title: Claude Opus 4.8: Same Price, Cheaper Fast Mode

## Quick Answer

Claude Opus 4.8 launched at the same base price as Opus 4.7: $5 per million input tokens, $25 per million output tokens. Fast Mode dropped from $30/$150 to $10/$50 per million tokens, a real cut for latency-sensitive workloads. If Fast Mode looked too expensive against 4.7, re-run the math against 4.8's numbers.

## What's actually changing

Claude Opus 4.8 launched 2026-05-28 at the same base pricing as its predecessor: $5 per million input tokens and $25 per million output tokens, according to third-party pricing-tracking coverage (finout.io), not confirmed against Anthropic's own pricing page directly. On its own, that reads as no change at all.

Fast Mode tells a different story. The same source reports Fast Mode's price fell from $30 per million input tokens and $150 per million output tokens under Opus 4.7, to $10/$50 under Opus 4.8, a figure that matches [Anthropic's own Claude pricing page](https://docs.claude.com/en/docs/about-claude/pricing). That is a real reduction in a mode specifically built for latency-sensitive workloads that pay a premium to get responses faster.

## Structural Comparison Matrix

| Operational Aspect                          | Opus 4.7                   | Opus 4.8                          |
| :------------------------------------------ | :------------------------- | :-------------------------------- |
| **Base price (input/output per MTok)**      | $5 / $25                   | $5 / $25 (unchanged)              |
| **Fast Mode price (input/output per MTok)** | $30 / $150                 | $10 / $50                         |
| **Tokenizer**                               | Introduced in this version | Inherited unchanged from Opus 4.7 |

## Fix it: re-run the Fast Mode math

Anyone who evaluated Fast Mode against Opus 4.7's $30/$150 pricing and decided the latency benefit wasn't worth the cost has a real reason to revisit that decision under Opus 4.8. A workload that pays for Fast Mode specifically to cut response time now does so at roughly a third of the previous rate, which changes the break-even point against standard mode meaningfully, not marginally.

Base pricing staying flat is worth noting for a different reason: it means the price cut is isolated to Fast Mode specifically, not a general Opus 4.8 discount. Don't assume standard-mode costs moved just because Fast Mode did.

The [LLM Pricing Calculator](/tools/llm-pricing-calculator/) has both Opus 4.7 and 4.8, standard and Fast Mode, as selectable options — a faster way to re-run this exact break-even math against your own token counts than doing it by hand.

Both the base-price figure and the Fast Mode figures are paraphrased from finout.io's Claude Opus 4.8 pricing breakdown, tied to the model's 2026-05-28 launch, not confirmed against Anthropic's own pricing page directly.
