The 2026 video model lineup — what each one is actually good at (step 9/9) · ai video generation

Checkpoint

One last thing before we move on. pass this to mark the lesson done, or skip and keep moving. hop to the next when you're ready.

Final footage drill. Write lint_video_plan(plan, as_of) that takes a plan dict and an as_of date string ("YYYY-MM-DD") and returns "FAIL", "WARN", or "PASS".

Plan keys you will see:

video_model (str)
api_method (str): "interactions.create", "generate_videos", "generateContent", or "generate_images"
first_frame_model (str, may be "")
first_frame_method (str, may be "")
production (bool): True if this is the production default

Rules, evaluated in order. FIRST matching rule wins:

If video_model starts with "veo-2.0-" or "veo-3.0-" → "FAIL".
If first_frame_model starts with "imagen-4" → "FAIL".
If first_frame_method == "generate_images" → "FAIL".
If video_model == "gemini-omni-1.1-flash" AND api_method == "generate_videos" → "FAIL" (Omni goes through interactions.create).
If video_model starts with "sora-2":
- as_of >= "2026-09-24" → "FAIL"
- else if production is True → "WARN"
- else → "PASS"
If video_model == "gemini-omni-flash-preview":
- as_of >= "2026-09-30" → "FAIL"
- else → "WARN"
Else → "PASS"
