## Description

Generate and conversationally edit short videos with stable Google Gemini Omni Flash (`gemini-omni-1.1-flash`). Use when: (1) iterating on a clip with natural-language edits instead of regenerating ("make the phone invisible, keep everything else the same"), (2) generating 3-10s 720p clips with synthesized audio, rendered on-screen text, or timecoded beats, (3) binding reference images to roles with <FIRST_FRAME>/<IMAGE_REF_N> prompt tags, (4) editing an existing uploaded video. Accessed via the `gemini_omni_video` tool using the project's GEMINI_API_KEY/GOOGLE_API_KEY, the same key as Imagen and Google TTS.

# Gemini Omni Flash (Google DeepMind)

Gemini Omni is Google DeepMind's video generation **and editing** model family. The OpenMontage direct adapter uses the generally available **Gemini Omni 1.1 Flash** model (`gemini-omni-1.1-flash`) through the Gemini **Interactions API**. Its implemented baseline generates 3, 10 second clips at 720p/24fps with synthesized audio. Its differentiator in the OpenMontage fleet is **stateful conversational editing**: each stored generation returns an `interaction_id`, and a follow-up call with `previous_interaction_id` edits that video in place, no other wrapped provider can refine a clip without regenerating it.

OpenMontage wraps it as `gemini_omni_video` (native Gemini API, no gateway). It shares `GOOGLE_API_KEY`/`GEMINI_API_KEY` with `google_imagen` and `google_tts`, one key, three capabilities. Paid tier only: ~$0.10 per second of output video (exactly 5,792 output tokens/sec at $17.50/1M, before input and any text/thought output).

Other documented routes are available when the direct Google key is not the
chosen provider:

| Route | OpenMontage call | Important limitation |
|-------|------------------|----------------------|
| fal.ai | `gemini_omni_fal` | T2V, I2V, reference video, and edit endpoints; no Google interaction ID is returned |
| Runway | `runway_video`, `model: "gemini_omni_flash"` | T2V/I2V/V2V; video edits accept up to five image references |
| ComfyUI Partner Node | Not a stable 1.1 fallback in this adapter | The existing `GeminiVideoOmni` mapping targets the legacy preview node; migrate it separately to `GeminiVideoOmniV2` before claiming Omni 1.1 support |

Use the direct `gemini_omni_video` route for stateful conversational editing.
Gateway routes return ordinary provider tasks and cannot preserve Google's
`previous_interaction_id` workflow. The fal edit endpoint can still be iterated
by feeding each output video URL into the next edit call.
