xAI’s Grok Code Fast 1 has already surpassed over 400 billion tokens on OpenRouter during only one week of availability and taking the lead as the highest performing AI model on OpenRouter.
Grok Code Fast 1 by xAI is now leading the leaderboard of OpenRouter’s AI Model Rankings with about 420B tokens in use for just this week.
This achievement demonstrates increased use of the model by developers to complete coding tasks.
Elon Musk, spread the news on X (with a major Grok Code upgrade coming next month that will ‘one-shot many complex coding tasks’).
What the Leaderboard Reveals
OpenRouter, which routes API calls to different LLMs based on performance and cost, measures production usage via token volume, a metric of how frequently models are queried in production.

The superior performance of Grok Code Fast 1 indicates that it is faster and more efficient in processing coding questions quickly and accurately.
Here’s a snapshot of the current top rankings by token volume (as of early January 2026):
| Rank | Model | Token Volume | Market Share |
|---|---|---|---|
| 1 | Grok Code Fast 1 (xAI) | ~430B | 4% |
| 2 | Claude Sonnet 4.5 (Anthropic) | ~468B | 38% |
| 3 | Gemini 2.5 Flash (Google) | ~366B | 4% |
(Data obtained from OpenRouter rankings; please be aware that token volumes vary on a weekly basis.)
This places Grok higher in specialized coding applications and further ahead of competitors based on raw developer preference.
Community Reactions and Implications
