Choose detail deliberately for cost control.","On newer GPT-5.5 and GPT-5.6 models, 'auto' and the omitted default behave as 'original'. This is a behavior change if you are migrating from older models tuned for 'auto'.","image_generation_call returns base64 in 'result', NOT a downloadable URL. You must decode and persist it yourself.","Image generation pricing depends on the underlying image model, so cost forecasts built on a single flat rate will drift.","Not every model supports every detail level. Confirm support on the model page before assuming 'original' is available.","OpenAI docs moved: platform.openai.com/docs/guides/* now 302-redirects to developers.openai.com/api/docs/guides/*.
