Frequently asked questions

What do the Corsac evals for fal test?+

Each eval pack tests fal's public product surface — including Billing Concurrency Media Lifecycle, Content Safety Refusal Rights, and Image Video Audio Generation — against graded scenarios covering adversarial robustness, workflow quality, safety gates, and operator quality. Every pack is runnable in Corsac with your own data.

How are the fal evals scored?+

Pass/fail checks plus an LLM judge scoring 1–5 against each of the 66 fal cases — from Content Safety Refusal Rights (10 scenarios) down to the smallest pack — its own expected behavior, with critical-severity flags and negative controls. Only judge-passed evals are published to the fal library.

How many test cases does the fal library include?+

The fal eval library includes 66 graded test cases across 8 eval packs, the largest being Content Safety Refusal Rights with 10 scenarios. Each case defines an input, expected behavior, and pass/fail criteria.

How do I run these evals against fal or my own agent?+

Request the library with your work email above and we'll set it up in a Corsac workspace, where you can run all 8 fal packs — Billing Concurrency Media Lifecycle and Content Safety Refusal Rights and the rest — against fal or your own agent with your own data.
