I thought the same about xAI / Grok, and was surprised to see the Grok Code Fast 1 at the top of the list for number of reasoning tokens processed in Open Router’s state of AI report that came out this month: https://openrouter.ai/state-of-ai#reasoning-models-now-repre

According to the model card it is extremely fast, can be hijacked 25% of the time, has access to search tools, and has a propensity for dishonesty. I also think it is optimistic to think the jailbreak percentage will stay at "0.00" after public use, but time will tell. https://data.x.ai/2025-08-26-grok-code-fast-1-model-card.pdf
