Claude Fable + Findustry AI

When the pace of model progress is this fast, you need a partner that helps you stay ahead. Today, Anthropic released Claude Fable 5, a Mythos‑class model, and it’s already live in Findustry AI.

Our Benchmark shows it’s the most capable, but also most expensive, LLM for payments workflows yet.

The base Fable 5 scores 80%, compared to a score of 70% for Opus 4.8, but is also 117% more expensive. Reach out to learn more about how our product matches the right model to every task based on capability and cost.

Findustry AI founder Jonathan Razi commented, “Just like the surcharging map was a signature of the CardX brand, and our state law expertise made us the most trusted partner in that space, the Benchmark is becoming signature thought leadership for Findustry AI.

Here’s the critical gap it fills: if you’re building a payments application that uses LLM responses in its workflows, how do you know which model is best for payments use cases among the many options, such as GPT, Gemini, Grok, Opus, or—as of today—Fable?

Our Findustry AI Benchmark is the first AI benchmark measuring LLM capabilities for payments workflows, not general tasks like math or coding. It enables us to choose the right LLM for every task and—perhaps most importantly—gives us the foundation to make proprietary improvements on top of base models.

We’re excited about the value this is providing our customers and partners!”
