system’s source code and complete execution traces have not been released.

AtumAI Compiles Data Center Control Policies Into Searchable Specifications, Beating Human Baselines Across Three Task Categories

AtumAI converts natural-language requirements into an intermediate representation containing objectives, hard constraints, decision variables, and evaluation methods, then combines diffusion models, evolutionary algorithms, and surrogate models to search for policies. The study reports improvements in workload placement, resource scaling, and power management, but the results come from simulators and do not yet demonstrate that the system can safely take over a production control plane.

Harness-R1 Learns to Modify Execution Frameworks from Agent Failure Trajectories, Boosting Qwen3.5-9B Success Rate by 9.3 Points

Rather than adjusting the target agent’s model weights, Harness-R1 trains a separate 9B model to modify its context, tools, and validation code. The average success rate across three environments rose from 44.3% to 53.6%, but no public code is available yet to assess patch safety.

CMuon Splits Fused DiT Weights Before Orthogonalization, Training a 675M Model Twice as Fast as AdamW

CMuon finds that applying Muon orthogonalization to fused QKV, AdaLN, and FFN weights as a whole causes interference between functionally distinct subspaces. The study improves late-stage convergence through blockwise momentum orthogonalization, although the claimed 2× speedup has so far been validated only on a single 675M DiT configuration.

xPress Restores Causal Dependencies to Diffusion-Based Drafts, Boosting Qwen3-8B Decoding Throughput by About 1.3× on Average

xPress adds a single parallel causal refinement step between block-diffusion drafts and the target LLM, reducing early rejections caused by drafts in which individual tokens are plausible but the sequence as a whole is not. The study reports an average increase of about 30% in accepted draft length, but no public implementation is currently available for independent reproduction.

HALT Uses Evidence Coverage to Decide When RAG Agents Should Stop, Cutting Search Loops by Up to 45%

HALT no longer relies on a generative model’s confidence to determine whether a search is complete. Instead, it verifies each claim required to answer a multi-hop question against the available evidence. It can be added to frozen search agents, but the savings depend heavily on whether accurate intermediate claims can be generated in advance.

AgentTrajectorySentinel Uses Microsecond-Level Temporal Monitoring to Stop Agents From Going Off the Rails, Raising Task Success Rate From 52% to 73% in Tests

A new study replaces step-by-step review by a second LLM with trajectory-drift detection based on telemetry such as tool actions, latency, outputs, and token probabilities. The system costs about 200 microseconds per step, but each deployment must recalibrate it using its own normal trajectories.

PosterMELD Open-Sources an Editable Research Poster Agent Pipeline That Constrains Content Generation by Layout Capacity First

PosterMELD divides paper parsing, content compression, layout, and quality repair into a multi-agent workflow while preserving native PowerPoint elements in its output. The team reports an 81.3% print-ready rate, but its quality judge, API costs, and baseline configurations still require external validation.

Inflect v2 Updates Ultra-Compact Local TTS Toolkit, Letting Users Adapt Voices and Export a 4M-Parameter Model to ONNX

Inflect-Nano-v2 keeps the complete text-to-waveform model to 3.97M parameters, and a recent update adds a runnable single-speaker adaptation workflow. It is suited to offline and edge voice interfaces, but its training data, cross-lingual performance, and quality comparisons still lack independent verification.

MAI-Cyber-1-Flash Enters Preview, Handling 90% of Vulnerability Analysis with a Small Specialized Model

Microsoft’s MDASH is previewing its first in-house cybersecurity model, MAI-Cyber-1-Flash, handing off only the hardest tasks to GPT-5.4. Multi-model routing reduces scanning costs, but automatically generating exploits and patching production environments also increases risks around permissions and validation.

Copilot Automations Adds Comment Triggers, Allowing Users with Write Access to Launch Agents from Issues or PRs

GitHub Copilot cloud agent automations can now monitor Issue and Pull Request comments and launch tasks such as documentation updates and bug investigations when specified text appears. The feature shortens the path from discussion to agent execution, but private automation configurations, comment input, and available tools create new permission and prompt-injection boundaries.

GitHub Copilot Cloud Agent Adds Reasoning Effort Selection, Letting Complex Tasks Use More AI Credits for Deeper Analysis

GitHub now allows developers to specify both the model and reasoning effort when launching Copilot cloud agent tasks. Higher effort may improve cross-file debugging and architectural analysis, but it increases token usage and AI Credits consumption, requiring teams to establish new cost and quality benchmarks.
