Nano Banana 3: does it exist? Current ids

Autocomplete showing "nano banana 3" proves people search for it, not that a model with that name exists. On the read date, Google's suggestions for "nano banana" included 3 alongside pro, 2, gemini, ai, 2 pro, free, 2 lite and api. Do not put a guessed id into an API call; read the model list of the platform you call.

What the suggestion list shows

The table is the autocomplete response for the query "nano banana" on the read date. Order and wording are Google's and change over time, so this is evidence of interest and of naming patterns only.

Which id Sume accepts

The Sume Image API page lists legacy bare ids, naming gpt-image-2 and nano-banana-2 as examples, and says they are accepted as aliases for their org/slug equivalents. That is the only Nano Banana id the docs name.

The docs do not name a Nano Banana 3 or other variants, so a request for one would not be something to rely on. The reliable check is the catalog: GET /v1/images/models lists the ids and pricing the endpoint accepts. A model that is not in that response is not available to you.

curl "https://api.sume.com/v1/images/models" \
  -H "Authorization: Bearer $SUME_API_KEY"

A rule for future model names

When a new name appears in search, check three things before changing code: the vendor's own announcement, the model list of your API provider, and the exact id string the list uses. Pin the id from the list, not from a headline.

If you want Sume to choose, sume/auto is the Sume-only model value for images. Sume picks the family and never discloses which one ran, so use a pinned id when you need repeatable output.
