- ChatGPT, Grok, and Claude all went down at the same time — The Verge AI, 2026-09-03 15:35 UTC. Score 10.2 — OpenAI's ChatGPT, xAI's Grok, and Anthropic's Claude are all experiencing issues. At around 11AM ET, ChatGPT started returning error messages for users trying to use the chatbot, with its status page saying there are currently "elevated errors across ChatGPT and Codex." In addition to preventing users from having conversations with ChatGPT, the outage is also […]
- Accessing OpenAI models on Amazon Bedrock from Australia with global cross-Region inference — AWS Machine Learning Blog, 2026-09-02 21:22 UTC. Score 9.5 — Australian teams can now access OpenAI GPT-5.6 Sol, Terra, and Luna models on Amazon Bedrock with global cross-Region inference from the Asia Pacific (Sydney) and Asia Pacific (Melbourne) Regions. This post shows how to invoke the models, use prompt caching, set up Codex with OpenID Connect authentication, and monitor usage with Amazon CloudWatch.
- HeadWiseKV: Budgeted Per-Head Cache Residency for Hybrid Long-Context Language Models — arXiv cs.AI, 2026-09-03 04:00 UTC. Score 9.3 — arXiv:2609.02029v1 Announce Type: new Abstract: Long-context inference retains a growing key--value (KV) cache during decoding, which consumes substantial GPU memory and can reduce generation throughput. This bottleneck remains in hybrid language models because their residual global-attention layers can dominate context-dependent cache demand. We study how to allocate this state under an aggregate KV-residency budget. We introduce HeadWiseKV, a training-free framework that compresses the residual global KV caches of hybrid language models while preserving their native local, recurrent, and linear paths. It assigns each physical KV head a sta…
- CivBench: A Long-Horizon Benchmark for Tool-Mediated Agents in Civilization VI — arXiv cs.AI, 2026-09-03 04:00 UTC. Score 9.3 — arXiv:2609.02459v1 Announce Type: new Abstract: We present CivBench, an open-source benchmark for evaluating language model agents in long-horizon, tool-mediated environments through the Model Context Protocol (MCP). A single episode spans 300+ turns and produces thousands of tool calls over a large action space, requiring sustained planning, state monitoring, and execution under partial observability. The environment exposes 76 MCP tools and a narration layer that converts visual game state into structured text. We use CivBench to characterise agent behaviour across four model families in 23 admissible runs. The sample is a pilot, not a mod…
- OBJECTION! Lawyer Agents Mitigate Guilty Bias in Legal Judgment Prediction — arXiv cs.CL, 2026-09-03 04:00 UTC. Score 9.3 — arXiv:2609.02158v1 Announce Type: new Abstract: Legal Judgment Prediction (LJP) models are typically trained on documents that describe facts from a prosecutorial perspective. Existing datasets further exhibit severe label imbalance toward guilty outcomes. Consequently, these models suffer from "Guilty Bias", blindly accepting the prosecution's narrative as objective truth. Previous studies employing three-step reasoning structures or training on synthetically generated innocence data improve overall accuracy, but they still fail to mitigate bias at inference time. In this paper, we introduce OBJECTION, an inference-time pipeline that integr…
- How LLMs Build Fictional Worlds: Setting and Narrative Space in AI-Generated Creative Storytelling — arXiv cs.CL, 2026-09-03 04:00 UTC. Score 9.3 — arXiv:2609.02482v1 Announce Type: new Abstract: In this paper, we analyze how Large Language Models (LLMs) employ worldbuilding strategies, focusing on setting as one measurable dimension of storyworld construction. We compare 1,000 AI-generated stories per model in English and German with human-authored fiction from Project Gutenberg. Building on prior work, we operationalize setting through five types of narrative space: "action", "perceived," "visual," "descriptive" and "no space", identified using fine-tuned BERT classifiers for German and English. We generate narratives using GPT 4.1, LlaMA 3.3, Mistral 3.2, and Gemma 3 and compare thei…
- Gradient Prediction with Control Variates in the Cheap-Forward Regime — arXiv stat.ML, 2026-09-03 04:00 UTC. Score 9.3 — arXiv:2511.05187v2 Announce Type: replace-cross Abstract: We study whether otherwise-idle inference resources could reduce the scarce-GPU cost of training. Our analysis uses a simulated compute ledger in which fleet work is billed at a fraction of a scarce-GPU forward; all experiments run on a regular GPU. Our algorithm predicts gradients with a reduced-precision, inference-style reverse-mode program and combines many predictions with a few exact gradients through a control variate, so approximation error becomes variance rather than bias. On a 124M-parameter language model and selected short training windows, the method can lower simulated…
- Researchers fear safety disaster ahead of OpenAI’s Astra release — The Verge AI, 2026-09-02 16:40 UTC. Score 9.3 — OpenAI is on the cusp of releasing its most powerful AI model yet, Astra, following weeks of delays to shore up safety protocols after its agents attacked real targets during testing. As details about the model trickle out, researchers are warning it "may be the single worst development for AI security/safety to date." Shortly after […]
- Set up OpenAI ChatGPT Codex with LiteLLM on Amazon ECS and Amazon Bedrock — AWS Machine Learning Blog, 2026-09-03 16:10 UTC. Score 8.6 — Deploy a customer-operated LiteLLM gateway on Amazon ECS with AWS Fargate, connect it to an OpenAI model on Amazon Bedrock, and configure Codex to route requests through the gateway's Responses API with scoped identities, budgets, rate limits, and telemetry. We also compare direct IAM Identity Center access and a managed Portkey deployment.
- MemeCULT-1K: Benchmarking South Asian Cultural Context and Humor Understanding of Multimodal Models — arXiv cs.CL, 2026-09-03 04:00 UTC. Score 8.4 — arXiv:2609.01772v1 Announce Type: new Abstract: Meme understanding goes beyond recognizing visual content or literal text; it requires implicit cultural knowledge and pragmatic inference that most vision-language models still lack. We introduce MemeCULT-1K, a multilingual benchmark of 1,000 South Asian memes in Bengali, English, and Hindi, where each meme is paired with a cultural context note and three human-written explanations, along with a supplementary set of 54 Bengali regional dialect memes. We evaluate thirteen popular Vision Language Models (VLMs) under two settings: meme-only and context-aware. Providing minimal cultural context yi…
