According to CoinMeta, OpenAI DevDay 2026 will be held in San Francisco on September 29th, and at that time, CEO Sam Altman will face significant changes in the market. Over the past month, major tech platforms such as Google, Apple, Meta, and Microsoft have shifted to providing opinionated proxy products for finished products, while OpenAI remains the last major company without a proxy product specifically aimed at consumers. As a result, OpenAI retired four older models on September 28th, encouraging developers to switch to the new GPT-5.6-Terra alternatives. This move has paved the way for the platform's transformation under OpenAI, and it has also sparked speculation about its next steps.
