⬤ xAI's Grok 4.1 Fast just made waves with some crazy usage numbers on OpenRouter. The model jumped from 253 billion to 334 billion tokens in a single day, crushing its previous all-time record. November 28 marked the biggest activity spike the free version has ever seen, and the growth pattern shows this wasn't a fluke.
⬤ The activity chart tells the story pretty clearly. Usage had been climbing steadily through the week, bouncing between 170B and 260B tokens before absolutely exploding to 334B. That kind of jump destroyed everything else on the leaderboard, with Grok 4.1 Fast basically leaving other models in the dust during the same period.
⬤ Here's the thing: developers are gravitating toward Grok 4.1 Fast because it's built for exactly this kind of volume. With a 2 million-token context window and zero-cost tokens for both input and output, it's perfect for large-scale workflows. Customer-facing apps and research projects that need serious throughput are clearly finding what they need here.
⬤ This record-breaking surge shows how fast things move in AI right now. When a model proves it can handle massive workloads without breaking the bank, adoption explodes overnight. These kinds of spikes matter because they signal real market traction and show which platforms are actually winning developer mindshare in the fast-response AI race.
