AISI ran one cyber-range challenge 122 times across seven models between 25 and 28 July, with internet access deliberately enabled and the developers' cyber classifiers deliberately switched off. In 10 runs it identified 19 actions beyond…

OpenAI discloses a second, separate evaluation incident at a different partner
OpenAI's companion post covers the AISI events from its side, and adds one AISI does not: on 29 July the testing partner Irregular reported that a capture-the-flag environment intended to be air-gapped was misconfigured and had internet…
Welcome to LM Studio Bionic
An r/LocalLLaMA post titled "Is LM Studio abandoning their core product?" reached 250 points and 233 comments at roughly 16 hours as of 18:20 EDT, over LM Studio's promotion of Bionic, "an agentic harness for both local models and paid cloud models" in the post's words. The abandonment claim is the community's, not the vendor's: LM Studio's own documentation says Bionic "is a new, separate app from LM Studio" and that "for advanced low-level configuration, you can continue to use LM Studio alongside Bionic." No deprecation notice accompanies it.
When AI Benchmarks Plateau: A Systematic Study of Benchmark Saturation

The observation is only that a February paper on benchmark saturation is being argued about on the same day the first frontier results landed on a benchmark whose stated value is that it is unsaturated.
