deprecated

This endpoint has been deprecated and may be replaced or removed in future versions of the API.

Will answer a question about text given in a prompt. This interface is deprecated and will be removed in a later version. New methodologies for processing Q&A tasks will be provided before this is removed.

Query Parameters

nice boolean

Setting this to True, will signal to the API that you intend to be nice to other users by de-prioritizing your request below concurrent ones.

application/json

Bodyrequired

hostingHosting (string)nullable
Optional parameter that specifies which datacenters may process the request. You can either set the parameter to "aleph-alpha" or omit it (defaulting to null).
Not setting this value, or setting it to null, gives us maximal flexibility in processing your request in our own datacenters and on servers hosted with other providers. Choose this option for maximum availability.
Setting it to "aleph-alpha" allows us to only process the request in our own datacenters. Choose this option for maximal data privacy.
Possible values: [aleph-alpha, null]
querystringrequired
The question to be answered about the prompt by the model. The prompt may not contain a valid answer.
documents object[]required
A list of documents. Valid document formats for tasks like Q&A and Summarization.
These can be one of the following formats:
• Docx: A base64 encoded Docx file
• Text: A string of text
• Prompt: A multimodal prompt, as is used in our other tasks like Completion
Docx and Text documents are usually preferred and have optimisations (such as chunking) applied to make them work better with the task being performed.
Prompt documents are assumed to be used for advanced use cases, and will be left as-is.

An array of prompt items for multimodal request. Can support any combination of text, images, and token ids.

Text
typestringrequired
Possible values: [text]
datastringrequired
controls object[]
Array [
startintegerrequired
Starting character index to apply the factor to.
lengthintegerrequired
The amount of characters to apply the factor to.
factornumberrequired
Factor to apply to the given token in the attention matrix.
• 0 <= factor < 1 => Suppress the given token
• factor == 1 => identity operation, no change to attention
• factor > 1 => Amplify the given token
token_overlapstring
What to do if a control partially overlaps with a text token.
If set to "partial", the factor will be adjusted proportionally with the amount of the token it overlaps. So a factor of 2.0 of a control that only covers 2 of 4 token characters, would be adjusted to 1.5. (It always moves closer to 1, since 1 is an identity operation for control factors.)
If set to "complete", the full factor will be applied as long as the control overlaps with the token at all.
Possible values: [partial, complete]
Default value: partial
]
Image
typestringrequired
Possible values: [image]
datastringrequired
An image send as part of a prompt to a model. The image is represented as base64.
Note: The models operate on square images. All non-square images are center-cropped before going to the model, so portions of the image may not be visible.
You can supply specific cropping parameters if you like, to choose a different area of the image than a center-crop. Or, you can always transform the image yourself to a square before sending it.
xinteger
x-coordinate of top left corner of cropping box in pixels
yinteger
y-coordinate of top left corner of cropping box in pixels
sizeinteger
Size of the cropping square in pixels
controls object[]
Array [
rect objectrequired
Bounding box in logical coordinates. From 0 to 1. With (0,0) being the upper left corner, and relative to the entire image.
Keep in mind, non-square images are center-cropped by default before going to the model. (You can specify a custom cropping if you want.). Since control coordinates are relative to the entire image, all or a portion of your control may be outside the "model visible area".
leftnumberrequired
x-coordinate of top left corner of the control bounding box. Must be a value between 0 and 1, where 0 is the left corner and 1 is the right corner.
topnumberrequired
y-coordinate of top left corner of the control bounding box Must be a value between 0 and 1, where 0 is the top pixel row and 1 is the bottom row.
widthnumberrequired
width of the control bounding box Must be a value between 0 and 1, where 1 means the full width of the image.
heightnumberrequired
height of the control bounding box Must be a value between 0 and 1, where 1 means the full height of the image.
factornumberrequired
Factor to apply to the given token in the attention matrix.
• 0 <= factor < 1 => Suppress the given token
• factor == 1 => identity operation, no change to attention
• factor > 1 => Amplify the given token
token_overlapstring
What to do if a control partially overlaps with an image token.
If set to "partial", the factor will be adjusted proportionally with the amount of the token it overlaps. So a factor of 2.0 of a control that only covers half of the image "tile", would be adjusted to 1.5. (It always moves closer to 1, since 1 is an identity operation for control factors.)
If set to "complete", the full factor will be applied as long as the control overlaps with the token at all.
Possible values: [partial, complete]
Default value: partial
]
Token Ids
typestringrequired
Possible values: [token_ids]
datainteger[]required
controls object[]
Array [
indexintegerrequired
Index of the token, relative to the list of tokens IDs in the current prompt item.
factornumberrequired
Factor to apply to the given token in the attention matrix.
• 0 <= factor < 1 => Suppress the given token
• factor == 1 => identity operation, no change to attention
• factor > 1 => Amplify the given token

max_answersinteger
The maximum number of answers to return for this query. A smaller number of max answers can possibly return answers sooner, since less answers have to be generated.
Possible values: >= 1 and <= 200
Default value: 30
