Claude Code fast mode broken for 20x Max subscriber, user reports billing mismatch

RileyRalmuto · x · 2026-10-15

X user RileyRalmuto reports that fast mode has never worked for him in Claude Code: it appears usable only via API credits rather than his 20x Max subscription, and his unused bonus API credits aren't picked up either. He publicly tagged Anthropic asking for help. The report suggests a possible billing-channel mismatch between subscriptions and API credits for the fast mode feature.
