claude-opus-4-8 is live · Anthropic’s flagship —— Agentic coding rises from 64.3% to 69.2%, it’s about 4x less likely to overlook code flaws, more honest with a lower deception rate, and adds dynamic workflows plus effort control. Priced identically to Opus 4.7 ($5 / $25 per 1M tokens) — an upgrade at no extra cost; existing Opus workflows just swap the model name.
