xAI has not published a model card, API ID or pricing for Grok 4.8; developer docs still list grok-4.6

Grok 4.8 exists as a named training run in Musk's posts, not as a product developers can call; xAI's docs and marketplace listings remain unchanged at grok-4.6.

In this brief: 2 sections 1 min read

- xAI's model list and API documentation continue to name grok-4.6 as the latest public model.
- There is no model page, pricing, context-window spec, or benchmark card for any grok-4.7/4.8 entry.
- Third-party trackers (per the article) list nothing newer than grok-4.6 for live API use.
- Until xAI publishes an official model card and API identifier, developers must assume the live flagship remains grok-4.6.
- Any integration, cost modelling, or production migration should wait for an official release and verifiable specs.
- Claims about parameter counts or speedups are founder statements until confirmed in documentation or benchmarks.
