xAI Docs release notes

Tools

New page: Image Generation Tool — Use the image_generation built-in tool so Grok can generate and edit images (Grok Imagine) inside a Responses API conversation, including basic usage, the action parameter, editing input images, multi-turn editing, combining with other tools, streaming, and SDK support.
Tools overview now lists Image Generation among built-in tools and links to the new page.
Image generation related links point to the new tool page.
Pricing documents the Image Generation tool (image_generation) and points to Imagine API rates.

Voice API reference lists additional built-in voices (e.g. Carina, Zagan, Helix, Orion, Luna, Iris, and others).
Text-to-speech and speech-to-speech docs describe voice as any built-in voice ID or a custom voice ID (no longer a short fixed list in the parameter tables/examples).
