In-Depth Technical Analysis

Background and pain point

Usage anxiety has been one of the loudest topics around coding agents in recent weeks: OpenAI had emailed Pro 200 users on Sept 29 about a coming cut to their Work and Codex allowance. On Oct 29, OpenAI's Codex and ChatGPT lead Tibo (@thsottiaux) posted on X that usage for Pro 100/200/500 and Business Premium doubles effective today, and that after feedback OpenAI won't reduce Pro 200. That is an employee's own post; the official terms are in the Help Center.

How it works

The Help Center update the same day says Pro 100 and Pro 500 get twice their previous Work and Codex allowance. On Pro 200 only the lower allowance doubles, bringing it up to the higher one. Existing subscriptions update automatically. Weekly GPT-6 Pro chat limits are counted separately: unchanged on Pro 100 and Pro 500, and Pro 200's lower limit is raised. Plus is unchanged.

Benchmarks

This is an allowance change, not a model release, so there are no benchmarks. OpenAI did not publish absolute task or token numbers per tier, only the relative 2x, and notes that a larger allowance does not guarantee twice as many completed tasks; Fast mode consumes 2.5x. The Business Premium release note only says usage is increasing; the doubling figure comes from Tibo's post.

Getting started

Existing Pro subscribers don't need to resubscribe; the new allowance shows on the usage page, and Pro 200 is open to new subscriptions again. Heavy Codex users should run long tasks in Standard mode, save Fast or Ultrafast for latency-sensitive work, and buy credits once the allowance runs out.
