Not a cost prediction—just the relative spacing of OpenAI’s announced tier multipliers. Dollar amounts in the table are the multipliers applied to this page’s list input and output rates.
OpenAI list prices in context
Common OpenAI API list points (GPT-4o family, o3) next to announced GPT-5.5 and GPT-5.5 Pro. Sourced to openai.com/api/pricing for older models; confirms against that page as prices move.
Highlighted bars: this page’s model. Other rows use the same public OpenAI list points as our catalog seed. Chart: left bar = input $/1M, right = output $/1M (grouped).
Frontier list prices (rough peers)
One cross-provider cut so you can see how announced GPT-5.5 pricing lines up with other often-cited list rates (Anthropic, Google, O3). Figures are static snapshots for illustration—always verify on each provider.
Peer rows use directional list pricing from our catalog seed. Your contract may differ. Highlight = this page’s announced model. Use the main catalog for live resellers and history.
