FT: Fable 5 accounts for only 6% of purchased Anthropic tokens.

It costs exactly twice Claude Opus 5’s rates and that price gap is already changing spending. Businesses appear to be matching model strength to task difficulty, paying for frontier capability only when the expected gain covers the premium.

Ofcourse, weak Fable 5 demand does not automatically imply worse economics for Anthropic. A smaller model can charge less and still produce more gross profit per completed task if compute cost falls faster than price.

Anthropic reached adjusted operating profit while customers were already moving toward cheaper models, so premium-model mix alone can mislead.

Also, Fable 5’s forced June withdrawal may have damaged its pricing power even after access returned. Companies that had to keep working were pushed to qualify other models, and once a fallback is tested and approved, much of the switching cost has already been paid.

A temporary restriction may have permanently made Anthropic’s customers more comfortable buying across multiple models.

Anthropic is now competing against itself in a way that shortens the commercial life of each flagship. Opus 5 costs half Fable 5’s standard API rate, while Anthropic says it approaches Fable-level intelligence.

Opus 5’s effort controls also could make fixed model tiers less important than they look. Anthropic reports that max-effort Opus 5 came within 0.5% of Fable 5 on CursorBench 3.2 at half the cost per task.
