xai-grok-onboarding

🟢 xAI OAuth Onboarding Use any active xAI account — X Premium, X Premium+, SuperGrok, or SuperGrok Heavy — for grok-4.3 , grok-build-0.1 , grok-4.20-* and multi-agent models. No separate API key needed. This is standard OAuth 2.0 (RFC 8628 Device Authorization Grant), not a vendor-custom flow. Tier → model access The JWT issued by auth.x.ai carries a tier claim; higher tiers unlock more models from /v1/models . Observed mapping (xAI does not publish this officially): Tier Subscription Approx. model access 1 X Premium ($8/mo) grok-4.3 baseline 2 X Premium+ ($16/mo) + grok-4.20-0309 variants 3 SuperGrok ($30/mo) + reasoning models 4 SuperGrok Heavy ($300/mo) + grok-build-0.1 + multi-agent status() reports the user's tier so they know which models will be available.
