Max upgrade or the $100 credit — which side of the split are you on?
From July 20, Fable 5 stays included on Max and Team Premium (up to 50% of weekly limits), while Pro runs it on usage credits — with a one-time $100 credit. Two questions, honest math, a verdict:
Assumes ≈0.6M input + 0.15M output tokens per focused hour at the published $10 / $50 per-million credit rate — about $13.50/hour. Interactive chat runs lighter; heavy agentic runs heavier. Plan-included use is capped at 50% of your weekly limit on Max, so extreme agentic load can exceed even Max caps. Estimates, not quotes.
New since July 24 · the third option
Opus 5 may make this whole question moot. It ships at $5/$25 — half Fable 5's rate — is included on Pro (no credits needed), and Anthropic claims nearly all of Fable 5's intelligence. If your work doesn't provably need the flagship, the cheapest correct answer since July 24 is often: stay on Pro and use Opus 5. The honest comparison →
