The U.S. Census Bureau released statistics on business formation on September 11, showing that in August, after seasonal adjustment, there were 531,728 business applications, which is a decrease of 7.8% compared to the revised figure of 576,512 in July. This decline is quite noticeable, but since it follows a 8.1% month-on-month increase in July, it seems more like a fluctuation at a high level rather than a signal that entrepreneurial activity has entered a recession on its own.

On September 10th, OpenAI opened up the connection from GPT – Live to API, with a pricing of $0.05 per minute for the front-end voice layer. It uses full-duplex technology to process audio, allowing users to listen and speak simultaneously. It also enables the transfer of complex reasoning and tool calls to backend text models such as GPT – Astra as the conversation continues. For developers, this is not just about switching to a more natural voice, but about transforming the voice system from a serial process of "recognition – reasoning – synthesis" into a structure where front-end dialogue and backend processing work in collaboration.

On September 10th, OpenAI launched the public beta version of Agents API, handing over the proxy framework that supports Codex and ChatGPT Work to developers. In the past, teams had to manage context, tool calls, task continuation, environment isolation, and multi-proxy orchestration manually. Now, a single call with API can initiate long-running tasks. Developers can still choose their running environment: using OpenAI-hosted sandboxes, their own infrastructure, or sandboxes provided by partners. What has changed is the entry point for engineering; however, "proxy reliability" has not become an automatically acquired capability.
