This is exactly the philosophy: don't bolt on efficiency, design for it from day one.

MFA + AFD aren't tricks. They're what lets Step 3.7 Flash serve at a fraction of the KV-cache cost.

Huge thanks to @FireworksAI_HQ for making Step 3.7 Flash one-click to run.

Go build something agentic with it.
