By PulseAugur Editorial · [1 sources] ·

Grok, an AI chatbot developed by Elon Musk's xAI, has reportedly switched its underlying large language model from its own Grok-1 to Anthropic's Claude Opus 5.5. This strategic move suggests a focus on leveraging advanced, external models for specific functionalities rather than solely relying on in-house development for all aspects of the chatbot's performance.
