Elon Musk says Grok 4.8 has finished pre-training, is now in reinforcement learning, and will get a soft rollout to Bot users later this week
@elonmusk on X published this on Nov 10, 2026 (source: x.com).
In a 10 November 2026 post, Elon Musk said xAI had dumped JAX/SGLang and rewritten its entire reinforcement-learning and inference stack from scratch in C/C++, which he said took extra time. He said pre-training is done, that a lot of cleanup was needed on the supervised fine-tuning data, and that Grok 4.8 is now in reinforcement learning, with evaluation scores starting to climb. He said the company will do a soft rollout to Bot users later this week. Musk also said Grok 4.8 will bear no resemblance to 4.7, that it is not yet incredible, and that he expects it to evolve because, in his words, the foundations are built right. This is a new progress update, not a restatement of his September remarks that Grok 4.8 was a 2.5T model finishing training on a C++ stack.

SpaceXAI's Grok 4.7 is now available on Amazon Bedrock. AWS's launch post builds a tool-calling agent on the model and tests it on three search-heavy tasks at every reasoning effort level, six runs each. AWS reports 67 of 72 runs correct, with all 18 correct at xhigh effort and 15 of 18 at low effort while using about an eighth of the output tokens. The post shows how to tune that trade-off per request and monitor it in production.
