Claude Opus pricing just collapsed. 67% in one year.

Opus 4 (2025)Opus 4.7 (2026)
Output$75 / MTok$25 / MTok
Input$15 / MTok$5 / MTok

At this rate, Opus 4.8 will be $15. Maybe $10.

So I got curious: if prices are falling this fast… how much does Anthropic actually make per token? Spent a weekend doing napkin math. It’s probably wrong in three places. Please fix it in the comments.


What does one token actually cost?

Rent an H100 GPU: ~$2/hr (committed use discount).

At 500 tokens/sec with batching:

1.8M tokens/hr ÷ $2 = $1.11 per million tokens

Anthropic charges $25.

That’s a 23x markup. 💀


But that’s too simple

Add the real costs:

WhatPer MTok
Raw GPU$1.11
Infra overhead (networking, cooling, idle)$0.44
Training amortization ($300M ÷ 500T tokens)$0.60
Total unit cost$2.15

Still. $2.15 to make, $25 to sell. 10x margin, right?

Wrong. Nobody pays list price.

  • Cache hits: 98% cheaper ($0.50)
  • Batch API: 50% off
  • Enterprise: negotiated down

My guess: average effective price is ~$15-20/MTok.

Margin: still healthy at ~88%. But thinning fast.


The dirty secret: the tokenizer tax

Opus 4.7 introduced a “new tokenizer.” It uses 35% more tokens for the exact same text.

So that “$25” price tag? For the same work you did on Opus 4, you’re actually paying:

$25 × 1.35 = $33.75 effective

The real price drop isn’t 67%. It’s more like 55%.

Is this intentional margin engineering, or a genuine technical trade-off? You tell me.


So how much does Anthropic actually make?

R&D alone is $500M-$1B/yr. A hundred million free users. Safety research. Sales team. The next training run.

Tokens are profitable. The company isn’t.


My prediction

Opus 4.8: $15/MTok output. New tokenizer: 50% more tokens.

The headline will say “prices dropped again.” Your bill will stay the same.


Tell me where I’m wrong

  • Is 500 tok/sec per H100 realistic for a frontier MoE model?
  • What do enterprise contracts actually pay?
  • Is the 35% tokenizer overhead a margin play or a real trade-off?

If you work in AI infra, cloud pricing, or know Anthropic’s real costs — correct me in the comments.


I think about this stuff because I’m experimenting with this problem directly through Monet.
