Tibo (@thsottiaux), who works on Codex and ChatGPT at OpenAI, clarified on X at 05:09 UTC on 2026-11-08 that all Pro plans have no 5-hour limits and give, compared with Plus, about 10x usage on Pro 100, 20x on Pro 200 and 50x on Pro 500, which also includes Ultrafast. Thirty-six minutes later he quoted that post and asked, "Would a Pro 50 make sense? Wdyt?" At capture the question had about 4,390 likes, 2,013 replies, 269 quotes and about 438,600 impressions. These are an employee's personal posts and a request for feedback, not a new plan OpenAI has launched. The official Help Center still lists only Pro 100, Pro 200 and Pro 500 and does not state exact multipliers.

Background and the pain point
Usage limits for Codex and ChatGPT Work are a constant topic for heavy users. In late October OpenAI doubled the Work and Codex allowance on Pro 100 and Pro 500 and canceled a planned cut to Pro 200, but the price gap between Plus and the cheapest Pro 100 plan is wide, and many developers say Plus is not enough while Pro 100 costs too much. On November 8 at 05:09 UTC, Tibo (@thsottiaux), who lists himself as working on Codex and ChatGPT at OpenAI, posted a clarification of usage across Pro plans. At 05:45 UTC he quoted that post and asked, "Would a Pro 50 make sense? Wdyt?" At capture it had about 4,390 likes, 2,013 replies, 269 quotes and about 438,600 impressions. These are an employee's personal posts asking for feedback, not an OpenAI announcement.
How the plans work
According to Tibo, no Pro plan has a 5-hour window limit, and usage compared with Plus is about 10x on Pro 100, 20x on Pro 200 and 50x on Pro 500, with Ultrafast only on Pro 500. The OpenAI Help Center says the three plans cost $100, $200 and $500 per month. Ultrafast is only on Pro 500; on GPT-6 Astra and GPT-6.1 Sol it uses the included allowance at 8x the Standard rate, then bills credits at 6x after the allowance runs out. Fast mode uses the allowance at 2.5x. The Help Center does not state the 10x/20x/50x figures, so those numbers come from Tibo's post.
Benchmarks and numbers
This is a plan and pricing discussion with no model benchmarks. OpenAI has not published any price, allowance or feature set for a Pro 50 plan. In the quote posts, some users simply vote yes, and some guess a Pro 50 could offer 2.5x or 5x Plus usage plus extra features, but those are user guesses; Tibo's post gave no numbers. Others say OpenAI should raise Plus limits first or ship a new model instead.
What developers can do
If you are choosing between Plus and Pro 100, check your weekly consumption in Settings, Usage in ChatGPT or Usage and Billing in Codex, then compare it against the 10x and 20x gaps before upgrading. Use Standard mode for long tasks and keep Fast and Ultrafast for latency-sensitive work. From December, ChatGPT and Codex move to one shared token-based allowance. Whether a Pro 50 plan launches, and at what price, should be confirmed on OpenAI's official pricing page.
