OPENAI DEVELOPS PLATFORM FOR ALWAYS-ON AGENTS ON CHATGPT

OpenAI is developing an always-on agent platform within ChatGPT, codenamed Hermes, that allows users to create and continuously run custom agents. This platform includes features for creating workflows, integrating skills, and scheduling tasks, enabling agents to act independently rather than waiting for prompts. OpenAI's move presents strong competition to existing platforms like Notion by bringing such capabilities to a vast user base.

QWEN3.5-OMNI TECHNICAL REPORT

Qwen3.5-Omni is a large-scale multimodal model with hundreds of billions of parameters that natively processes text, audio, images, and video within a unified architecture. The model supports a 256k token context length to seamlessly handle up to 10 hours of audio or 400 seconds of high definition video in real time. It leverages a Hybrid Attention Mixture of Experts framework alongside a dynamic alignment technique called ARIA to generate highly stable and emotionally nuanced multilingual speech synthesis with minimal latency.

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.

STITCH'S DESIGN.MD FORMAT IS NOW OPEN-SOURCE SO YOU CAN USE IT ACROSS PLATFORMS.

Stitch's DESIGN.md lets users export or import design rules from project to project. Stitch understands the reasoning behind design systems and can generate user interfaces that match branches. Google has open sourced the draft specification for DESIGN.md, which can be used across any tool or platform. A video breaking down the format is available in the article.
