Opus 4.6 and Codex 5.3 Just Dropped at the Same Time! They Not Like US?!

In this episode, Danny and Leon break down a massive 48 hours in AI. With the surprise drop of Anthropic Opus 4.6 and OpenAI’s Codex 5.3, the landscape for software engineers has shifted again. We dive deep into what a 1-million-token context window actually means for your workflow, the rise of Agent Teams, and why "vibe coding" recently led to a massive security blunder in the dev community. We also answer a listener question about whether custom code or off-the-shelf builders like Shopify are the right choice for small business clients.
