OpenAI is winding down its GPT-4 AI model in ChatGPT – TechCrunch

🔍 Summary:

OpenAI has announced that it will retire its AI model GPT-4 from ChatGPT on April 30, replacing it with the more advanced GPT-4o, which is already the default model. GPT-4, launched in March 2023, was notable for its multimodal capabilities, processing both images and text. Despite its capabilities and a hefty $100 million training cost, GPT-4 will still be accessible via OpenAI’s API after its retirement from ChatGPT. The newer GPT-4o model has shown superior performance in various tasks including writing and coding, thanks to recent enhancements that improved its instruction following, problem-solving, and conversational abilities. Additionally, OpenAI is developing a series of new models, including GPT-4.1 variants and new reasoning models, indicating ongoing advancements in their AI technology. This transition occurs amidst ongoing copyright disputes involving GPT-4, with publishers like The New York Times contesting OpenAI’s use of their content without permission, a claim OpenAI counters by citing fair use protections.
