> Choose a model, protocol, duration, resolution, and reference mode.

<AccordionGroup>
  <Accordion title="Which text protocols does SnapGen support?">
    SnapGen supports OpenAI Chat Completions, OpenAI Responses, Anthropic
    Messages, and Gemini native `generateContent` for the live GPT text routes.
  </Accordion>

  <Accordion title="Does SnapGen currently offer Claude text models?">
    No Claude model ID is in the current live catalog. Claude Code can connect
    through the Anthropic Messages-compatible protocol, but the selected model
    is a SnapGen GPT route.
  </Accordion>

  <Accordion title="Which Seedance 2 durations are available?">
    Both `video-ds-2.0` and `video-ds-2.0-fast` accept 5, 10, or 15 seconds.
    Prices are $1, $2, and \$3. Output is 720p.
  </Accordion>

  <Accordion title="Is familySlug part of the video API?">
    No. `familySlug` is an internal Portal value. Public video requests use
    `model`, `prompt`, `seconds`, and the model-specific framing fields.
  </Accordion>

  <Accordion title="Which Gemini Omni resolutions are available?">
    Choose a 720p or 1080p landscape or portrait `size`. Square output uses
    `1024x1024`. Each request generates a fixed 10-second result.
  </Accordion>

  <Accordion title="Which Veo 3.1 resolutions are available?">
    Model IDs without `-4k` produce 1080p. `veo3-1-lite-4k`,
    `veo3-1-fast-4k`, and `veo3-1-quality-4k` produce 4K. All Veo routes are
    fixed at 8 seconds.
  </Accordion>

  <Accordion title="How many Veo reference images can I send?">
    Lite, Fast, and Quality routes accept zero to two public image URLs.
    `veo3-1-fast-ref` requires one to three.
  </Accordion>

  <Accordion title="How do I discover newly added models?">
    Call [`GET /v1/models`](/api-reference/list-models) at runtime and check the
    [live models page](https://snapgen.org/models) for current prices.
