Who is selling these with enterprise trappings? What you're describing evaporated 2+ months ago. Everything is metered for enterprise users now. If there happens to be a stray vendor offering this I'd wager 2 things. 1) it's about to be phased out. 2) model limits will be in place so even that $200 plan won't go very far.
Are we talking about the same thing? I just double-checked Anthropic still offers per-seat plans. So does OpenAI though they split the Codex-only plan away from per-seat. Gemini does as well. There’s pooled usage over certain limits but it’s still a good deal to upgrade the seat of a heavy user.
