Grok 4.20 vs GPT-5.4 — everyone says they’re basically the same. They’re not. In this video, I break down the real differences between xAI’s Grok 4.20 and OpenAI’s GPT-5.4 based on first-party documentation, developer specs, third-party benchmarks, and hands-on building experience.

I cover context windows (2M vs 1.05M tokens), tool use philosophies (multi-agent vs tool search), hallucination rates, coding benchmarks, pricing, enterprise deployment, and give you a practical decision framework for choosing the right model for your workflow.

Whether you’re a developer picking your next API backbone or evaluating these models for enterprise use — this is the comparison that cuts through the marketing.
