We also break down OpenAI's surprising decision to adopt Google DeepMind's SynthID watermarking across ChatGPT, Codex, and the OpenAI API, marking a rare moment of interoperability between rival frontier labs. From Sundar Pichai's pitch on token budgets to Liz Reid declaring Google Search is AI search, we examine how Google is taking direct aim at Claude Code, Codex, and Perplexity while reshaping the agent ecosystem. https://www.aiconvocast.com Help support the podcast by using our affiliate links: Eleven Labs: https://try.elevenlabs.io/ibl30sgkibkv Disclaimer: This podcast is an independent production and is not affiliated with, endorsed by, or sponsored by Google, OpenAI, Anthropic, DeepMind, ElevenLabs, or any other entities mentioned unless explicitly mentioned.
