Claude ProPrimary Usage limits not disclosed | $20 | ~392 chats | 3,000 tokens | Anthropic says Opus 4.8 adds effort control, defaults to high effort, supports extra/xhigh or max effort for harder work, and has increased Claude Code rate limits for higher-effort usage. |

Released May 28, 2026, Claude Opus 4.8 is Anthropic's current flagship and its most capable publicly available model. It is best suited to complex agentic coding, legal and financial document analysis, deep multi-step reasoning, and long-running autonomous tasks. The meaningful upgrades over 4.7 are a dramatic improvement in mathematical reasoning, meaningfully better honesty (it flags its own mistakes rather than quietly moving on), and efficiency gains that mean it uses around 35% fewer output tokens to do the same work — so you actually get a little more for your money despite the unchanged rate card. The honest caveats: it is expensive at $25 per million output tokens, which adds up fast on any high-volume or long-session workflow. On claude.ai, users now have control over the amount of effort Claude puts into a task, but Pro plan rate limits are real and noticeable if you push it hard — heavy users will hit the ceiling. It is also slower than average at inference speed, so it thinks longer before responding. For chat, summarisation, and general Q&A, Sonnet 4.6 covers 90%+ of workloads at 40% lower per-token cost — most buyers do not need Opus for everyday tasks. AnthropicFinout Bottom line: Opus 4.8 is genuinely the best model for serious, sustained, complex work. It is overkill and quietly costly for anything routine — and if you hit the rate limits on a Pro plan, the frustration will feel disproportionate to what you are paying.
