This article summarizes several core updates announced at OpenAI DevDay: the introduction of Dot, a 24/7 online resident agent with an independent identity and cloud-based operating environment; the creation of ChatGPT Space, a shared workspace for humans and agents; the release of GPT-6.1 Sol, a model with capabilities close to GPT-6 but priced at only one-fifth of its cost; the launch of Ultrafast mode, which can increase token generation speed by several times at its peak; and the introduction of Pro 500, a premium subscription service priced at $500 per month. Additionally, several upgrades have been made to Codex, the plugin system, and more. The core direction of this release is to transform ChatGPT from a product that responds to demands into an agent system that undertakes long-term tasks. Model capabilities are no longer the focus, and AI subscriptions have shifted from metering based on model calls to providing a complete suite of agent services. Furthermore, these updates have also sparked some controversy. The available quota for the new Pro 200 subscription, when converted, is only half of that of the old version. Moreover, agents like Dot have not yet been granted key real-world permissions such as payment and transactions, limiting their autonomy.
