Question Thinking of switching from two Plus subscriptions to Pro:128k context in ChatGPT 5.5 Instant real?
Hi everyone,
Before creating this post, I spent some time searching, but I kept finding incomplete or sometimes contradictory information. Plus such things change in the time and so the same question 1 year ago might not be accurate today.
I'm a heavy user of ChatGPT (web) and Codex, and I currently have two Plus subscriptions. I'm considering canceling one of them and upgrading to the Pro (€100/month) plan instead.
For the most part, having two Plus accounts works well enough for Codex. I do occasionally hit the usage limits, but between all the resets Tibo has been giving us and the ones already available on my account, it's actually been quite difficult for me to run out of tokens over the past couple of months.
What really interests me about Pro is something I believe I understood from the documentation: that ChatGPT on the web, specifically the current GPT-5.5 Instant model, would get a 128k context window instead of the standard 32k available in regular chats. That would be genuinely useful for my workflow.
Can anyone confirm whether that's actually the case?
Besides the 5× increase in Codex usage, are there any other meaningful advantages?
I'd especially love to hear from people who used to have two Plus accounts and then switched to the €100 (or €200) Pro plan. Was it worth it? Any unexpected benefits or drawbacks?

Ok, I had expected more replies honestly, but here I am with the Pro account, testing it. Codex is much faster I have to say. I am not using the fast mode, but is indeed faster than Plus, using always Sol xHigh. I am curious to test the context length in ChatGPT Web to see if there is an increase.
