According to CoinWorld, OpenAI's Chief Futurist, Joshua Achiam, announced his departure from the company on the 24th of this month. He publicly shared his farewell letter to the internal Slack community on X, stating that there was no specific reason for his departure, nor was it triggered by a particular point in time. He explained that after a period of reflection, he felt he could now continue to advance the mission of secure AGI outside of the cutting-edge labs. Achiam joined OpenAI as an intern in 2017, focusing on AI security research and previously serving as the head of the Mission Alignment team. In February of this year, after OpenAI disbanded the Mission Alignment team, he became Chief Futurist, responsible for researching the social, policy, and security impacts of AGI and stronger AI. In his farewell letter, he stated that the past nine years have felt like "a decade of change," and the future depends on the shared choices made by all parties regarding AGI and superintelligence. OpenAI has not yet announced who will succeed him in this role.

According to a report by CNBC, influenced by the continued price increases of AI models from leading US AI vendors, Chinese AI models are rapidly expanding in the US enterprise market due to their cost-effectiveness. Industry insiders point out that the performance of some leading open-source and open weighted models in China is currently about 6 to 9 months behind that of top-tier US models such as OpenAI and Anthropic, while their pricing is 60% to 90% lower, and they can cover the vast majority of routine AI tasks, making them highly favored by US companies. According to statistics from the AI model aggregation platform OpenRouter, since February 8th of this year, the percentage of terms used by US companies to call Chinese AI models has exceeded 30% weekly, reaching a peak of 46%, compared to an average of 11% over the previous 12 months.
