Grok 4.3, time-aware bar charts, under-the-hood updates

Grok 4.3, xAI's latest reasoning and vision model, is now available across the AI chat and analysis flows, and as the default model for data extraction. A faster low-reasoning variant is available for text interview deployments where response latency matters more than depth. Existing sessions on the previous Grok 4 generation transparently route to Grok 4.3.

The research analyst chat now keeps time-based horizontal bar charts in chronological order. When the AI charts data across weeks, months, or sequential stages, the bars stay in order instead of being re-sorted by value.
