Grok 4.3 Explained: Features, Demos & The Settings That Matter

Link to our newsletter: https://bitbiased.ai/
Grok 4.3 is xAI’s new flagship, and most people are leaving its best features on the table. In this full guide I break down everything it actually does — the 1 million-token context window, adjustable reasoning, tool calling, and structured outputs — with live demos for documents, coding, and tools so you know exactly when to reach for it and how to get your money’s worth.

I cover the controls that actually move the needle, the settings that quietly cost you money, and the pitfalls xAI buries in their own docs. By the end you’ll know precisely where Grok 4.3 wins, where it doesn’t, and how to beat the December 2025 knowledge cutoff.
