On March 29th, Beijing time, Elon Musk's artificial intelligence startup xAI announced the official launch of Grok-1.5
According to the official description, for the context window, Grok-1.5 directly improves on the previous 16 times, growing to 128k, on par with GPT-4. This means that Grok-1.5 can handle longer and more complex cues while maintaining its ability to follow instructions.
One of the biggest improvements in Grok-1.5 is the vastly improved ability to handle programming and math-related tasks, outperforming Grok-1, Mistral Large, and Claude 2 across the board.(Source: FastTech)
