Prompt Caching Explained

Brian and Andy hosted this pre Thanksgiving episode and opened with platform issues, live chat glitches, and holiday energy in the air. They talked through the growing instability of their streaming setup and then shifted into the day’s news. The episode touched on the chip wars, new optical computing breakthroughs, OpenAI’s cameo trademark fight, the launch of OpenAI’s shopping assistant, Google’s Notebook LM upgrades, and Anthropic’s surprise release of Opus 4.5. The show ended with Brian demoing his Gemini powered “Infinite Bard” project and discussing why Gemini has become his default model for creative work.
