Publisher excerpt: Anthropic's Opus 4.7 matches its predecessor's per-token price, but each request ends up costing significantly more. The reason: a new tokenizer that breaks the same text into up to 47 percent more tokens. Early measurements show what that shift means in practice for Claude Code users.
