Executive TL;DR30s read

OpenAI is set to announce a new always-on agent and a $500 subscription tier at DevDay, potentially featuring the Aeon model.

OpenAI is preparing to unveil significant product updates at its upcoming DevDay conference. The highlight appears to be a new always-on agent, currently referred to by the codename «o».

Agent Details

According to leaks, mentions of this agent have already appeared on the ChatGPT plan update screen for some users. Its key feature is the ability to operate continuously, even outside of standard chat sessions. Speculation suggests the agent might have its own email address or constantly monitor the user's inbox.

Under the hood, rumors point to the Aeon model — a variant of GPT-6 Astra optimized for handling long-running tasks.

$500 Subscription Tier

Alongside the agent, OpenAI is reportedly launching a premium subscription priced at $500. Currently, the only described difference from ChatGPT Pro is "Fastest work in Work and Codex," which likely hints at the use of Cerebras infrastructure (Project Astra/Sol).

Caveats

It is important to note that this information is based on leaks. There is a possibility that the "o" agent will be exclusive to the new $500 tier and not available to standard subscribers.

Why it matters

Analysis

This move signals a shift from reactive chatbots to autonomous, background-operating agents, while testing the market's willingness to pay for ultra-premium AI capabilities.
