Notes
ADDED 2026-10-08, read directly from platform.claude.com/docs/en/about-claude/pricing. STANDARD: input $10 / output $50 / cache write 5m $12.50 / cache write 1h $20 / cache read $1 per MTok. Batch halves input and output to $5 / $25. US regional endpoint 1.1x. CACHE READ IS $1, NOT $0.25. Mythos 5 and Fable 5 both read cached input at $1; Mythos 5.1 and Fable 5.1 read at $0.25. Same $10 / $50 headline across all four. Do not copy the 5.1 cache figure onto this row. Context Window and Max Output Tokens left EMPTY — not stated for this model in the pricing table.
