Claude Fable 5 - The Model That Does What the Last One Promised
I gave Claude Code a broken dashboard counter yesterday. It ran. It made changes. It told me it was fixed. It wasn't fixed.
This morning I handed the same problem to Claude Fable 5, Anthropic's new Mythos-class model, released June 9th. Under a minute... it was actually fixed.
It has real implications for how you route your work, especially with a billing cliff landing on June 23.
In this video:
→ What "The Confident Wrong" is and why it's costing you more than the bug itself
→ What Claude Fable 5 actually is (and how it differs from Opus 4.8)
→ The pricing reality: $10/$50 per million tokens, and when the 2x premium is actually worth it
→ The Meter Flip: why the free window matters and what happens when it closes
→ The 3-tier routing framework I'm using starting today

🤖 Need local AI agent and/or model security?
ORILink is lightweight middleware that installs at the model layer (local runtime only), before inference. Because "my agent went rogue" is not a postmortem anyone wants to write.
Local only, you're data stays on your machine.

(Disclosure: ORILink is my own product. I built it.)
