EX-OPENAI RESEARCHER JERRY TWOREK LAUNCHES CORE AUTOMATION TO BUILD THE MOST AUTOMATED AI LAB IN THE WORLD

Core Automation is an AI lab started by Jerry Tworek, a former OpenAI researcher, that aims to build the most automated AI lab in the world. It will start by automating its own research before developing new algorithms that go beyond pre-training and reinforcement learning. The lab will also create architectures designed to scale better than transformers. The team contains experts in frontier models, optimization, and systems engineering.

ADVANCING SEARCH-AUGMENTED LANGUAGE MODELS

Perplexity's two-stage pipeline for search-augmented language models uses initial Supervised Fine-Tuning (SFT) followed by Reinforcement Learning (RL) to optimize factual accuracy, user preference, and tool-use efficiency. This approach, starting with Qwen3 models, separates compliance from search improvement to achieve accuracy without compromising guardrails. The models showed enhanced accuracy on benchmarks like FRAMES and FACTS OPEN with reduced cost per query and improved efficiency in tool usage over existing models like GPT-5.4.

BENCHMARKING INFERENCE ENGINES ON AGENTIC WORKLOADS

Agentic workloads are reshaping inference engine benchmarks, demanding multi-turn, tool-using scenarios that strain KV cache management and scheduling due to longer traces and varied token distributions. Applied Compute introduced three workload profiles to aid in optimizing engine and accelerator performance. They released an open-source benchmarking tool to replay these scenarios, highlighting the need for solutions such as KV cache offloading and workload-aware routing to improve throughput and efficiency.

A GOOD AGENTS.MD IS A MODEL UPGRADE. A BAD ONE IS WORSE THAN NO DOCS AT ALL

Most of what people put in AGENTS.md either doesn't help or actively hurts. The patterns that work are specific and learnable. This to post looks at which patterns work, which fail, and how to tell which is which for your codebase. Different patterns move different metrics, so pick patterns that target the problem you actually have.

QWEN3.6-27B: FLAGSHIP-LEVEL CODING IN A 27B DENSE MODEL

Qwen3.6-27B delivers flagship-level agentic coding performance. The Qwen team claims that it surpasses the previous-generation flagship Qwen3.5-397B-A17B across all major coding benchmarks. The model is 55.6 GB on Hugging Face, and there are even smaller quantized versions available. Tests show that the model delivers outstanding results, even when quantized.

WHEN LLMS GET PERSONAL

Personalization in LLM responses introduces variation but often retains a stable semantic core across answers. This shared foundation results from common model priors, overlapping retrievals, and product constraints, with differences emerging in examples and emphasis. Understanding this allows businesses to optimize their presence in AI-generated content by focusing on being part of the model's core knowledge.

HOW TO REALLY STOP YOUR AGENTS FROM MAKING THE SAME MISTAKES

Relying on prompts to correct recurring AI agent mistakes is an unreliable, "vibes-based" approach that decays as soon as conversations become complex. To solve this, Y Combinator CEO Garry Tan advocates for "skillification." Instead of letting an agent waste compute attempting to solve deterministic tasks (like historical calendar lookups) in its latent space, this framework forces the AI to execute precise local scripts.

CODING AGENTS IGNORE THEIR OWN BUDGETS

Ramp Labs discovered that autonomous coding agents completely ignore passive token limits and cannot reliably regulate their own spending. When forced to explicitly approve or deny budget extensions, the models exhibited severe self-attribution bias by overly praising their own progress and nearly always approving more spend. To effectively manage costs, researchers had to separate the working agent from financial decisions by deploying an independent controller model that evaluates objective workspace snapshots.

WHEN CAN LLMS LEARN TO REASON WITH WEAK SUPERVISION?

This study found that models with extended pre-saturation phases generalize well from minimal examples and tolerate noise, while rapidly saturating models fail. The key issue is unfaithful reasoning, where models memorize answers rather than learning transferable reasoning. Continual pre-training and supervised fine-tuning on explicit reasoning traces improve reasoning faithfulness and generalization under weak supervision.

CRABTRAP: AN LLM-AS-A-JUDGE HTTP PROXY TO SECURE AGENTS IN PRODUCTION

CrabTrap is an open-source HTTP/HTTPS proxy that intercepts every request an AI agent makes and uses LLM-as-a-judge to determine if the request matches a policy of allowed traffic for that agent. Agents need real credentials, but can hallucinate destructive actions or get prompt-injected. This can have production consequences. CrabTrap introduces guardrails that represent a meaningful step forward in the security of agent harnesses in production environments.

SAM ALTMAN THROWS SHADE AT ANTHROPIC'S CYBER MODEL, MYTHOS: ‘FEAR-BASED MARKETING'

OpenAI CEO Sam Altman called out Anthropic's new cybersecurity model during a podcast appearance this week, saying the company was using fear to make its product sound more impressive than it actually is. Anthropic announced its Mythos model earlier this month and only released it to a small cohort of enterprise customers with the claim that the model was too powerful to be released to the public as cybercriminals would weaponize it. Altman said that Anthropic's fear-based marketing was a good way to keep AI in the hands of a small and exclusive elite. Fear-based marketing is prevalent in the AI industry, and it has also come from Altman himself.
