Grok 4.3 lands, and cross-tab sync gets leaner
Grok 4.3 is now selectable alongside the rest of xAI's models in Anuma — xAI's latest, drop-in available across the model picker. Behind the scenes, the cross-tab streaming pipeline switched from full-snapshot updates to deltas, so multi-tab chats stay in lockstep with less bandwidth and quicker convergence under heavy streaming. A small chat-history fix rounds out the week: synthetic tool-result placeholders no longer leak into the model's view of your conversation history, keeping answers grounded in what you actually said.
