// how we pick alternatives

An alternative must accept every input type GPT-5 Nano accepts (text, image), offer the same tool-calling and reasoning support, and have at least half of its 400K-token context window. Models are sorted by blended price (3 × input + output) / 4, using base-tier list prices refreshed daily.
