.

system
,
user
, or
assistant
 roles in any sequence for your conversation context.

logprobs

 and newer. These fields will be silently ignored if set.

Image input models

Maximum image size:
20MiB

Maximum number of images: No limit

Supported image file types:
jpg/jpeg
 or

.

Any image/text input order is accepted (e.g. text prompt can precede image prompt)

The knowledge cut-off date of Grok 4.6 is February 1, 2026.
Model Aliases
Some models have aliases to help users automatically migrate to the next version of the same model. In general:

<modelname>
 is aliased to the latest stable version.

<modelname>-latest
 is aliased to the latest version. This is suitable for users who want to access the latest features.

<modelname>-<date>
 refers directly to a specific model release. This will not be updated and is for workflows that demand consistency.

For most users, the aliased
<modelname>
 or
<modelname>-latest
 are recommended, as you would receive the latest features automatically.
