Fable left the subscription. Don’t chase it at $10/$50.

As of July 7, Fable 5 is API-only at $10 in / $50 out per Mtok. Most of what you ship doesn’t need it — and there’s a receipt to prove which parts do.

Before you go hunting for a deal

There is no cheaper Fable.

There is no cheaper Fable. Anyone selling you one is selling you something else — resold quota, a mystery key, a different model wearing the name. The price is the price.

The honest move isn’t chasing a discount that can’t exist. It’s deciding which of your work still needs Fable — and moving the rest, with proof. Keep your provider. Keep your keys. Get a verdict per workload.

Run №000 · 07.02.26

Nine models. One job. Five passed.

One open run: build a working page, graded by an 8-point Playwright audit, one shot each. Every model that passed cleared the same bar — same quality, wildly different bills.

39 times the price spread for the same passing grade. Same results for less isn’t a pitch here — it’s a measurement.

Credit where due: GPT 5.5 shipped the best-designed page of the run. Sometimes the frontier earns its price. The point is knowing which of your workloads it earns it on.

Honesty note: Fable 5 DNF’d Run №000 on a transport error — a failure in the pipes, not the model (so did Opus 4.8, Kimi K2.5 and MiniMax M2.7). It re-enters the blind ledger under the same audit. №000 was an open run; the public ledger holds blind contests №001–005 ↗.

The mechanism

Proof, not promises.

Step 1
Bring your keys.

Point your OpenAI and Anthropic keys at our pass-through proxy. Same models, same outputs, read-only. You keep your provider.

Step 2
Pareto — our model — runs in shadow.

It re-runs a sample of your real requests async, off the production path. Users never see it.

Step 3
You get the verdicts.

Quality and price per workload, re-gradable from the transcripts. Nothing moves without your sign-off.

MOVE same-or-better at lower cost — verified savings, flip when ready
SHADOW still comparing — free
KEEP the frontier won — pays us $0

Pareto wasn’t ready to enter Run №000 — once it ships, it enters every contest under the same audit.

Our pricing is our proof. We charge nothing until you flip.

A KEEP verdict pays us zero — so you can see exactly where the savings come from, and trust the MOVEs.
