GPT-Red introduces an automated red-teaming agent trained via scalable self-play to discover prompt injection attacks against frontier models. It was used to adversarially train GPT-5.6, representing a massive safety training run.

We introduce GPT-Red, an automated red-teaming agent that is trained to discover novel prompt injection attacks against frontier LLMs. The goal of this model is to evaluate and improve the robustness of our production systems. To this end, we use it to adversarially train GPT-5.6, our most robust model to prompt injections to date. To create GPT-Red, we design a scalable self-play algorithm where the model is tasked with attacking a diverse population of simultaneously-trained defender agents. W

This study introduces shadow evaluations, assessing frontier AI agents on unpublished NeurIPS research papers graded by the original authors. It offers a rigorous alternative to blind peer review for measuring progress toward automated AI research.

Forecasts of explosive AI progress hinge on AI agents automating AI research. But evidence on whether agents can carry out open-ended AI research is thin. Current evaluations either test agents on narrow, verifiable tasks, which excludes open-ended research, or submit AI-generated papers to blind peer review, which is overstretched, stochastic, and suffers from poor review quality. We introduce a third way to measure progress towards AI R\&D automation. An agent takes on the central, open-ended

AI Analysis

MindForge automates the conversion of open-source programs into source-free training environments covering the entire software engineering life cycle. This provides scalable training data for writing complete programs from scratch.

Coding agents have made substantial progress on software engineering tasks that modify existing codebases, including bug fixing and feature implementation. However, constructing a complete program from scratch remains a major challenge: even the frontier models evaluated on ProgramBench fully resolve fewer than 1% of tasks. One obstacle is the lack of scalable training environments for this from-scratch setting, spanning the whole software engineering life cycle, as existing environment-construc

The Ambient Capture Engine (ACE) transforms real homes into synchronized recording studios capturing first-person perception, motion, manipulation, and sound. It serves as a comprehensive embodied data engine across table and room scales.

Embodied intelligence faces a fundamental data bottleneck. Models must capture how first-person perception, whole-body motion, dexterous manipulation, object state, sound, and touch evolve together as humans pursue goals over time. Existing datasets fragment this experience across viewpoints, modalities, or spatial scales, leaving the full perception-action loop only partially observed.

TurboVLA: Real-Time Vision-Language-Action Model at 32 Hz on an RTX 4090 with <1 GB VRAM

AI Analysis

TurboVLA introduces a direct vision-language-to-action mapping paradigm that bypasses LLM-centric bottlenecks, achieving real-time 32 Hz performance on consumer hardware. This approach significantly reduces computational and memory overhead for robotic policies.

Vision-language-action (VLA) models commonly adopt an LLM-centric V to L to A pathway, where visual observations are projected into the representation space of a large language model before being decoded into robot actions. Although effective, this design incurs substantial computation and memory overhead at every policy invocation. In this work, we introduce TurboVLA, a new VLA paradigm that reformulates the conventional V to L to A pathway as a direct V + L to A mapping. Instead of using a lar

πR^2: Reactive Real-time Flow Policies

By Sungjae Park, Shubham Tulsiani

88 score
AI Analysis

piR^2 introduces reactive real-time flow policies for robot manipulation by leveraging diffusion forcing to enable mid-execution sensory replanning. It overcomes the latency bottlenecks of traditional action-chunking models.

Generalist manipulation policies increasingly take the form of action-chunking flow policies built on large pretrained backbones. Such chunks run open-loop, so the policy cannot react to sensory input arriving mid-execution, sacrificing reactivity. Replanning more often would restore it, but the perception-to-action pipeline (a large backbone plus multiple denoising steps) is too slow: this latency forbids frequent replanning and leaves committed actions stale, making such policies ill-suited fo

Memory Decoder at Scale: A Pretrained, Parametric Long-Term Memory

88 score
AI Analysis

Memory Decoder at Scale scales parametric long-term memory modules up to 6.9B parameters using a distributed Faiss indexing and retrieval pipeline. It shows superior parameter-performance tradeoffs compared to scaling base models.

Decoder-only language models entangle long-term memory and reasoning in a single parameter set, making it difficult to scale memory capacity independently. Memory Decoder introduces a parametric long-term memory module but only studies it at a relatively small scale. In this work, we present Memory Decoder at Scale, scaling memory models up to 6.9B parameters and pretraining them on 300B tokens. At this data scale, the combined cost of indexing and search makes a standard Faiss pipeline infeasib
