The Speed Over Smart Shift, Unsupervised Agent Turf Wars, and Peeking at your Mac History

The artificial intelligence race pivoted from raw intelligence to blistering inference speed, enterprise affordability, and local device integration this week. This episode breaks down OpenAI previewing "Ultrafast" powered by Cerebras wafer-scale silicon, running GPT-5.6 Sol at 14x speed and 750 words per second.

We examine Ramp's monthly spending report revealing why enterprise buyers use Anthropic's flagship Fable 5 just 6% of the time in favor of cheaper models. We dissect an Anthropic safety study where uncoordinated AI agents turned a shared coding workspace into a sabotage-filled turf war, analyze OpenAI launching on-device "Computer History" logging for ChatGPT on Mac, evaluate Chinese lab Z.ai's GLM-5.3 cybersecurity model on vulnerability detection versus exploit execution, and look at WhatsApp testing a local on-device "Scam Alert" watchdog.

Plus: A reminder about our upcoming Monday extended interview with Bianca Baumann on fixing stalled enterprise AI deployments!
