The short version
- Only ChatGPT has a free tier, so it costs nothing to try first.
- Each has a real cost: Brex the free Essentials tier is limited to two legal entities; ChatGPT openAI's own pricing page, as captured by the Internet Archive in 2023, listed ChatGPT Plus at $20 per user per month, Team at $25 to $30 per user per month with a minimum of 2 users, and Enterprise available only from 150 users. The live page refuses automated reads, so these are 2023 figures and the tiers have changed since.
- They diverge on capability: Brex covers Corporate cards, ChatGPT covers Natural language conversation.
