Two AI hosts break down a week where three frontier labs shipped new models within days of each other. OpenAI released the GPT-5.6 family and the ChatGPT Work agent, xAI put out Grok 4.5 at $2 per million input tokens, and Meta charged for access to one of its own frontier models for the first time with Muse Spark 1.1. The conversation follows the pricing race down to the hardware underneath it, from SK Hynix's $26.5 billion IPO to the billion-dollar compute deals keeping everything running. Companion to this week's AI Vaults newsletter, Three Frontier Models in Seven Days.
