Claude Opus 4.8 is Anthropic’s Opus-tier flagship for state-of-the-art long-horizon
\nagentic work, coding and knowledge tasks. It runs adaptive thinking only, and carries a
\n1M-token context window at standard pricing \u2014 there is no long-context premium, which
\ndistinguishes it from several rivals that step the input rate up once a prompt passes a
\nthreshold. At $5 in \/ $25 out per million tokens it sits squarely in the frontier bracket.<\/p>\n
The no-premium 1M context is the practical reason to choose it. Models that double their
\ninput rate above 200K tokens make large-context work unpredictable to budget: the same
\nfeature costs a different amount depending on how much a user pasted in. Opus 4.8 bills the
\nsame rate from the first token to the millionth, so a retrieval-heavy application can size
\nits prompts around what produces the best answer rather than around a pricing cliff. It has
\nsince been joined by Claude Opus 5, which ranks higher on the Artificial Analysis
\nIntelligence Index at identical pricing \u2014 so for new builds, check whether Opus 5 is
\navailable in your region and provider before defaulting to 4.8.<\/p>","protected":false},"excerpt":{"rendered":"
