> oxygen-1.0 parameter update: resolutions are now 480p / 768p with 320p retired; 768p output is now 1376×768; the input_reference envelope gains optional quality and prompt_enhance parameters. Default behavior is unchanged and the price stays at $0.02 per second.

🔧 **`oxygen-1.0` parameter update: resolutions are now 480p / 768p, plus two new optional parameters, `quality` and `prompt_enhance`**

This follows a provider-side API upgrade. The price is unchanged at \$0.02 per second:

* **320p retired**: sending `"resolution":"320p"` in the envelope returns 400 at submission and is not charged; use 480p instead
* **768p output size**: 1376×768 landscape, 768×1376 portrait; 1:1 stays at 768×768 and 480p is unchanged
* **`quality`**: quality tier, `high` (default) / `normal`
* **`prompt_enhance`**: `refine` (default, polishes and expands), `format` (tidies formatting only), or `none` (uses your prompt as written)

Both new parameters go in the `input_reference` JSON envelope. Their defaults match the previous behavior, so existing code that omits them needs no changes. See the [Oxygen Overview](/en/api-capabilities/oxygen/overview).
