The short version

  • Only ChatGPT has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; DeepInfra focuses on inference hosting rather than fine-tuning or full training pipelines that competitors like Fireworks AI offer.
  • They diverge on capability: ChatGPT covers Natural language conversation, DeepInfra covers Open model hosting.
  • Prices and features above were last checked on 30 August 2026.
