What has been updated?
The developer documentation now introduces Grok 4.7 as the primary text and coding model. Image generation, video, and voice interaction are separate services; not all features should be considered traits of a single model.
Instant news without search?
According to the API documentation, the Web Search or X Search tool must be enabled for recent events. Simply asking "What is today's news?" from a model without these tools does not create a reliable news source.
