Opus 5 Surpasses Fable 5: Anthropic Shuffles Pricing Deck, Redrawing Startup Landscapes

News from early this morning: Anthropic dropped Claude Opus 5 on the table, priced at $5/$25 per million tokens. If you only looked at the name, you might think it's a mid-tier model—stronger than Sonnet but weaker than Fable. But once the data came out, Opus 5 surpassed Fable 5 on multiple benchmarks. What does this mean? A rare "inversion" has appeared within Anthropic's product line: the cheaper model is actually stronger.
