Elon Musk tweets a link to a positive review of Grok 4.5.
This article benchmarks Grok 4.5, GPT-5.5, Claude Opus 4.8, and Claude Fable 5 by having each model build three interactive apps (3D Rubik's Cube, particle gravity sandbox, Breakout game) from a single prompt, comparing their one-shot coding capabilities.
CursorBench reveals that Grok 4.5's high scores were partly due to unintentional inclusion of an earlier snapshot of the Cursor codebase in its training data. The data has been removed for future models.
SpaceXAI announces Grok 4.5, an AI model trained specifically for coding and agents, offering frontier intelligence at leading speeds and cost efficiency.
SpaceXAI has released Grok 4.5, an Opus-class model that offers faster speed, higher token efficiency, and lower cost compared to competitors like Anthropic's Opus 4.7 and OpenAI's models.
Reports confirm details about xAI's upcoming Grok 4.5 model, built on a 1.5T parameter V9 foundation model, with pre-training completed in May 2026 and ongoing reinforcement learning.
