Description
Grok 4.8 is an upcoming large language model from xAI designed to continue the company’s push toward more capable coding, reasoning, knowledge work, and autonomous AI agents. Elon Musk has stated that Grok 4.8 uses approximately 2.5 trillion parameters, making it larger than the 2.1-trillion-parameter Grok 4.7 model previously discussed. The model is also being trained on a new C++ software stack that xAI expects to use for its next generation of large-scale training runs. Initial model training is expected to finish before reinforcement learning and additional post-training work begin, meaning the final production model is not yet available. Based on the current Grok generation, Grok 4.8 is likely to emphasize software engineering, agentic tool use, professional knowledge work, image understanding, and complex multi-step reasoning. Grok 4.7 currently supports configurable reasoning levels and a 500,000-token context window, providing a baseline for the capabilities xAI is developing further. Grok 4.8 may also become an important model for products such as Grok Build and Grok Bot, where stronger reasoning and tool coordination can support longer autonomous workflows. xAI has not published official Grok 4.8 benchmarks, pricing, context limits, API details, or an exact release date. Grok 4.8 is expected to serve developers, engineering teams, researchers, enterprises, and AI agent builders seeking frontier-level performance across technical and professional tasks.
