The OnAirToday AI Progress Tracker recorded a verified change to xAI's Grok 3 Mini Beta (version grok-3-mini-beta): Grok 4 shipped in July 2025; this profile remains specific to Grok 3 Mini Beta.

Grok 3 Mini Beta is xAI’s text-only reasoning model for mathematical, scientific and coding tasks, with configurable reasoning effort. Its documented API pricing is $0.30 per million input tokens and $0.50 per million output tokens; newer Grok generations have since shipped.

What changed in this review:

• Grok 3 Mini also has the stable API identifier grok-3-mini; the beta identifier is retained here.

Teams building on Grok 3 Mini Beta should confirm limits, pricing and benchmark coverage against the vendor's own documentation before relying on these figures.
