Headlong Implements a Persistent Agent With an Infinite Bash Loop, Thinking and Acting Even When No One Is Asking

Laude Institute and MIT have open-sourced Headlong, a Bash-based system with fewer than 10,000 lines of code that treats messages as asynchronous observations within a continuous stream of thought rather than as new sessions. The design enables research into long-term memory and autonomous action, but it also turns token costs, permission isolation, and cross-user data boundaries into persistent risks.

Agent Lightning 1.0.1 Packages the Agent-Tuning Workflow as a Skill, Requiring Per-Run Measurement of Cost, Latency, and Accuracy

Microsoft has introduced an Agent Lightning Skill for Claude Code, Codex, and GitHub Copilot that lets a coding agent modify another editable agent against a fixed benchmark. It provides a budget-constrained set of experimentation rules; it does not automatically perform reinforcement learning on the target agent.

Ray 2.58 Completes KV-Cache/Token-Aware Routing, but the New Router Remains Alpha

Ray Serve LLM now centralizes prompt tokenization, cache-hit estimation, and replica selection at the ingress, then passes tokens directly to the inference engine. The design can reduce repeated prefill and tokenization, but no updated performance data has been published, and the control plane introduces additional synchronization overhead.

Anthropic Tests a Fine-Tuned “Lie Detector”: In-Domain AUROC Rises to 0.95, but Falls to Around 0.70 on a Different Type of Lie

The research team used eight open model families to generate roughly 200,000 examples of pressure-induced scenarios, then applied LoRA to train models to determine whether they themselves were lying. The detectors mainly learned surface-level patterns such as sycophancy and capability denial, performing only slightly better than prompting baselines on unseen lie types.

ReWorld Uses a Pose-Indexed Landmark Bank to Fix the KV Budget, Allowing Interactive World Models to Return to Earlier Scenes After Long Journeys

ReWorld assigns short-term action control and long-term scene memory to different attention ranges, then preserves history in a fixed-capacity landmark bank. The authors demonstrate real-time streaming at 704×1280 and 64-second return trajectories, but only the paper and demo page are currently available; neither model weights nor code have been released.

Prime Agent Open-Sources a Persistent RLM Harness That Keeps Agent Memory, Subagents, and Execution Environments Outside the Conversation

Prime Agent supports long-running coding agents with a persistent IPython environment, daemon sessions, and a versionable Continual Harness. Its authors report that ARC-AGI-3 RHAE Best@1 rose from 30% to 95.5%, but the score reflects the complete model-and-harness system and should not be treated as an isolated comparison of underlying model capabilities.

SWE-bench Science Releases 119 Scientific Code-Repair Tasks, With the Best Agent Still Below a 50% Full Pass Rate

The new benchmark uses private scientific tests to check units, numerical invariants, file semantics, and cross-module data flow, rather than merely whether code compiles. Claude Code paired with Opus 5 achieved an overall pass@1 of 47.90%, while experiments also showed that adding domain knowledge can sometimes anchor agents in the wrong direction.

DeepSeek Harness rc.2’s Split npm Tags: The Main Package Is Current, but Plugin Development May Pull in 0.0.x

The `latest` tag for DeepSeek Harness’s main package points to 0.1.1-rc.2, but several underlying packages still mark early versions as the latest. Installing the plugin API directly may trigger peer dependency conflicts or silently create a mismatched dependency tree.

GitHub Agentic Workflows Adds Real-Time PR Steering, but v0.87.4 Cited in the Official Weekly Report Does Not Include It

The new feature lets a running agent read PR comments and adjust its work based on `steer` instructions, while requiring explicit read permissions. However, the official weekly report recommends trying it with the earlier v0.87.4 release; deployments pinned to that tag will not actually get the feature.

NVIDIA Groq 3 LPX Enters Mass Production: Static Scheduling Delivers 3,431 Output Tokens per Second at 100K Context

Groq 3 LPX integrates 256 LP30 chips, 128GB of SRAM, and compiler-prescheduled inter-chip transfers into a low-latency decoding system. Third-party testing shows it leading existing public endpoints in long-context speed, but cost, concurrent throughput, and production-service performance remain undisclosed.

Slack Code Brings Coding Agents Into Temporary Collaboration Channels, but Initial Integrations and Permission Boundaries Remain Limited

Slack Code centralizes agent conversations, plans, code diffs, inline comments, and live HTML previews in project-specific channels. It inherits Slack’s channel governance and auditing capabilities, but repository permissions and real-world deployment side effects remain controlled by each agent integration.
