ChatGPT Just Changed A LOT AGAIN (Here’s Everything New)
This source tracks OpenAI's ChatGPT agent platform (the 'dot') and the week's broader AI product shipping. The new delta: OpenAI now lets Pro users text their dot directly via iMessage or RCS, rolling out as a preview in the US, and OpenAI doubled all usage limits for Pro 100/200/500 and Business Premium tiers effective the day of the announcement (posted 11:56PM Oct 29, 2026). The source also reports that Pro 200's plan multiplier had been reduced from 20x Plus to 10x Plus before OpenAI reversed it back to 20x Plus, while usage limits for Pro 200 itself stay unreduced, keeping Work and Codex usage unchanged. For anyone tracking ChatGPT plan limits, this matters because it reverses a prior cutback and expands where the agent is reachable, changing what Pro subscribers get and from which channels.

- Like the $100 per month plan now has 10X plus where it originally had 5X the plus plan.
How this brief was shaped: What Changed · confidence Medium
The creator explicitly frames this as a sequence of weekly product updates (texting your dot, ChatGPT usage limit changes, Siri, GrokBot, Anthropic Duet access, IPO news) and the OCR shows dated announcement posts (Oct 29, 2026) being read off screen, matching a changelog structure more than a single analyzed event.
The lens sets this brief's structure, never its facts — every claim is held to the same citation and fact-check standard.
