Fable 5 Pricing: $10/$50 per Million Tokens Explained

Specs & benchmarks informational Last reviewed Updated

How much does Fable 5 cost?

Fable 5's standard, post-introductory pricing is $10 per million input tokens and $50 per million output tokens. Because Fable 5 and Mythos 5 share an underlying model, these rates also describe Mythos 5's reference pricing.

The introductory window

From June 9 to June 22, 2026, Fable 5 was included free for Pro, Max, Team, and Enterprise subscribers. Starting June 23, 2026, those users moved to usage-based billing at the standard $10/$50 rate.

How Fable 5 compares

Model Input ($/M) Output ($/M)
Fable 5 / Mythos 5 $10 $50
Opus 4.8 $5 $25
Sonnet 4.6 $3 $15
Haiku 4.5 $1 $5

Fable 5 lists at roughly double Opus 4.8 and a tier above it in capability, which is consistent with Mythos-class sitting above Opus. If your workload does not need Mythos-class capability, Opus 4.8, Sonnet 4.6, or Haiku 4.5 may be substantially cheaper.

Availability and where it runs

Fable 5 reached general availability on the Claude API, the Claude Platform on AWS, Amazon Bedrock, Google Cloud, and Microsoft Foundry. Note, however, that a June 12, 2026 export-control directive suspended access, so confirm current availability before budgeting.
