Claude Opus 4.8 ships at the same price with 4x fewer missed code flaws

Anthropic released Claude Opus 4.8 on May 28. The headliner for anyone running coding agents: Opus 4.8 is roughly 4x less likely than Opus 4.7 to let code flaws pass unremarked, per Anthropic. API pricing stays at $5/$25 per million input/output tokens, per Anthropic. GitHub shipped Opus 4.8 to Copilot the same day at a 15x premium request multiplier, per GitHub's changelog, landing three days before usage-based billing rolls out on June 1. If you are weighing Copilot Pro against Cursor Pro for agentic work, the cost crossover matters right now.
