What happened

Pulse files it as a product change (feature added). Pulse's latest capture (Nov 9, 2026) lists grok-4.7 at $0.50 per 1M input tokens (cached) + $6 per 1M output tokens, grok-4.20-0309-reasoning at $2.50 per 1M output tokens + $0.40 per 1M input tokens (cached, long context), grok-imagine-video at $0.07 per output second (720p) + $0.01 per input second of video, grok-4.6 at $6 per 1M output tokens + $0.50 per 1M input tokens (cached) and grok-4.5 at $0.60 per 1M input tokens (cached, long context) + $2 per 1M input tokens.
