SpaceXAI has launched Grok 4.5, a new ai model that reportedly focuses on price and speed, with some outlets noting an emphasis on token efficiency and aggressive pricing for coding tasks. The launch appears to position Grok 4.5 as a competitor to other ai models, including those from OpenAI and Anthropic. Grok 4.5 is said to offer faster performance and lower costs than rival models, with some reports suggesting it matches the performance of Opus-level ai at a lower cost.
