Versus frontier models on the same benchmark.

Every model below enforced the same FINRA rulebook on the same lawyer-annotated messages. A general model has to read 40,000 to 68,000 tokens of rules on every call. Anchor already knows them, so it reads the message. Swap any column from its dropdown.

Measured on ZeroDrift's third-party FINRA benchmark: a test set of emails written by a lawyer and annotated by three more, with a violation counted where two of the three agreed. Every model was given the full FINRA rulebook. Frontier costs are what each model consumed per message at its provider's September 2026 list price. Violations missed is 1 minus recall. Recall and latency were measured on Anchor 3.0 and are shown for every Anchor model. Your own rules add one charge per 10 rules on ZeroDrift and are not included above.

Questions developers ask before they sign up.

What counts as a message?One message of up to 2,000 tokens, checked against your rulepacks and policies, rewritten if needed, and verified. That is one charge at your model's price.
Can I switch models?Yes. Set the model on each request, switch any time, or run different models for different tasks. Each message bills at the price of the model that handled it.
Do rewrites cost extra?No. On Anchor 3.0 and Anchor 3.0-max the rewrite and its verification are part of the same charge. Anchor 3.0-mini is detection only.
Are my rules trained in, or read at run time?Anchor 3.0 LoRA-trains your rules into the model weights: the first 5 are free, then $10 per rule trained or retrained. Anchor 3.0-max reads your uploaded policy or rules at run time, with no LoRA training. On both, every 10 rules add one message charge.
What happens after the $10 in free credits?Usage is billed to the card on file at the same per-message prices. There are no seats, minimums, or platform fees.
When should I talk to sales?For in-VPC deployment or volume pricing. Everything else starts with a signup.
