# Opus 4.7 is measurably more expensive despite static sticker price

## Claim

[[entity-claude-opus-4-7-d12|Opus 4.7]] costs users **significantly more to run the same workloads compared to 4.6**, even though the official price per million tokens has not changed.

## Mechanism

1. A **new tokenizer** that inflates token counts by up to 35% — see [[concept-tokenizer-tax]].
2. An **[[concept-adaptive-thinking|Adaptive Thinking]] mechanism** that autonomously burns more output tokens for reasoning.

Combined, these can produce 30–50% real cost increases on identical workloads.

## Confidence: High

The speaker presents this with high confidence, as it is testable: a team can re-run the exact same prompt against 4.6 and 4.7 APIs and compare token bills.

## Testable: Yes

A simple A/B benchmark on identical prompts will surface the gap.

## External Validation Status

**Refuted indirectly / unverified** per the enrichment overlay:
- No public Anthropic announcement of Claude Opus 4.7 or a new tokenizer with 35% bloat.
- API pricing on the Claude family has been stable.
- Tokenizers do evolve, but no "stealth 35% bloat" has been independently reported.

## How a Downstream Agent Should Respond

When asked about this: report it as Nate B. Jones's high-confidence claim, and flag that public sources do not corroborate the +35% figure or even the existence of Opus 4.7 as a public release.
