Can I upgrade individual users in my Teams Account to ChatGPT Pro?

The entire company I work at has all of their engineers on Anthropic, I’m the only exception. And although it shouldn’t be my concern as an Engineer; it does nonetheless greatly bother me that everyone is willingly entering into vendor lock-in. (Especially around Anthropic’s software stack.) The lack of Pro seats is one of the contributing factors. ~10M tokens/5h for GPT-5.5 at standard cache hit rates just doesn’t cut it for daily work. You have to either resort to GPT-5.4-mini, getting an inferior experience, or going for API Credits, where unpredictable billing can be a hard sell. Compliance wants verified vendors; and don’t want devs to use own tools. So folks like I are either stuck with Anthropic/Google (where I don’t want to be), or with too restricting limits. Folks who want to use Open Source tools and harnesses are screwed.
