Leaked OpenAI DevDay Rundown: Always-on Agents, Codex Cloud, Ultrafast

Ahead of DevDay, multiple social media accounts have been circulating a roundup of what OpenAI is supposedly about to launch, covering 20+ products and features. The overarching narrative: ChatGPT evolving from a chat box into a native application platform for "people + agents." None of it has been officially confirmed so far—only the DevDay event itself is confirmed.

Confirmed

• OpenAI DevDay will take place soon (@CodexResets1 confirmed the event timing).

Unconfirmed

• Models and subscriptions: GPT-6.1 Sol (@eyishazyer claims intelligence close to Astra at roughly one-fifth the price), GPT-6.5 Astra, GPT-6 Cyber, GPT-6 Aeon, ChatGPT Pro Max, and more (compiled by @iamfakhrealam).
• Persistent agents: 24/7 Always-on agents, aka "Dots" or the "O" agent, mentioned across multiple posts (@kimmonismus, @eyishazyer, @CodexResets1, @koltregaskes).
• Developer side: Codex in the cloud, persistent Codex agents, multiple Codex versions, Agents API, OpenAI marketplace, OpenAI's in-house "jev," Spaces collaboration features, and more.
• Ultrafast, an ultra-fast inference mode; @kimmonismus suggests it may be limited to the $500 tier. @koltregaskes and @CodexResets1 mention a first-ever $500–600 ChatGPT subscription plan, and @CodexResets1 also mentions a hardware device debut.
• @NFTChen relayed that a user found OpenAI had accidentally leaked a DevDay 2026 recap document (with 20+ updates) ahead of time—this claim is itself unverified.

Why it matters

If the list is accurate, it marks a strategic upgrade from "conversational product" to "agent platform" for OpenAI, and combined with a premium subscription tier and Ultrafast inference, could reshape ChatGPT's product form and pricing structure. The same items (always-on agents, cloud Codex, $500 tier, Ultrafast) appearing across multiple independent sources adds credibility to the rumors, but they should still be treated with caution until officially announced.
