DEPLOYif you run long agentic coding tasks
WHAT SHIPPEDClaude Opus 4.8 is available today at the same price as Opus 4.7: $5 per million input tokens and $25 per million output tokens. Fast mode runs at 2.5x speed and is now three times cheaper than previous models.
THE CATCHThe model is around four times less likely than Opus 4.7 to let flaws in code it wrote pass unremarked, and early testers report it pushes back when a plan is unsound.
IF YOU RUNcodebase-scale migrations across hundreds of thousands of lines of code from kickoff to merge
