xAI
Grok language, image, video, voice and transcription models, with release-specific capabilities and billing.
14 current language/media entries, two named voice models and nine retired originals reviewed. Older and partner-hosted releases, plus complete media rate schedules, remain under review.
Start with the job your model needs to do. Then narrow by capabilities, provider and price.
Compare every model with the same request.
Estimate = (input tokens × input price + output tokens × output price) / 1,000,000. Include conversation history in input and billed reasoning in output. Input-only decision models ignore the output setting; enter all billed input for one decision, including its question and criteria. Media, tools and discounts are separate.
