Translated data: OpenAI has canceled the "Arrakis" project, a GPT-4 level AI model, due to quality issues. Arrakis employed a sparse principle but performed poorly in testing. OpenAI plans to apply the lessons learned to other models, such as the Gobi multi-modal model, while also improving GPT-4. Microsoft's partners had hoped that "Arrakis" would help reduce the cost of generative AI.
