hi team, i noticed this problem when i tried to access ByteDance Seedream 4.0 model (from together ai)
it should be available looking at together ai, and the costmap
the error
tracing parts of the code, it looks like the js lib failed to determine if this should use the together ai service, because there isn't the bytedance prefix (adding it should fix it?)
image prefix
|
const TOGETHER_IMAGE_MODEL_PREFIXES = [ |
|
'black-forest-labs/', |
|
'stabilityai/', |
|
'togethercomputer/', |
|
'playgroundai/', |
|
'runwayml/', |
|
'lightricks/', |
|
'sg161222/', |
|
'wavymulder/', |
|
'prompthero/', |
|
]; |
video prefix
|
const TOGETHER_VIDEO_MODEL_PREFIXES = [ |
|
'minimax/', |
|
'google/', |
|
'bytedance/', |
|
'pixverse/', |
|
'kwaivgi/', |
|
'vidu/', |
|
'wan-ai/', |
|
]; |
this is where it determines which AI service it chooses, by default because it doesn't found any, it just uses the one it initialized with, which is the openai, which explains why error message shows gpt image, dalle, etc

let AIService = "openai-image-generation" |
|
if (options.model === "nano-banana") |
|
options.model = "gemini-2.5-flash-image-preview"; |

const driverHint = typeof options.driver === 'string' ? options.driver : undefined; |

if (driverHint) { |
