Images 2.6: set edit complexity explicitly

OpenAI’s [November 4 launch](https://openai.com/index/introducing‑images‑2‑6/) adds `complexity`, a separate planning control, to Images 2.6. It recommends `low` for most edits. The [API guide](https://developers.openai.com/api/docs/guides/image‑generation) says both Sunburst and Flare use `high` when `complexity` is omitted. `quality` controls rendering: a low‑quality request does not select low‑complexity planning. For a focused change, explicitly request `low` if following OpenAI’s recommendation. The guide cautions that higher planning can add latency and unwanted changes; it does not promise a better edit.

For [SVG output](https://developers.openai.com/api/docs/guides/image‑generation), use `/v1/images/generations` with `n=1`. The result is static vector content; image edits cannot return it. GIF output works with generations or edits, and edits can take still references. Neither format supports streaming or partial images. GIF frame counts and dimensions must also fit the request’s pixel budget.

OpenAI’s [system card](https://deploymentsafety.openai.com/chatgpt‑images‑2‑6) explicitly lists GIFs and photo markup in ChatGPT and the API, but SVG support in the API. That identifies feature locations; it does not establish that every API control is exposed in ChatGPT or Codex. The [guide](https://developers.openai.com/api/docs/guides/image‑generation) mixes 2.5 examples with 2.6 sections. Check the model named in an example before copying it; these are documented controls, not OpenTools test results. Archive: digital drawing, 2017; not Images 2.6 output.
