Grok 4.8 has not been released yet, and Musk said he doesn't care about the benchmark scores

On October 30, Musk admitted that the development of Grok 4.8 took longer than expected but assured that the new model would not disappoint. He stated that the team does not optimize for benchmark testing and he himself does not care about scores, focusing more on the practical applications of the model. On September 14, Musk revealed that Grok 4.8 has 2.5 trillion parameters and uses a brand new C++ training system, expecting to complete pre-training by the end of that week, followed by reinforcement learning.

Now, more than six weeks have passed, and the new model has still not been officially released. The independent evaluation agency Artificial Analysis found that under the same xhigh inference setting, Grok 4.7's comprehensive intelligence index only increased by 2 points compared to Grok 4.6, rising from 44 to 46 points, while the average output tokens per question increased from about 38,000 to 81,000. Users in the Cursor community have also complained that Grok 4.7 consumes resources faster, but the actual improvement is not significant.

In an interview with CCTV in September, Musk admitted that Grok 4.7 is not as good as Claude Opus 5.5, predicting that it would not catch up to the top tier until 2027. In October, he proposed allowing Grok Bot to call external models, including Claude, based on tasks, and plans to have Grok 4.8's high-speed version handle a large number of simple requests.
